So a grad student has created a hovering robot to go running with, the idea being that it will help with setting a pace and motivation.  That is likely to work for some.

The robot is suited to all types of joggers – it has a companion mode that moves in tune with your pace and a more challenging coach mode. ”The coach mode basically tries to push you to your limits,” Mr Toprak says.

Of course, I might benefit more from a re-hacking of the robot to pursue me and give me an incentive not to slow down.  The angle of the picture already gives us a sense of menace.  It isn’t hard to see the runner as looking back in terror.  It could be a fitness revolution – running for your life every morning.
