Hexapod
Product Description
Six degrees of freedom motion platform for advanced research
The Hexapod is a compact six degrees of freedom parallel robotic motion platform capable of moving up to 100 kg at high acceleration. Unlike most commercially available Stewart platforms, the Hexapod is driven by superior electrical motors which make it precise, responsive and low-maintenance.
Overview
The Hexapod is comprised of six linear ball-screw actuators driven by six DC motors. The ball-screw is based on a high-quality, low backlash linear guide with a total travel of 30 cm and is driven by a high torque direct drive motor. A revolute joint fastens the arms to each motor. For maximum safety, a motor brake control employs the Hexapod’s brakes when the joints reach their limit. Motor position feedback for all six motors is provided by optical encoders that measure the angular position of the motor shaft. An optional six axes ATI force/torque sensor can be installed on the end-effector to capture measurements of forces and torques along all degrees of freedom.
