FETCH ROBOT

The basic principle is related to projectile motion. Where the object is deployed from the glove, the rover calculates the approximate distance, where the object might land and moves to those coordinates and collects the object in the bowl. The resistive pressure sensor collects the weight of the object and sends the equivalent ADC signal to the Tiva board. The accelerometer with the help of barometer calculates the velocity and distance at which the object will land.

This data is sent over, after processing on the first Tiva board with the help of a Bluetooth module attached to the board. The receiving end i.e. rover, running on a two-wheel driven DC motor and has a bowl mounted over it on top. The rover is also assembled with a Tiva board with a Bluetooth module to receive data from the first Tiva board. The second Tiva board is also connected to an accelerometer, which estimates the displacement to be covered in order to collect the object. A motor driver is present which is driven by a 9V battery supply.
