Arduino Jeep 2x2
This robotic car uses Ultra Sonic Sensor to detect Obstacles which are in front of it, whenever it detects obstacles then its Ultra Sonic Sensor moves in both directions Right and Left to calculates the best possible distance to move freely.
Bluetooth controlled car is controlled by using Android mobile phone instead of any other method like buttons, gesture etc. Here only needs to touch button in android phone to control the car in forward, backwardd, left and right directions. So here android phone is used as transmitting device and Bluetooth module placed in car is used as receiver. Android phone will transmit command using its in-built Bluetooth to car so that it can move in the required direction like moving forward, reverse, turning left, turning right and stop.
