Low Friction Pneumatic Actuators for Accurate Robot Control
Published January 01, 1986 by Institution of Mechanical Engineers in United Kingdom
The performance of two different types of pneumatic cylinder incorporating air bearings is compared with that of a cylinder using conventional seals at the end plates. Friction levels are reduced considerably if a PTFE piston seal is used in addition to the air bearings. This should enable a high accuracy pneumatic position control system to be developed for robot actuators.
