6-DOF Hexapod Stewart Platform
A parallel kinematic mechatronics concept studying 6-UPS hexapod architectures, closed-form inverse kinematics, and vestibular motion cueing filters for aerospace and automotive flight/driving simulation.
High-Payload Parallel Kinematic Motion Simulation
- ✓Provides full 6-degrees-of-freedom spatial motion with high structural load-bearing rigidity.
- ✓Distributes heavy platform payloads equally across six synchronized linear actuator legs.
- ✓Employs washout filter algorithms to simulate prolonged vehicle acceleration within physical stroke limits.
The Engineering Challenge
Problem / Objective
Serial robotic arms cannot support heavy multi-ton payloads with the high structural rigidity required for dynamic motion simulation.
