In celebration of National Robotics Week, the Vecna Cares Charitable Trust will host its second-annual human and robot race — in Cambridge on Sunday, April 10 at the Vecna Technologies office (36 Cambridge Park Drive, near Alewife T Station).  The Kids’ Run will be at 9:45AM, followed by the (adult) Human 5K at 10AM and the 100-yard Robot Race at 11AM.  Humans may register online for themselves and/or their robots, and anyone may also donate online.  The Kids’ Run is free.  Fees for adults and robots are $30 per person before April 7 or $35 per person on race day (minus $5 per person for those on teams or minus $10 per person for those in school groups).  All participants are invited to the post-race party.  Net proceeds will go to the Vecna Cares Charitable Trust (video).  For more information, contact Seth Reddy at 617.674.8248 or robotrace5K@vecna.com.
