You mould a silicone finger, route three fishing-line tendons through it, and pull them with individual servos to produce bending, twisting, and extension. An OV2640 camera observes the finger and you implement a visual feedback loop to estimate its 3D pose—closing the loop between soft actuation and perception, exactly as modern surgical and industrial manipulators do.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Build\u003c\/h2\u003e\n\u003cp\u003eA continuum finger that deforms continuously along its length, controlled by tension in three longitudinal tendons. Color markers on the tip are tracked by the camera, and your Arduino code calculates servo commands to achieve a desired curvature.
