Abstract: imagine a robot that follows you and does work under your guidance. This is Helping Hand. It has a robotic arm that symbolizes human hand thus its name Helping Hand. The robot has two parts, the ultrasonic follower part and an advanced computing part which has the robotic arm. The Ultrasound follower part detects the direction and distance of a human source which emits ultrasound. It is powered by an Atmega328 based Arduino Uno. The advanced human detector part consists of a Camera and a robotic arm both of which are under a computer on chip such as Raspberry Pi 3. The overall design consists of a base ultrasonic follower on a rover platform and an advanced computing part laid upon the base. It follows a suitable ultrasound emitter with a human and along with image processing the exact distance, direction of movement is found and a host of other features like gesture control can be added. When the robot is start up, it suitably follows the human, when he stops, the robot looks around it to find for objects and if found, it goes near objects to pick up and keep it on its base or a suitable platform, it then searches for the human, it continues to follow until the human stops again and shows his hand gesture, which tells the robot which side the object has to be placed back. After placing it again starts to follow the human.
