Visual Servoing: Using Eyes to Guide a Robot's Hands
Visual servoing is like how you reach for a cup: your eyes guide your hand. A robot uses a camera to continuously correct its motion toward a target, closing the loop between seeing and doing. It's key for robotic arms, drones, and surgical bots.
Visual servoing is the principle of using eyes to guide hands. Instead of a pre-planned path, a robot uses real-time video to measure its error relative to a target and continuously adjusts its movements. This is fundamental for robotic arms grasping moving objects or drones landing on charging stations. The biggest footgun is assuming perfect perception; bad camera calibration or lighting changes will cause inaccurate movements.
