Just added two more robots to my collection. Last year I got a Hexbug for my E-Day Demonstrations and yesterday I was in RadioShack and saw these and just had to pick them up!
The one on the left is a Spider and is remote control. The other is the Ant it uses the antennas on the front a wire loop on the back to sense an obstacle and change direction (and boy is it fast). Should make for some fun demo’s for next years E-Day!
