Abstract

A self-aligning tool guide has a holder for securing a portable power tool for working on a ceiling, a lifting mechanism, and a self-balancing chassis. The holder is mounted on the lifting mechanism. The lifting mechanism has a propulsion system for raising the holder parallel to a lifting axis. The self-balancing chassis has two wheels on a wheel axis, a drive coupled to the two wheels, and a steering system. A contact sensor serves for detecting an indirect contact of the holder with the ceiling. The chassis has a brake. A controller has a mode in which the brake is activated and the balancing of the self-balancing chassis is deactivated.
