Bought to add variety to a robot workshop for which the standard demonstrations were going badly wrong and not much time to fix them.
As it turned out, it was liked my many of the attendees but suffered badly due to running the battery down very quickly.
However, it comes with a whole variety of options, being able to walk, or waddle, use ultrasonic and IR based collision avoidance, remote control and has inbuilt speakers to play music.
In operation it looks good and makes for an interesting demonstration of the capability, only occasionally falling over but needing some tuning to get the gait to be even.
