After two years of building robots out of cardboard I tried to build one robot out of LEGO® bricks. This is an introduction how to make your own robot. Building the chassis was straight forward. All you need are some special bricks from LEGO® to link the DC motors with the bricks. To find the right bricks to screw down the four yellow gear motors was not easy. This took a couple of weeks as I had no LEGO® bricks at home and I had to order them from an online shop which sells used LEGO® bricks separately.
The solution I found is surprisingly stable and I started to mount some additional bricks on top of the chassis to hold the Raspberry Pi camera, the battery pack, L298N motor driver, the Raspberry Pi 2 and some additional electronic components.
Robot build of LEGO® bricks
This is a very early picture from my first robot built of LEGO® bricks. The chassis is very cool and easy to build out of the bricks. With some additional bricks it is easy to design a nice body for the robot.
The next pictures shows the robot wiht the WIFI USB modul and the camera mounted on top of the robot. All you need are some bricks and the special bricks to screw down the DC motors.
The e-book “Robot Car” describes the building of the robot car with all the information and programs you need to build your own robot. The e-book is available here: Robot Car – eBook
This is a picture from above my robot. It shows all the electronic components used to build the robot car.
Robot Car eBook
My eBook is a step by step guide and explains everything you need to build your own robot based on a Raspberry Pi as the brain of your robot. The eBook is available here:
Robot car video
I made a few videos of my robots and uploaded the videos on YouTube. The video below shows the first model build of LEGO® bricks by a friend and his boys.
