Modular Arduino 4WD Monster Car
Print Profile(1)
Description
This is a 4-wheel drive Arduino Monster Car built as a modular and beginner-friendly robotics platform.
It is designed for obstacle avoidance, Bluetooth control, and general robotics learning.
The robot features a modular front mounting system, which means you are NOT limited to using an ultrasonic sensor. The front can be redesigned or customized for different sensors and mechanical attachments.
The two-level chassis design keeps electronics separated from motors for better weight distribution and stability.
