This is the 14core design Obstacle Avoidance BOT with L293D Shield and HC-SR04 and Servo, which is capable of avoiding obstacles using an Ultrasonic Ranging Sensor. The HC-SR04 is economical sensor provides 2cm to 400cm of non-contact measurement functionality with a ranging accuracy that can reach up to 3mm. Each HC-SR04 module includes an ultrasonic transmitter, a receiver and a control circuit. There are only four pins that you need to worry about on the HC-SR04: VCC (Power), Trig (Trigger), Echo (Receive), and GND (Ground). If you’re new to H-BRIDGE / Motor controller just follow also this link L293D / L298N.
