We have used four bar mechanism to implement forward and backward motion and upward and downward motion using only two actuators.
Stepper and Servo motors, X-Channels, Acrylic Sheet, Nuts-Bolts, Arduino Mega ADK, PS3 controller
- Design Finalization : Used four bar mechanism to actuate the shoulders efficiently
- CAD Model : Designed the CAD model in Autodesk Inventor and Fusion 360
- Simulation : Created an animation of the robot to test the design
- Manufacturing (Mechanically) : Laser cut and 3D printed the parts
- Electrical circuiting : Used stepper motor to rotate the turntable and servo motor to actuate the legs and gripper of the arm
- PS3 control : Controlled the robotic arm with a PS3 controller via an USB cable
- Mechanical Model : Good working condition
- Testing : All three servo motors are working individually
