User Ray Foss published the tool, called \"Auto-Charge Tracker,\" on GitHub. The system uses a webcam to track the controller and the Steam Controller Puck, then vibrates the controller's four haptic motors to move it across a desk until it snaps into the charging station via built-in magnets. Foss was inspired by an earlier app from developer Very Lazy Pixels that turned the Steam Controller into a remote-controlled car using keyboard inputs. Foss combined that vibration-driving technique with camera-based positioning. In a video posted to X on June 25, the controller is seen gliding toward the puck and connecting. Foss warned that the coating on the controller's contact points may wear off from prolonged vibration on a hard surface. The Steam Controller, released on May 5, sold out on its launch day. The app is free to use and requires a webcam and a PC running Steam.","whyItMatters":"The mod turns a standard accessory into a proof-of-concept for autonomous peripheral docking using only the controller's existing haptic motors and a webcam.","webCardHtml":"\u003cp\u003eFoss\u0026#39;s \u0026#34;Auto-Charge Tracker\u0026#34; is a browser-based web app that requires no additional software beyond a webcam and a PC running Steam. The user places the Steam Controller and the Steam Controller Puck on a desk, films them from above, and marks their positions in the app. The controller then uses its four haptic motors to vibrate across the desk toward the puck, which has strong built-in magnets that snap the controller into the correct charging position.\u003c/p\u003e\n\n\u003cp\u003eFoss said he was inspired by a web app from developer Very Lazy Pixels, which turned the Steam Controller into a remote-controlled car using keyboard inputs to control the vibration function.

Valve designed those motors for feedback, not desk travel.","threadsPost":"A modder turned the Steam Controller into a self-driving device using its own haptic motors.
