About ROBOTIS OP2 (DARwIn-OP2)
The ROBOTIS OP2, also called DARwIn-OP2, is a small humanoid platform for research and education and the successor to DARwIn-OP. ROBOTIS describes the upgrade as mainly a large increase in computing power. The OP2 uses a dual-core Intel Atom N2600 PC with a CM-740 sub-controller; its RAM and storage are user-replaceable.
ROBOTIS's product specifications list a height of 454.5 mm, a weight of 3 kg and 20 actuated degrees of freedom: 12 in the legs, 6 in the arms and 2 in the neck. The same page gives a default walking speed of 24 cm per second, an 1,800 mAh battery and about 30 minutes of operation.
The e-manual says the battery can be changed without shutting down the robot when external power is connected first. ROBOTIS's current platform index explicitly marks OP2 as discontinued, and the OP3 is its successor. A reliable public release date was not found.
