Abstract
A rotary drive device has a fluid-actuated rotary drive with a drive housing and a drive unit which is rotative relative thereto. The drive unit includes a drive shaft and a pivot piston, non-rotatably arranged thereon, separating two drive chambers from one another. For controlling the fluid-actuated rotary drive, a control valve arrangement including at least one electrically actuatable control valve is provided, which is attached to the drive housing and in this way is combined with the rotary drive to form a drive assembly that can be handled as a single unit. Furthermore, a robot arm is proposed, which has the rotary drive device as an arm joint connecting two arm members.
