The MiP robot was released in August 2014. MiP is an interactive robot toy designed for kids. The robot responds using hand sensory technology, as well as a downloadable app that allows MiP to drive, dance and play games.
The sensor may be obstructed, make sure that the surface of the robot is clean. If this is not the issue try the solutions in the "Will Not Respond to Hand Commands" section on the troubleshooting page. Here is the link: WowWee MiP Robot Troubleshooting
