Improved Self-Balancing Tool Guide

A self-aligning tool guide includes a mounting for fixing a hand-held machine tool, a lifting mechanism where the mounting is mounted on the lifting mechanism, and a self-balancing chassis that has two wheels on a wheel axle, a drive coupled with the two wheels, and a steering system. A lateral deflection of a center of gravity of the lifting mechanism relative to the wheel axle is detectable by a center of gravity sensor and the steering system is configured to control the drive to output a torque counteracting the lateral deflection. A self-balancing member is mounted on an upper portion of the self-aligning tool guide and the self-balancing member delivers an additional torque for balancing the self-aligning tool guide.
