mBot provides three preset modes:
The infrared remote control mode is the default mode, and you can use the infrared remote controller or the on-board button to switch between the modes.
How do I know which mode mBot is running in?
The color of the LED on the main board indicates the mode.
White: infrared remote control mode
Green: obstacle avoidance mode
Blue: line following mode
Obstacle avoidance mode
In obstacle avoidance mode, mBot moves and avoids obstacles autonomously.
Infrared remote control mode
A special infrared remote controller is included in the package. You can use the remote control to control mBot, such as its speed and direction.
Line following mode
In line-following mode, mBot moves autonomously along the black lines on the map.
