These browser-based tools let you tune controllers, move robots, and trace data structures step by step. Use them for intuition building, or just for fun.
Control Systems – Visuals & Games
Adjust Kp, Ki, Kd and watch drone altitude, servo angle, and a line follower respond in real time.
Mass–spring–damper animation. Change ζ and ωₙ and see underdamped, critical and overdamped motion.
Unit step response with automatic Mp, Trise and Tsettle calculation. Great just before exams.
Learn what setpoint and error mean by keeping a robot on its reference path.
A cart follows a moving setpoint (0 → 1 → −0.5 → 0.5). Score depends on average |error|.
Robotics Visualizers
Play with DH parameters and joint angles. See FK (angles → pose) and IK (pose → angles).
Watch a mobile robot plan paths around obstacles using different global planners.
