MotionSIM

6 DOF Motion Platform

This is an industrial/research grade 6 DOF Motion platform (Stewart–Gough Hexapod) which provides simultaneous, high-dynamic motion in all 6 degrees of freedom — Surge (X), Sway (Y), Heave (Z) and Roll (θX), Pitch (θY), Yaw (θZ).

Driven by six electric roller-screw servo actuators, it reproduces real-world motion cues with low latency for flight, driving and marine simulators, VR/entertainment rigs, vibration testing and hardware-in-the-loop research.

Travel range is ±281 mm in surge/sway and ±254 mm in heave, with ±24° of rotation, peak acceleration beyond 0.8 g and a motion bandwidth up to 10 Hz, supporting payloads up to 1000 kg (1500 kg max).

The simultaneous motion is achieved due to the fact that all the actuators work in parallel - sharing the load to ensure rapid pose change and high stiffness. A real-time controller running classical and optimal washout (motion-cueing) algorithms maps simulator dynamics into the platform envelope at a 1 kHz servo rate.
