‘Namaste’ Robot To Greet Visitors Automatically

This Namaste Robot, whose mechanical frame can be made of recycled materials, monitors people within its 100cm range using an ultrasonic module.

Detecting anyone within this range, it greets the person with ‘Namaste’ symbolized by both hands joined together in traditional Indian greeting.

The robot is versatile and can be deployed in diverse settings such as business locations, parks, shops, etc, to extend greetings. Despite its primary function, the robot is designed to inspire modification for additional purposes.

For instance, envision the potential for adapting its technology for use near automatic gates at airports or garages.

Users have the flexibility to substitute the servo with various actuators for functions like automatically opening gates or doors. Alternatively, a larger servo may be attached to actuate gates or doors for automatic opening. The device is adaptable and can be repurposed for various applications.

However, our focus remains on demonstrating the sensing of human presence, activating the servo motor to move the robot’s hands, and welcoming people when someone approaches.

For the robot’s mechanical hand, users can purchase or 3D print a robot hand like the inMoov robot hand, or design a custom robot structure and body. Fig. 1 shows the author’s prototype of the inMoov hand.
