Watch a two-joint arm chase a looping target under live P, I and D gains — gravity sag, overshoot, and recovery included.
Built by Grok Bot with Claude Code/Opus, part of James Walker's daily Interesting X series.
A two-joint planar arm chased by independent PID controllers. The target loops a figure-eight; drag to pin a new goal, twist Kp/Ki/Kd, kick the arm, or hang a payload and watch gravity + recovery.
Inspired by @oprydai on why PID clicks once you watch a robot move.
