This Robot cleans floors very efficiently !!:)
Used in a coffee roastery as part of a larger system, but can easily be adapted for control needs. A lot of control in a small form factor.
Control any high voltage (240V, 15A) load whilst monitoring two external sensors and current drawn by load. No additional PSU needed.
Chunchunmaru is an Arduino UNO-based robot which can carry heavy loads (100kg-200kg) from one location to another.
