OVERVIEW

Stewart Platform can offer realistic simulations at six-axis owing to the high sensitivity of linear actuators, gyroscope, and a three-axis accelerometer. With the accessible and user-friendly components, it is suitable to simulate real systems such as flight simulators, machine tool technology, crane technology, mechanical bulls, precision platform positioning such as telescopes, antennas, and orthopedic surgery.

Every unit of the Stewart platform is controllable independently with the modifiable open-source software and users can understand the effects of different controller types on the system. With the extensive courseware, users have the opportunity to learn essential aspects of robotics and easily cover controller design concepts.
