In this study, we modified a commercially available small bipedal robot to be able to walk on the Raspberry Pi 4. First, to prepare the experimental environment, we modified the biped robot and made a stand. Then, we checked the operation of the motors. After confirming the operation of the motor, we created a program to make the robot do the walking motion. Then, using the program, we created a walking motion and conducted a walking experiment. Now that we have confirmed that the biped robot can walk, we would like to conduct research to apply the information obtained from 3D spatial recognition to biped walking by installing a depth imager on the robot.
