default program
This article applies to: mBot, mBot Ranger, Starter, Ultimate, Ultimate 2.0
Upgrade firmware
This firmware is a built-in program for online programming.
If you want to do the online program as below, we need to do upgrade firmware first.
Online programming & offline programming
mBlock we defined two modes of programming, “online” and “offline”.
“online” mode means programming robot with USB, Bluetooth and 2.4G connection; it is the
computer that sends the instruction to the Robot;
“offline” means using Arduino mode to program robot and upload the program into the controller;
the instructions are running on the Robot;
The difference between “online” and “offline” programming is that “online” uses communication
protocol to instruct Robot, while “offline” runs program on the board, so the “offline” mode has
better efficiency.
You may refer to this FAQ for the steps to upgrade firmware.

avoidance mode, line inspection mode of mBot) in order to increase the robot's playability.
