Not everyone likes cockroaches. That is not always bad news. You could always use RC cockroaches to pull pranks on others. The Roachbot is a creepy looking robot that looks somewhat like the real thing and can be controlled using your iPhone or iPad. You just need to download its companion app to start controlling the robot.
The app gives you many ways to control your robotic cockroach. Roachbot does look quite realistic. This is available for $37. A nice toy to tease your friends with.
