Introduction: An Arduino-powered 4-axis Parallel-mechanism 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.
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
