Mi Robot Builder Rover

For a toy, it has some pretty robust specs:

• 32-bit ARM Cortex Mx processor at 108MHz max
• 32Mb Flash internal storage
• Bluetooth connectivity and 2.4GHz wireless support
• 11.1V/18.3Wh lithium battery providing up to 12 hours of standby power
• Two brushless servo motors
• Built-in gyroscope
• App control with support for Android 4.3 and above, iOS 6.0, and above

This isn’t the kind of project you slap together in a few minutes and then send ripping around to give your cat something to chase. Children under 12 may find it frustrating to work with alone and even adults can get exasperated looking for the tiny pieces.
