A modular robot body links its head, arms, joints, and wheel drives while bringing sensing and connectivity together under central processing. The main processor coordinates the robot’s body-level behavior, the sensing that tracks the robot's movement and surroundings, and the wireless links to phones, apps, services or health monitoring devices. Processing runs the behavior and the on-device AI, sensing provides orientation, obstacle detection and awareness of people nearby, and connectivity keeps the robot in touch while personal data stays protected.
