3.2 Components Required
1. Chassis:- Chassis is a supporting frame or structure of any vehicle (car).It can also be known as a frame which bears all the stresses of the vehicle.Here,we will use chassis as a part of a car which will support the car and bear all the weights.
2. BO MOTOR x 4 :-
“A motor is a machine that converts electrical energy to mechanical energy.” BO (Battery Operated) light weight DC geared motor which gives good torque and rpm at lower voltages. This motor can run at approximately 150 RPM when driven by a single Li-Ion cell. In another word, the electrical energy is a “battery” and the mechanical energy is the “rotation.”
3. Jumper Wires :- Jumper are the connecting wires with the connector at each end used to connect different components on breadboard or any other testing boards.
4. Motor clips or holder and Screws & Nuts:
These are used to attach the motors on the chassis.
5. Arduino UNO:
Arduino is an open-source electronics platform based on easy-to-use hardware and software. Arduino boards are able to read inputs – light on a sensor, a finger on a button, or a Twitter message – and turn it into an output – activating a motor, turning on an LED, publishing something online. Arduino works like a CPU(Central processing unit), it is a brain of the whole projects.
6. Motor driver:
Motor driver is an interface between motor and the control circuit.Motor works on high amount of current but the controller circuit works on low amount of current.So, for this Motor driver are used,they take a low current signal and convert it into high current signals to drive the motors.L293D is a motor driver which drive DC motor in either direction.It means you can control two motors with a motor driver module.

7. Ultrasonic Sensor:
Ultrasonic sensors work by sending out a sound wave at a frequency above the range of human hearing. The transducer of the sensor acts as a microphone to receive and send the ultrasonic sound. Our ultrasonic sensors, like many others, use a single transducer to send a pulse and to receive the echo. The sensor determines the distance to a target by measuring time lapses between the sending and receiving of the ultrasonic pulse.
