DARWIN-OP which stands for Dynamic Anthropomorphic Robot with Intelligence– Open Platform is a miniature- humanoid robot platform with advanced computational power, sophisticated sensors, high payload capacity, and dynamic motion ability developed and manufactured by Korean robot manufacturer ROBOTIS in collaboration with Virginia Tech, Purdue University,and University of Pennsylvania. DARWIN-OP has twenty degrees of freedom [20 DOF] each controlled by a DYNAMIXEL MX-28T servo motor. The MX-28T has a stall torque of 24 kgf·cm (at 12 V, 1.5 A) and a 360 degree range of motion.
With the release of the ROBOTIS OP2, the name of DARwIn-OP has also changed. 1
DARWIN-OP's main purpose is for research and programmers in the fields of humanoid, artificial intelligence, gait algorithm, vision, inverse kinematics, linguistics, etc... It is also supported by $1.2 million NSF grant and has been distributed to over 14 institutions already.
DARWIN-OP is also the winner of the Kid Size League in the RoboCup 2011 2012 League, and 2013 League.
