The build relies on an Arduino Uno as the brains. It’s equipped with an L293D motor driver shield to run two DC gear motors which drive the walking assemblies.

The Arduino has been used for many purposes, and “shields” are available to make many common tasks easier. However, [Nick] wanted a stackable motor driver shield, so he build one hims… ...

It's run by an Arduino UNO board, and includes several key components: four gear motors with wheels for moving the car, four LEDs for signaling the active status of each motor, a motor driver for ...

Upon sensing an obstacle, it then sends a signal to the Arduino UNO, which, in turn, triggers the motor driver (connected to two DC motors) to move the box either forward or backward for a few ...
