A selfpropelled robot has started cutting up the concrete of the tow paths along the Panama canal as part of its ongoing tow path replacement programme. The Conjet Robot 363 will cut out the tow path which supports track for locomotives pulling ships through the canal between the Atlantic and Pacific Oceans. The Panama Canal Authority will use the robot to remove worn out concrete supporting the tow track system at Gatun Locks on the Atlantic side of the 80km canal. The robot reaches across the track rather than resting on it, so its arm can move out of the way to allow trains to pass every 20 minutes.
