The new HEX150 RC Hexapod from Aerotech impresses with its excellent precision mechanics

Written by: Aerotech Ltd | Published:

Aerotech, manufacturer of high-performance motion control and positioning systems, is launching a new hexapod, for quality assurance applications. As a smaller brother to the HEX500 and HEX300, the HEX150 RC with a diameter of 150 mm complements the existing product family diameters of 500 and 300 mm.

The unmistakable advantage of the multi-axis, parallel kinematic hexapods is precise positioning freely in all directions. With a central movement distance of 135 mm, this allows the multi-axis system to be used flexibly for a wide variety of applications, for example in measurement and testing technology.

The new 150 series hexapod with its high load-bearing capacity coupled with large movement distances and high positioning speeds of 50 mm/s leaves nothing to be desired in the application specification. The high-precision positioning system impresses with its excellent mechanics: Extremely stiff drive legs with brushless, slotless AC servo motors not only ensure ultimate performance and a long service life, but also maximum precision in the submicrometre range. The AC servo motors are connected directly to the ball bearing spindle, which guarantees high drive rigidity. According to the manufacturer, the HEX150 RC is currently the most precise hexapod on the market.

Simulation in free space

Due to the complex kinematics, the control effort of a hexapod should not be underestimated. Aerotech counteracts this with the innovative control platform A3200, resulting from years of experience with demanding kinematic applications. The integrated, intuitive simulation software “HexGen Hexapod” enables simple programming and control of the hexapods in any user-defined coordinate system. The user can visualize and simulate the available work space in order to carry out collision observations. In addition, the user can also select pre-configured models directly from a stored library with standard designs.

In order to be able to simulate the entire work process, the AS3200 accesses the open platform Coppelia Robotics V-REP via a simulation interface. Complete automation processes can be simulated on this platform, and the required robot actuators, linear or rotary tables and tools can be assembled in a 3D environment.
