Saarthi: A Versatile Robot

Abstract

Saarthi is a pick and place robot which is remote controlled using WiFi. It has a camera which gives live feed. Saarthi is operated through laptop. The live feed which is obtained via camera can be viewed on laptop. Saarthi is basically used for surveillance. It monitors all the tasks. In addition to this, the robotic arm is given for picking up objects, switching on/off switches basically for handling. The main power source is solar but in case if it has to be used in shade a backup battery source is provided. Saarthi is small and a compact robot hence it can reach the places which will be difficult for humans. The central interface used in Saarthi is freedom board. All the components are interfaced together using WiFi. Saarthi can be divided into two parts software and hardware. Hardware part involves the motor driver circuitry, switching circuitry, battery level indicator and software includes the WiFi interfacing, coding of dc and servo motor. There have been other projects made using Arduino and Zigbee but the freedom board supports interfacing of more number of components. Saarthi is a soft automation based robot which boosts the efficiency of tasks performed.
