Just what we need. Robots that get their energy by digesting mammals. What could possibly go wrong with that??
This is a coffee table that doubles as a mouse trap.
Crumbs are placed on the table to encourage mice to climb up the hole in the far-right table leg.
When the mouse stands on the trapdoor in the centre, sensors open the door and it falls into the microbial fuel cell.
The digested mouse generates the energy to power the trap door, sensor and an LED graphic display on the front of the table.
