Desk Pet USB Tankbots
With Desk Pet USB Tankbots you can control a robot with your iPhone or Android phone and it will navigate a maze all by itself in automatic mode. That means that all of that clutter on your desk can finally be put to good use.
The tankbot detects obstacles and can navigate around them easily. Set up a maze on your desk and the Tankbot will traverse it. If you want to control it, just attach the Universal Remote to your smartphone and use the free Desk Pet app to drive your TankBot.
