Building a robotic arm?

In Science next term, we've been told that we'll need to build a robotic gripper. All it has to do is pick up a cup. I've been having a look around, and the balloon idea isn't practical because if the cup was full it wouldn't work. And I'm okay with spending a little money, but I'd rather not spend $100 or anything on a kit. So what's a good idea for me?

Arduino robotic arm

Hi, I just made a 5 DOF robotic arm and its not working for some reason I'm not sure whether if its the code problem or the mechanical part of the robothere's the Arduino code:#include #include Servo servo1; Servo servo2; Servo servo3; Servo servo4; Servo servo5; Servo servo6; int bluetoothTX = 11; int bluetoothRX = 12; SoftwareSerial bluetooth(bluetoothTX, bluetoothRX);void setup() { // put your setup code here, to run once: servo1.attach(3); servo2.attach(4); servo3.attach(5); servo4.attach(6); servo5.attach(7); servo6.attach(8); Serial.begin(9600); bluetooth.begin(9600); } void loop() { // put your main code here, to run repeatedly: if(bluetooth.available()>0) { int servopos1 =; int servopos2 =; int servopos3 =; int servopos4 =; int servopos5 =; int servopos6 =; Serial.println(servopos1); Serial.println(servopos2); Serial.println(servopos3); Serial.println(servopos4); Serial.println(servopos5); Serial.println(servopos6); servo1.write(servopos1); servo2.write(servopos2); servo3.write(servopos3); servo4.write(servopos4); servo5.write(servopos5); servo6.write(servopos6); } }

Help wiring and programming a Robot Arm? Answered

I have been building a robot arm for a competition, and I have the structure completed. I am very new to Arduino, and have little know-how when it comes to wiring properly and even less when it comes to programming.

Does anyone know how to program a repetative motion robot (see description)?

This is mostly out of a theory and curiosity, but if I were to make a robotic arm and I wanted to make it do repetativve motions, how would I make It recognize/remember the movments and how would I make it perform them. It would be a direct teaching unit (meaning I would move the robot and it would remember the movments) so how would I make it run or hook it up to a computer and how would I program it with the direct teaching. If this impossible or extremeny difficult, please recommend a different technique. Please give me good, detailed instructions.

Brains for a robot?

It's time I turn yet again to the forums for advice, this time on recommended robot brains! [Serious] I have a project for a class requiring design, construction and programming of something. More than half of my fellow students are doing clocks of some sort, be they binary or nixie tube. A friend of mine is doing a holonomic robot, and my plan was to do a walking robot, based on ideas like the WowWee robosaurus, using a simple tail and head to balance and few motors to run it in comparison to any conventional biped. As far as servos, I was hoping to use something like the HerculeX or other serially connected servo, so I can just daisy chain the few I would need and simplify the wiring, as well as get experience with serially addressing things. Planned sensors are 2-4 IR rangefinders, 2-4 wire whiskers and one tilt switch to turn it off if it tips over. Sensors I'd love to add would be something like a super basic camera for simple machine vision if I ever learn to code that well, but I doubt that will be the case; and the LIDAR thing from the Neato XV-11 which is again unlikely. Things I was looking at for super basic use included: Arduino, HC11 MC (backplane type), BASIC Stamp, PIC. For a little more complexity I was seriously considering things like the Freescale Tower ARM, Gumstix or other. I'd love to have the serial servos, sensor assemblies and the camera and have integration with Robot operating system through an onboard computer, but I have no idea what to use to setup ROS or what would be best, or if my plan of parts to use is even good enough. In other words, what ideas should I throw out as impossible or what would I need for say, ROS use? Ideally i want to do a semi autonomous robot, so that i don't have to manually direct it everywhere, but I'd still be keeping an eye on it when it's running so it doesn't break something. If I understand ROS correctly I can use an external computer to control it, but I can also let it be autonomous? Coding math and logic in the machine language for a Z80 computer doesn't really prepare for robot building, although the class is basically a teach programming basics and throw you into the deep end. [/serious] Thank you in advance for your help!

Robotic Gripper Runs on Coffee and Balloons - Updated with video

I'm just on FIAH with these Topics. But this one's cool too. Via ScienceDaily: A collaboration between researchers from Cornell, University of Chicago, and iRobot has resulted in a robot gripper that conforms to practically any object. From the article: Here's how it works: An everyday party balloon filled with ground coffee -- any variety will do -- is attached to a robotic arm. The coffee-filled balloon presses down and deforms around the desired object, and then a vacuum sucks the air out of the balloon, solidifying its grip. When the vacuum is released, the balloon becomes soft again, and the gripper lets go. This sounds like another hi-tech device that could easily be duplicated by a DIYer. All you need is a balloon, coffee grounds, and a vacuum pump. Update 2 November: Found the video! It gives a much better idea of how the thing works. Via, image from same.

unfinished,5 DOF Robotic Mechanical ARM

5 DOF Robotic Mechanical ARM Required Material of project:- 1. Basic Servo Tower pro 9g*4 2. Header pins Male female*2 3. Arduino Nano*1 4.10kΩ Resistor resistance*2 5. Trimmer Potentiometer track Linear; maximum resistance 10kΩ*4 6. Tactile push button*2 7. Blank circuit board*1 8. Acrylic strips for Robot & potentiometer body*2 9. Wires, Button, Switch 10.Balsa wood, Metal, Plastic Procedure:- Arrange all necessary items.. Please go through the attached images  for better understanding.. I divide whole project in two parts 1) Servo Motor assembly 2) Potentiometer assembly 1) Servo motor assembly: – Servo motor as J1, J2, J3, J4 fix the servo motors as shown in image use 3M tape to glue servo, use thin flexible plastic strip to make griper, make hole in center of each finger tie thread in that hole pass this thread from center hole and tie knot at the other end of thread with 4th servo motor’s knob, as you stretch thread finger get close vise versa. Fix whole arrangement on strong rigid base. 2) Potentiometer assembly: – Fix potentiometer as shown in figure name potentiometer as do previous R3, R4, R5, R6 this time place R6 separately for easy access this potentiometer control gripper to pick and place. Potentiometer arrangement symmetry must be same as servo arm. Fix whole arrangement on strong rigid base. Moving a little bolt from one side to the other side:- 1. Actuators / output devices: 4 micro servos 2. Control method: controlled by a PIC16F690       assembler firmware 3. CPU: PIC16f690 micro controller 4. Operating system: self made assembler code 5. Power source: 4.8V to 6V from 4 battery cells 6. Programming language: PIC Assembler 7. Sensors / input devices: teach in system with                         4 potentiometers       Making Processer:- The Potis are standard types and are screwed to the white plastic parts with their nuts. The axles are pressed into the transparent plastic part. The handle to move the teach-in-arm is a M3-Spacer and the socket is a plastic part with is normally used to fix balloons on a stick to hold it.                     move the motor itself by hand a little force is needed due to its permanent magnets, which create a small holding force. But inside the servo a lot of gears increase the force which you have to apply. If you move the servo by hand, you have to apply a much higher force. If you overcome the motors holding force, it starts to rotate an acts as a flywheel. So moving a servo by hand needs a high torque and its not easy to turn it to the position where you want it. ( Fan control modules for engine cooling of real cars have some extra parts to clamp the voltage which is generated, when you drive at higher speeds. In that case the fan works like a windmill and creates higher voltages than normal inside the power stage of the module.) And there were also a lot of other "problems" which had to be solved using my PIC Controllers. i.e. self made electronics for a RC-Excavator which works similar to the digital system used in slot cars. To replace a lot of wires between the rotating part of the excavator and the track unit, a small PIC 12F629 reads the pulses from up to 5 channels of a RC-Receiver and leads their information via a 2 wire connection to a second PIC12F629. At the second board the power is separated from the data. The PIC is reading the data, and generates the PWM output for the 5 Servo output connector. the 2 wire connection is made with a cheap 6,3mm mono microphone plug which is also used as the axle for the rotating part. The arm of the excavator is also powered by standard servos and so it was necessary to change the control behavior from proportional to integral so that the servos move like real hydraulic cylinders which are controlled by valves. I used the same 12F629 type for that job and added some features like adjustable limit positions and starting point programmable by one jumper, and automatic return to park position when missing the pulses for some seconds. The Software is simple:- Its working like a servotester for four axis. That means, every poti is connected to an analog in of the controller and all servos are connected to GPIOs. The controller reads each poti, does some scaling, so that the angle of the poti equals to the angle of the axis and finally he creates the PWM output 1-2ms pulse every 20ms for all servos. Teach mode:- After a reset the robot arm follows the teach in arm while simple mapping the analog inputs every 25ms to the servo motors. Pressing the button stores each servo position in a array. Play mode: The sketch reads the array step by step and moves the robot arm. For cool looking movements I added a routine calculates different micro steps for each servo to have moving start and end sync on all axis. Also added a ramp for soft increase/decrease velocity. Shorter travel distances the robot does slow, longer distances with faster speed.           The program moves the servos at full speed to the next position and a short delay time after each command allows all of the servos to reach their final position. That means that it is possible to increase the speed a little bit more by doing some fine tuning of the delay times after each command. The final thing which is still not implemented is the routine which saves the "Teach In" data 5 or 10 times per second, so that the controller is able to replay it in a loop with the original speed or with a lower or higher speed. Electrical Connection:- Provide separate power supply (5V DC 1amps) to the Servo motors . Don’t forget to short ground of both power source ( arduino + servo) 5 DOF Robotic Mechanical ARM :- 1. Use of Fiber on upper side 2. wooden spoon is a part of side body 3. cable tie *12 pieces use the robotic. 4. Some pices of wires 5. use scraw*4 6. Glue 7. some small clips Because to attached body 8. small size of plastic box 9. One pieces of  square fiber stand and one pieces small & medium  circular fiber  10.  L293D Motor Driver IC+IC Base KG143 11. Generic Elementz High Quality Nickel Plated 24*18 Points Bread Board*(2 pieces) and one plastic 12. Push Button Switch. Play Mode version 1.1 The gripper input is used to set the delay (0,1,3,15,60,300 seconds) after a loop is done. The switch (it was left from the project start) pauses the robot.        Thanks you:

Seeking engineering advice on mounting heavy weight in concrete ceiling

Hi all, I am designing/building a prop ceiling-mounted surgical arm (see reference photos attached) into a 15" concrete slab ceiling for a hospital room set for a tv show. I'm also attaching two sketches of the two different arms I plan on making and I'm hoping some of you clever engineering-types may be able to identify flaws in my schematics before I go too far with the design. If you see something that could pose a danger to the actors or have and alternative suggestion I would be grateful!!! Here are my concerns: 1) what are acceptable stresses on all joints due to weight distribution and actors moving the parts around? 2) the heavy duty industrial casters that tapcon into the ceiling: would they get pried apart as weight is applied gravitationally? 3) can the concrete ceiling handle the live stresses of actors moving the arms? 4) can the horizontal PVC arms handle the weight or do they require a welded metal skeleton? --------------------------------------------------------------------------------------------------------------------- Any feedback would be greatly appreciated; I'm in my research phase of this build now so please let me know your thoughts!!!

Robot Challenge Question

So, I recently got around to making an Instructable for my RC robot arm I built for my school's Science Olympiad team, with the intent of also entering the Robot Challenge. Lo and behold, I believed my Instructable eligible for not only the Robot Challenge, but also the Remote Control Challenge, so I clicked away and entered into both. I heard back that my entry was accepted for the Remote Control Challenge within less than one business day, but to my dismay, I have heard nothing back about the Robot Challenge. This is why I am calling upon the wise wisdom of this website, hoping to discover what my Instructable may lack to be entered into the Robot Challenge, so I can go about to add to it and be accepted into the elusive halls of the famed Robot Challenge on this glorious website. So, I guess, to be a bit more concise, is there something missing from my Instructable that is preventing it from being entered into the Robot Challenge (so I can modify it before the contest closes)? Thanks a million and one.

Control steppers with arduino or raspberry pi?

We have this robotic arm at our school that is broken and we are trying to make it work. The motors are shot and we have no idea were the controller went. We are just going to put stepper motors instead. The problem is we have no idea how to control the motors. So my question is: How can you control 6 stepper motors individually using an arduino uno, arduino mega, or raspberry pi?

Two way intercom design for tele-operated robot

Hi,I'm working on building a tele-operated robot that will be able to send signals generated by moving your arms and mapping these to the robot arms. I'm looking to add an intercom system to the robot that would allow for the operator to speak into a microphone and come out a speaker on the robot and a microphone on the robot so send audio that someone speaking to the robot generates to the operator.I've currently been looking into VOX circuits and walkie talkies but all walkie talkies I have seen require both sides to use a headset. It would be fine for the operator of the robot to use a headset but it would be better for the speaker and microphone on the robot to be out loud. Does anyone have ideas about how this type of system could be implemented? Could I replace the PTT button on a walkie talkie with a voice activated switch kit available online?Thank you.

Implementation of two way communication

Hi, I'm working on a project where we're working on a tele-operated robot and we are looking to include the ability to have a conversation. We would be looking to use earbuds and a microphone on the operator side and a speaker and microphone on the robot side. Does anyone know how to go about implementing this? It needs to be hands free on both ends as the operators arms are being mapped to the robots arms. Thank you.

making concepts out of cardboard

I dont have much money but i have some card board, i've made an actual length sword from an anime (just the outline and taped the extra cardboard pieces with tape) and a cartoon character robot arm out of cardboard (this one i made an actual glove-like arm with finger holes that i can actually wear) because i figured this would be a good way to have an idea of how i could make them when i finally get money to buy real materials to make them with real details... What do you all think bout this? is making concepts out of cardboard a good idea or what other cheap materials can i use to make better concepts?

Plushie Instructable Robot - Preview 1.0!!

Here's how far I've gotten with the Robot that I'm making. Patterns are hard, ya'll! You'll see the arm graveyard in the pictures. (Including the one that turned out like a condom - no idea about that one. Very weird.) I went through a lot of different bodies, too, but those aren't nearly as annoying. The last stumbling block is the head - after that it will be smooth sailing! I'm working on that right now. Keep in mind that I'm making these pieces out of felt - it's cheaper for practicing. The actual plushie will be made out of fleece. Yay! And the body will be less angular, too. The shoulders should be more rounded. The ends of the legs and arms will be sewn into the body seams. :D And now... the gallery. Complete with evil kitties that are trying to stall the construction.

Best motor and switch for this swinging arm?

I am trying to make the following: i need a 4 foot arm to swing parallel to the ground at a fulcrum. Only needs to travel 90 degrees one direction, then back 90 degrees to its original spot - Kind of like 1 windshield wiper running parallel to the ground the weight of the arm plus load at the end is roughly 10pounds this would be triggered by a single button thats the gist of it. Now if. I could tweak it... i would like one press of button A to move the arm 90 degrees then it stops. A second press of button A would move the arm back to where it originally was.  Or, if this is too costly, I could hold the button down while the arm cycles 90 degrees and back, releasing the switch when the arm reaches its desired location I need cheap options or at least a good place to start. I have zero coding or electronics knowledge thank you
