ABSTRACT:
A robotic system including at least one support that supports a carriage for movement. The support may include a drive surface that is a “net shape” surface, i.e., is formed without machining. The carriage may have a traction drive that engages with the drive surface to move the carriage relative to the support. The traction drive may allow for slip at the drive surface. A bearing arrangement used to support the carriage on the support may require mainly radial forces be exerted on roller bearing elements on the carriage. A machine vision system and/or force control techniques may be used to control movement of the carriage and/or other portions of the robotic system.
