Description: This minimally designed sculptural robot is entirely solar powered, so it's autonomous in energy acquisition.  It is also autonomous in control since it employs a simple open source 1381 solar engine circuit.  As with all my work, this sculpture is designed with open source circuits and off the shelf technologies (including o-rings and hose clamps).
