🤖 PhoneBot Uses a Smartphone as Its Brain

The 48-centimeter robot costs about $400 without a phone. A regular smartphone provides its camera and processing, while a small onboard computer sends commands to the motors over Wi-Fi.

It walks and follows a person. After a face-down fall, it can stand up again. Its 13 low-cost servos control the legs and torso. Tests on 4 Android phones showed that the basic functions worked on all of them. The project is open for study and experiments.
