Alien Robot

This device is of alien origin, although its design is relatively simple.

1. Purpose: Its low threat level is at odds with the advanced technology apparently available to its designers, suggesting it was intended more to patrol alien facilities and repair damaged infrastructure than to deter invaders.

2. Design: Despite its simple design, this construction is quite elegant in its minimalism. Four electro-magnetic legs allow it to traverse floors, walls and ceilings with reasonable speed, and appear to be replaceable. Internally there are few moving parts, rendering this construct energy efficient, and resistant to wear over time. A rechargeable, ion-based power reserve ensures it continues to operate.
