I have a brand new mBot Ranger kit. I have followed the instructions for building the Land Raider. I then downloaded the android mBot app, and successfully operated the Land Raider using the manual mode and the virtual joy stick. However after successful operation for about 15 minutes, the next time we connected the robot with the app the manual mode begain to perform poorly. We can connect the app in bluetooth mode, and operate the robot for about 5-10 seconds before the controls freeze. at this point, after about 10-20 seconds the robot resets on it’s own. if I reconnect the bluetooth, it will work for approxoimately 5 seconds again, and the process repeats.
The app is installed on a nexus 7 tablet running 6.0
BTW: if i turn on object avoidance mode, this seems to work correctly.
Any ideas on what’s going on?
