In this project, we did not add AA cells, yet it is important to add AA cells to control the microcontroller instead of fueling it with USB so the humanoid can stroll freely. **Figure 5** shows the wiring outline of utilizing the AA cells.

The Robot can be designed using Arduino UNO too. In that case, one can attach the Arduino UNO to the card body of the Robot. A smaller breadboard can also be attached at the back of the robot body. Attaching Arduino UNO and a small

They uphold a user as a partner on account of seeing obstacles close to them. Using the Bluetooth module, the user will be able to connect to the Robot and control its walking and view with the help of a mobile platform. The human operator will be able to move the Robot's head to the left and right using the platform.
