[Robotgroup] watching this will make you sweat

[Vern Graner]

There was a robot from SRL that was doing this at Maker Faire in San 
Mateo 3 months ago. I shot video of it and showed it to the group at one 
of the meetings. The device sent about 3 of the folks from that group to 
the medical tent with lacerations. Insanity. :P
