Balancing two-wheel robot with an onboard camera. When different colors are seen, the robot executes different trajectories.
The ball and beam system is a popular textbook example in control theory and nonlinear dynamics.
PID control on Arduino with LabView to stabilize a ball on a beam.
I have revamped the control system of this 20-year-old 5DOF articulated robotic arm with TP controls and programming interface integrated.
Exploiting the persistence of vision quirk of the human eye, myGlobe uses a single strip of 25 LEDs to draw any image in thin air.
