I have revamped the control system of this 20-year-old 5DOF articulated robotic arm with TP controls and programming interface integrated.
The ball and beam system is laboratory equipment with high nonlinearity in its dynamics and PID control.
The ball and beam system is a popular textbook example in control theory and nonlinear dynamics.
Balancing two-wheel robot with an onboard camera. When different colors are seen, the robot executes different trajectories.
