This quadruped robot was designed and built by one of our students right here at Edmonds College.
It has 4 legs, with 3 servo motors in each leg, which gives the legs three degrees of freedom. The servo motors used in this robot are Robotis Co.’s ax-12a series, and it controls the motors of each joint through inverse kinematics calculations at 330 times per second to give the robot the natural movement of a living animal.
The elaborate legs were designed in CAD then, after all the parts were cut out on our laser cutter, the robot’s body and legs were painstakingly assembled. Moomy III has a gyro sensor that controls the attitude of the main body in real time even though the terrain moves irregularly, and it can also be controlled manually by a remote controller connected with Zigbee modules.
