Motion-Control Rig V3

An eight-axis camera motion-control system, designed and built from scratch — together with my father — out of wood, aluminium, pillow-block bearings, and a second-hand slewing ring.

The axes: base pan on the slewing ring, tilt pivot, a 1.2 m linear slide along the arm, a second pan at the arm's end, a second tilt on the carriage, camera roll, a travelling counterweight, and a 1 m X-dolly under the whole machine.

An ESP32 with TMC2209 silent stepper drivers handles motion; a Raspberry Pi 5 runs the inverse kinematics, so the camera flies through coordinated moves that repeat exactly — the foundation for multi-pass miniature photography.
