An Arduino-powered 4-axis Parallel-mechanism Robot Arm
Intro: An Arduino-powered 4-axis Parallel-mechanism Robot Arm
uArm is a miniature 4-axis parallel-mechanism robot arm, modeled after the ABB PalletPack IRB460 industrial robot arm.
It is made up of laser cut acrylic or wood parts, powered by standard RC hobby servos, and controlled by an Arduino-compatible board.
The basic design is Arduino-controlled, using 4 servos, with 4 degrees of freedom. Three servos on the base control the main movement of the arm and the last servo on the top moves and rotates the object.

uArm can be controlled with keyboard or mouse easily.
Using mouse to control uArm to play Cup Stacking via serial.
Now we are on Kickstarter, you can see more details about this robot here.

STEP 1: Materials
STEP 2: Base Assembly
Secure the two base plates via the corner holes, using four M4-10 rivets and four 32mm-M4 suction cups.
STEP 3: Inner Turntable Assembly
STEP 4: Outer Turntable Assembly
STEP 5: Shoulder Plate Servo Assembly
STEP 6: End Effector Assembly
STEP 7: Fore Arm, Back Arm & Connecting Rod Assembly
STEP 8: Install All the Parts Together to Make the Arm
1. Left Shoulder Plate to Base Assembly.
2. Back Arm to Left Shoulder Plate Assembly.
3. Servo Turntable to Right Shoulder Plate Assembly.
4. Right Shoulder Plate to Base Assembly.
5. Fore Arm to Back Arm & Connecting Rod to Left Shoulder Assembly.
6. Fore Arm Lever to Fore Arm Servo Lever Assembly.
7. End Effector to Fore Arm Assembly.
8. Electronic Module Holder to Shoulder Assembly.
The uArm robot arm is now completely assembled - Enjoy!

project that I designed, and it is similar to the robot you .
with the difference that I have made some modifications. It has structural differences compared to the robot you built."

What mobel of servo you use ? MG90s o bigger ? Is it digital or analog ?
What pwm shield you use ?

Is there no lost of electronic components or am I just not seeing them? I want to order all the parts before I start printing.

hey, coll project, i am going to build one ;)
Looks like your google drive link don't work anymore,
i get a 404 when i try to follow the link.
Do you have a new location for the parts list and drawings?
thanks

searching for plans and I found this. for an open source piece of hardware, very little has been released. when and where will the plans be available? Could you make an edition that is not in CAD so that those of us without CAD can still play with the designs?

Hello! We are university students (Colombia)
Can we get the sources files (design) for print the materials?
We hope that you can help us! Thanks!

Hi! Nice project!! Is it open source? Is it possible to download the plant? I've searched on your website, gitHub and Open Source Hardware websites but didn't find it.
Thanks!
