I used the Ultra Sonic Range Finder to help the robot detect the obstacle.
I connected the sensor to my Rpi using the bread board, 2 resistors (1k) and some male to female jumper wires. I also wrote the below code that detects the obstacle and outputs the distance from the sensor to the obstacle.
Circuit design from fritzing:
The below is the circuit design i used:
