swarm bots...

I was watching the discovery channel a while ago and on a show abbout robots, the spoke of small robots called swarm bots. the seem to sense distance from each other and are able to trail each other single file, or (i'm sure) other formations. i would like to know if anyone could help me replicate this effect, but on a slightly larger scale.

Caught By The Bots Again

This is my third time being caught by that darn filter with a question for no reason!  Please do something about this because every time I have to report a bug to set it free.  My most recent question is in relation to making cement.  This is honestly getting to be quite a hassle especially considering you won't tell me why the bot caught it.  Has the integrity of this site really gone so bad that a computer has to harshly scrutinize everything that is posted?

Regarding bristle-bots.?

All the bristle-bots I have seen thus far have used offset, rotating masses to generate the vibration. I have just acquired a motor with a vibrating linear output. What direction should I point the motion for the most efficient bristle-bot? Front-to-back, or up-and-down?

Battle Bots Contest!

So, if you've seen the movie Real Steel you know what i'm talking about. Real Steel is boxing, fighting and wrestling humanoid robots. I posted this contest because I wanted to see how many people can make a humanoid that works, or modify a humanoid hat you can buy. Zibits, mini robots (about 3 in. tall), are pretty cool, saying that they only go forward, or 360 degrees. You can hack em, fight em and play with them. Also, WOWWEE makes really cool humanoids to hack into, for example Full sized Robosapien and Femisapien. Tri-BOIT and Robo-ROVER. Post an Instructable with a video if you want to, and please make a step by step guide on how to make your battle bot. If you make it from scratch you have a higher chance of winning, if you hack a ZIbit or make a mini robot you might win the mini battle bot contest. Wowwee toys are big so those are the big robot humanoid contest. Be creative and express your ideas, and remember you always have a great chance of winning. The naming of the robot types were just an example of cheap stuff you can find in most stores, use whatever you'd like to make the ultimate humanoid robot contest. If there are a  lot of people there will be one , to three, maybe five winners, if there are less than 10, there will be multiple winner depending on size, type and what they do, but there will always be one grand prize winner. Enjoy! Contest ends when I want it to.

What is up with all the 'bots?

I have gotten many comments on one of my Instructables from what appears to be 'bots. It's getting annoying and makes me wonder what they're getting out of it besides phishing for me to go to their websites (digitalsyndrome.com, for example). They have names like shoppingwombat, sneerstab, massespolenta, washtoes, mildfrequent, monkeyglom, etc.; either no pictures or photos of actresses as avatars. They describe themselves as "Unapologetic twitter advocate. Food maven. Problem solver. General analyst. Wannabe web specialist." and other inane terms.  Although they seem to abide by the rules of the site by being polite and use two-word comments like "that's calme" (sic), "Its trendy", "Its ideal", and so on, they are really getting to be a pain. Has anyone at Instructables looked into this obvious spamming?  Thanks!

Bee-Bot/Cluster-Bot/Zombie-Bot

I remember seeing a bot (a group of bots) on TechTV many years ago (had to have been... hell how many of you still even remember that great channel) where all the master would have to do is give the first bot directions, and it would just go near the other one (IR or RF) and it would pass on the message. All he did was give one bot the midi file for the star wars theme... and the bots organized themselfs to play the song with different notes divided out. He could basically tell them any command and they would work as a team to figure it out. I don't remember what it was called... they WERE cluster bots... but I thought he called it something like bee-bots or something... I call them zombie bots, because you "infect" one and it spreads it.... They couldn't be THAT hard or THAT expensive to make, after you have the basics down... Does anyone else know what I am talking about? Has anyone developed something like theses?

By toothbrush to the stars!

A concept known as a space elevator has been "doing the rounds" as a cheap way into orbital space for several decades now.Basically, a cable of some description is anchored to an orbiting mass, and vehicles climb up and down the cable to transport materials and passengers to and from orbital space cheaply and easily (in any space journey, the most expensive and dangerous parts of the journey are the first and last few kilometres).There are, technologically speaking, two main hurdles - the cable, and the vehicles.Carbon nanotube composites are a strong contender for the cable, but travelling up and down the cable takes power. Rockets are out of the question (what would be the point of the cable?). The hours, possibly days, of the journey make batteries unfeasible, and the turbulence of the atmosphere precludes the use of PV panels large enough to power the vehicles from daylight.That leaves transmitted power.So far, the transmission ideas have been electromagnetic - lasers aimed at smaller PV panels on the underside of the vehicles, or microwaves aimed at receiver dishes.Now, a new proposal suggests transmitting the energy mechanically.European Space Agency ground station engineer Dr Riise ... proposed sending power mechanically - effectively by providing a carefully timed jerk of the cable at its base.To demonstrate, he employed a broomstick to represent the cable held in tension, and an electric sander to provide a rhythmic vibration to the bottom of the stick.Around the broomstick's circumference he tied three brushes representing the climber with their bristles pointing downwards - meaning it took slightly more force to lower the brush assembly than to raise it.The vibration from the sander allowed the assembly to slide upward along the broomstick as it moved slightly downward, but grip it as it moved slightly upward. The net effect: the assembly rose against gravity straight to the top of the stick. That's a bristlebot (or vibrobot)! Dr Riise, though, calls it a longitudinal wave climber or LWC.It sounds easy enough to replicate the demonstration model, although I can't imagine how you would efficiently vibrate a 36,000km cable (I have images of damaging harmonics getting set up as the moving carriages change the effective length of the vibrating part of the cable, and shaking important bits off the vehicles).Apparently, though, the idea is being looked at by lift manufacturers for installation in the next generation of super skyscrapers.Demonstration videoBBC story

Scholarship contest idea: tennis bot

Tennis-bot serves to collect the dozens of tennis balls scattered on the court during a lesson. Using shape recognition, the robot continuously collects balls from the court and returns them to a hopper device. The tennis instructor retrieves balls from the top half of the hopper manually; the bottom half serves as a docking, recharging, and storage area for the robot. The robot's actions allow for a more continuous and productive lesson. Balls on the court are sensed by shape and color recognition cameras on the bot and are then collected with velcro hook pads. To ensure only the tennis balls belonging to the bot's owner are collected, some sort of marking may be applied to the balls. A small storage area on top of the tennis-bot holds the balls temporarily until the robot returns to the main hopper and deposits them there. The bot may also incorporate a shooting device to return balls to players. During a lesson, most tennis balls are hit behind the instructor and end up between the base line and the fence. With a line recognition camera, tennis-bot will be able to limit its search to this area. To help the robot keep track of the its position and to aid more efficient ball retrieval, an internal map system will be used.

Knex "K*bot" competitions (kbotworld.com)

Http://www.kbotworld.com/ I was bored and decided to google "Knex". What I found was very interesting. Apparently there are competitions for Knex robots that do battle with each other. As I read this I thought about how us Knex gunners at Instructables could easily dominate these competitions; because we are the kings of Knex warfare. We could have a collaboration group based around K*bots, where we will post ideas and eventually have designs for the ultimate robot. Then when the competitions come around we could find somebody who lives closest to the competition to build the robot and enter on behalf of our collaboration.But there's a catch: There are rules, an one rule states that projectile weapons are banned. But I believe there are ways around this, as the exact ruling on this goes:"Projectile weapon systems which can launch a K'NEX part clear off the K*bot are banned due to safety reasons. Any other weapons systems which the organizers deem too dangerous will also not be permitted." This could easily be avoided by fixing the projectiles to the robot. For example: My cannon could use an extremely long bullet that has rods in the back of it, preventing it from ever leaving the robot while still delivering a deadly impact. But don't forget that weapons NOT based on guns will also be essential.So what do the rest of you think?

Scholarship Robot Proposal: Garden Bot

Right now, my wife and I have a small garden(5'x7' if that). We have had good success at growing tomatoes so far. None of them have started to ripening so this would be a good test environment. The main idea would be to come up with a way to have the robot pick the tomatoes. One idea is to have a camera positioned on the tomato plants. The camera relays the information to a PC that does the visual processing. The PC sends general coordinates to the robot and the robot picks the fruit (tomatoes are really fruit). if the visual processing is not feasibility in the time frame available. The robot could water the plants at a certain time and a variable amount of water per plant. I have a couple of arduinos that can be used to aid in the functionality of the robot. If the arduino zigbee unit comes out it would be cool to use that as well.

Well I am new here and this is my first post Well I have build the arduino insect bot from the book Arduino bots and gadgets. It is in the picture. I have it working but I want to add a touch sensor and attach it to the shell. I have an idea on how to build it. I would use a small button attached to the shell with the lie going to analog A0 pin. This would stop the robot by centering the servos and giving it the ability to stop when the shell was pressed down. Now the program is here. #include Servo frontServo; Servo rearServo; int centerPos = 90; int frontRightUp = 72; int frontLeftUp = 108; int backRightForward = 75; int backLeftForward = 105; int walkSpeed = 150; // how long to wait between steps int centerTurnPos = 81; int frontTurnRightUp = 63; int frontTurnLeftUp = 117; int backTurnRightForward = 66; int backTurnLeftForward = 96; // Ping Distance Measure int pingPin = 4; long int duration, distanceInches; long distanceFront=0; //cm int startAvoidanceDistance=20; //cm long microsecondsToInches(long microseconds) {   return microseconds / 74 / 2; } long microsecondsToCentimeters(long microseconds) {   return microseconds / 29 / 2; } long distanceCm(){   pinMode(pingPin, OUTPUT);   digitalWrite(pingPin, LOW);   delayMicroseconds(2);   digitalWrite(pingPin, HIGH);   delayMicroseconds(5);   digitalWrite(pingPin, LOW);     pinMode(pingPin, INPUT);   duration = pulseIn(pingPin, HIGH);     distanceInches = microsecondsToInches(duration);   return microsecondsToCentimeters(duration); } void center() {   frontServo.write(centerPos);   rearServo.write(centerPos); } void moveForward() {   frontServo.write(frontRightUp);   rearServo.write(backLeftForward);   delay(125);   frontServo.write(centerPos);   rearServo.write(centerPos);   delay(65);     frontServo.write(frontLeftUp);   rearServo.write(backRightForward);   delay(125);     frontServo.write(centerPos);   rearServo.write(centerPos);   delay(65); } void moveBackRight() {   frontServo.write(frontRightUp);   rearServo.write(backRightForward-6);   delay(125);   frontServo.write(centerPos);   rearServo.write(centerPos-6);   delay(65);   frontServo.write(frontLeftUp+9);   rearServo.write(backLeftForward-6);   delay(125);     frontServo.write(centerPos);   rearServo.write(centerPos);   delay(65); } void moveTurnLeft() {   frontServo.write(frontTurnRightUp);   rearServo.write(backTurnLeftForward);   delay(125);   frontServo.write(centerPos);   rearServo.write(centerPos-6);   delay(65);   frontServo.write(frontLeftUp-+9);   rearServo.write(backLeftForward-6);   delay(125);     frontServo.write(centerTurnPos);   rearServo.write(centerTurnPos);   delay(65); } void setup() {   frontServo.attach(2);   rearServo.attach(3);   pinMode(pingPin, OUTPUT); } void loop() {   distanceFront=distanceCm();     if(distanceFront > 1){       if (distanceFront         for(int i=0; i<=8; i++) {         moveBackRight();         delay(walkSpeed);       }             for(int i=0; i<10; i++){         moveTurnLeft();         delay(walkSpeed);       }      } else {        moveForward();        delay(walkSpeed);      }     } } I would like to know what line of code to add to receive input from pin AO and center the servo stopping the robot.

who can i hire to make a bot for me ?

How much does one cost? how mnay TB of space do i need to hold it on my system and run it? i can only spend 299.00 a month for this and i know they have about 300 hours to make.
