Abstract

The roller/bar friction-drive is an example of a high-precision rectilinear actuator. The roller/bar friction drive offers control advantages of low backlash and dead-band due to elastic averaging within the Hertzian contact region. It also offers simplicity, both of initial design and extensibility to longer ranges (as high as of the order of meters) while incurring only marginal effort/cost in design and implementation. Furthermore, the roller/bar friction drive has not been employed extensively, this is probably due to uncertainty over issues of l
