Stewart Platform

6-DoF sophisticated motion system for robotics and controls
ACROME Stewart Platform is a parallel robotic system, could be used for advanced robotics concepts in academia and various applications in industry. It has a default configuration for payload, size and user software.

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.

Flying is a movement that human beings cannot do under natural conditions, but they can do with the tools they have invented. Vehicles such as helicopters, and airplanes, are produced for such situations. Although it may seem easy to move at first glance, there are too many factors to be controlled by the pilot to operate/fly these vehicles.
