When it falls, the robot gets back up on its own. According to the ROBOTIS page, it takes 2.8 seconds by default if it is face down and 3.9 seconds if it is on its back. The user can change this speed.

The manufacturer presents it as an affordable platform with sophisticated sensors, capable of dynamic movement, designed for research, teaching and outreach.

The ROBOTIS OP2 succeeds the ROBOTIS OP, a robot formerly known as DARwIn-OP.

The battery can be removed without switching the robot off, provided the external power supply is connected first. ROBOTIS also makes available information on the mechanics, electronics and software, including the source code.
