I was able to get a first hand look at the OP3 during ROSCon 2017 and IROS 2017 in Vancouver B.C.
So the first question I asked was why a new robot? What has wrong with the OP1 and OP2? I got some great answers from the robot engineers at Robotis. The number one and most important improvement was to allow the robot use ROS (Robot Operating System). This drove almost all of the improvements and upgrades to the OP platform. The other main improvement was to upgraded the robot to use the new Dynamical X-series of servos.
Below are some unedited videos of the robot in action.
