4WD Mini-robots explore city tunnels

Robots have been used under a Somerset, city to see if a network of tunnels can help reduce the risk of flooding.



The robots were sent out by the Environment Agency in an exploration of hundreds of tunnels beneath Wells.

Small cameras are mounted onto a four wheel drive chassis to record the state and routes of the passageways.

So far none have been lost to CHUDs.
