TROUBLESHOOTING
- Primary Test: If mBot is new, insert new batteries into battery pack and turn on mBot. mBot should beep three times. Press mBot's onboard button; pressing it once will put it in "obstacle avoidance" mode. mBot should drive forward until it encounters an obstacle; then, it will turn and drive in a different direction.

If mBot has been used, i.e. you have uploaded programs to mBot, connect mBot to a computer using the included USB cable. Open mBlock software and connect the software to mBot by clicking on the Connect menu and choosing Serial and the COM (USB) port to which mBot is connected. Once connected, click on the Connect menu again and choose Reset Default Program > mBot. mBlock will then upload the default program to mBot. Verify that mBot behaves as described above.

For a more thorough description of mBot's Default Program and troubleshooting tips if mBot does not seem to operate correctly, see TIL 4182: mBot Default Program details and troubleshooting.

-Required software: mBlock 3 (PC/Mac/ChromeOS) and mBlock Blockly (iOS/Android)
