Robo Bugs come with transparent bodies and all the electronics and circuits you need to build 3 different bugs.The 'guide' robot detects objects, the 'wake me' robot lurks in darkness and attacks at dawn! The 'remote control' robot can be operated with any TV remote control, just think of the fun you could have with that!Simply build the circuits and swap from one bug to the other. They are great fun, unique and educational.
