When shutting off the Robosapien it drops its arm and says something that I never could figure out. I have since learned from a friend that it is saying the word "Rosebud" (a reference to the classic movie Citizen Kane). Very cool, now that I know!
Robosapien V1 & V2
There are two sets of "knobs" on the bottom of each foot. One set is smooth (low friction) and the other have rubber/vinyl on them (high friction). I found that the rubber ones can get a bit dirty and slip. Just rubbing a pencil eraser on the rubber ones seems to improve the traction, and hence the speed, a bit.
I also found that using the second gait option the V2 moves pretty quickly on our wooden floor.
You can usually tell how Robosapien V2's batter power is holding up by the way he moves, but since he talks, why not add a function where he can tell you the status of his power source? Something like, "Power reserves at 50%".
Plus, when his batteries are critical, he could say something like, "I just can't do it... I don't have the power!"
Robosapien V2 uses a whole bunch of batteries to work. About how many hours of play time do you get from a fresh set of average alkalines?
I know certain retailers have models in different colors. How many different versions does he come in, and who sells which one?
I know that adjusting the nubs on the bottom of his fit can improve how he walks. Have you ever thought of creating shoes for his feet that you could slip on under certain circumstances. Plus, if you use the Robo outdoors, it would help keep his feet in pristine condition.
When first playing with the Robosapien V2, I had a hard time getting it to recognize my hand. That is, until I learned about the different light settings - indoor white, indoor yellow and daylight. My office has white flourescent lights, so hitting SHIFT 1/SHIFT2/SHIFT3 and Z at the same time set it to indoor white light which really helped the recognition of the robot for me!
