After gaining experience from MARK-I & II the team now decided to work on with “Smart Servos”, a set of more powerful motors and that’s how Mark-3 came into existence. Following the Cad model approval, Mark 3 was created using Aluminum steel, Dynamixel (high precise motor) and a central power supply (controller for motors) which stood as high as 88.5cm. The control engineers calculated all the angles following which the coding team worked on those angles and the perfect humanoid walk was achieved. But without the sensors calibration was difficult, also we realized that the ankle design has to be much better and more like the human ankle.
