Design and fabrication of active tilt-stage for laser rangefinder
… tilt-stage that will carry the UTM-30LX, a laser rangefinder sensor (LRF) that is fabricated to scan in a 2-D plane, was determined by analysis. The LRF will be mounted with the tilt-stage on the PIONEER 3-AT (P3-AT), a robot designed to be mobile in rough-terrains, such that autonomous navigation …
