Test Bench
Robotics concepts you can drive, not just read about. Paint a maze and race search algorithms through it, drag a robot arm around and watch it solve its own joint angles, or tune a PID loop until it stops overshooting. Nothing here is production code — just a bench to try things on.
01
Path Planning
The odometry sim, made playable. Paint walls onto the grid, pick a search algorithm, and run it — watch it explore, find the shortest path (or fail to), then trace it end to end.

Inverse Kinematics
A two-link planar arm, solved live. Drag the target and watch the analytic IK solution pick joint angles that reach it — or clamp to the nearest reachable point when it can't.

PID Control
A mass on a damped rail, driven by a PID loop. Drag anywhere to command a new setpoint, fire a disturbance kick, and tune Kp / Ki / Kd to watch the response go from sluggish to oscillating to dialed-in.
