[0002] RGVs are vehicles that run along tracks, typically with switches, allowing them to turn. The tracks are typically electrified, using the track and wheels as a power source, allowing the vehicle to draw energy while traveling. However, at switches, the vehicle must deviate from the original track to a new one. This connection between the switch and track causes the wheels to lose power, rendering the vehicle incapable of driving. This has led to extensive research. Utility Model Content
