Browser Robotics Demos

Interactive perception & planning demos, running entirely in your browser.

1. Value iteration on a gridworld coming soon
Dynamic programming solving an MDP — the value heatmap converging sweep by sweep, then the greedy policy crystallizing out of it.
2. Camera model + distortion coming soon
The pinhole model plus Brown–Conrady distortion, and the fact that undistortion is not simply the inverse formula.
3. IMU attitude estimation
Three attitude estimates from your own phone's sensors: gyro-only, accel-only, and complementary fusion. Pick up your phone and feel why fusion exists.
4. Configuration space visualizer coming soon
A 2-link planar arm in workspace, and its collision set rendered live as a bitmap in θ₁/θ₂ configuration space.
5. Particle filter localization + SLAM coming soon
Mapping, kidnapping, and relocalization — watch a particle cloud collapse into ambiguous clusters in a symmetric corridor.
6. Webcam corner detection + optical flow coming soon
Live FAST corners and Lucas–Kanade tracks on your camera feed. Point a phone at a desk, move it, watch features stick to real objects.
