Robotic Arm
A desktop robotic arm built joint by joint. You will wire and calibrate each servo, learn how a multi-axis arm converts angles into position, and finish with an arm that can pick up, move and place objects under your own code.
What you’ll learn
- Multi-servo joint control and calibration
- Forward kinematics — turning angles into position
- Gripper control for picking and placing
- Programmable movement sequences
