I was that kid in the 80s that played with robotics toys. (My favorite was the Armatron from Radio Shack). When I grew up, I was somewhat disappointed to see that the biggest opportunity in robotics was to make robotics toys to inspire the next generation. These days I make robots that solve real business problems. However, there is an obvious and tempting market for selling them as entertainment/education robots instead. But I'm deliberately trying to make real robots that solve real problems. Sometimes, though, I feel that people are more interested in "useless" robots.
