After some experimenting, he came up with a smooth moving robot arm with four steppers controlled from an Arduino Mega and A4988 stepper motor drivers.

Component Assembly: Connect two DC motors to the motor driver to control the left and right wheels. Attach the ultrasonic sensor to a servo motor to allow rotation and scanning of the environment.

The kit comes with Arduino Mega, which will serve as the brain, along with ESP8266 Wi-Fi Shield for remote control, a motor driver to control movement, and a battery holder. A voltage meter and power ...

Arduino boards are inexpensive and relatively easy to use devices with support for a range of sensors and motors. Now there’s an official Arduino Robot kit which makes it even easier to get started.

Ultrasonic Sensor (HC-SR04): Measures the distance to objects in front of the robot. IR Sensors: Detects the presence of a human hand on either side of the robot. Motors: Two DC motors control the ...

To try it out, I designing a pcb for interfacing an Arduino to two robot motors (scroll down here for original design), to which I have added a few more resistors to make sure all the transistors are ...
