“One of the challenges is to get the robot to go in a straight line. With this information, we can instruct our robot to go straight. For this project, we will only need a two (or four-wheeled) robot with appropriate motor drivers, an Arduino Uno board, and an Accelerometer and Gyroscope MPU6050.
By using a ready chassis it is possible quickly build a working model. If you buy “Robot Smart Car Kit” that includes a chassis, wheels, motors and other mechanical components, to build the robot, we will need only few additional electronics to control the motors and sensors to detect position. The whole electronic design was made based on the Arduino Uno.
At the end we add batteries and charger to power supply the robot and it will be ready for using.”
