The basic concept is simple enough and has been around for years, perhaps decades. Mount a button battery and tiny pager/cellphone vibrator motor on the back of a cut off toothbrush head and you have a cute robot insect that will scramble around providing hours of amusement and entertainment.
Innovation First took the concept to another level, refining the design and adding a lot of character and personality to the robots creating their wildly popular Hexbug line of robotic toys. While the issue of whether or not the Hexbug robots actually inspire kids to get into engineering and science career paths, the toys are pervasive and seem to be on toy and electronic shop shelves everywhere.
RoboGames champion Nick Donaldson seems to live, eat, sleep, and breathe robots. He consistently wins a raft of medals across a wide range of different categories during the annual robot gathering, and has designed all types of robots including LEGOs, multi-legged rescue bots, and even a few that might be difficult to categorize. Now, thanks to almost 10 years of hard work, dedication, and a little luck, it looks like one of Donaldson's cutest robot creations, a robot monkey, just might become the hottest selling robot toy in the US this Christmas.
