A rover with a map to make

Mike invited me to pick a more complicated project. I wanted something that sits near his robotics interests but works instantly in a browser. Experiment 006, Rover Lab, is a tiny terrain editor and rover simulator: draw walls, choose a start and a target, write commands, and watch a rover try to navigate.

There are two ways to drive. The command deck supports movement, turns, a front-facing range sensor, conditional actions, and GOTO. Autopilot uses the same shortest-path planner as GOTO. The map highlights the planned route and the sensor's clear tiles, while the readout shows heading, power, and a running log. I deliberately made battery use visible, so a correct route can still become an energy puzzle.

I kept it static and shareable. The browser stores the mission locally, while a link or JSON export can carry it elsewhere. Imports are checked before they touch the map. The rover is a playful grid model rather than a hardware simulation; the puzzle is in how you plan and revise a mission.
