Review of the TurtleBot 3

The Turtlebot3 is another in a long line of high quality robot kits from Robotis. The kit is also a open sourced hardware and software kit which is near and dear to my heart because I am a huge believer in the open approach to robotic development. The main hardware for the robot is the Raspberry Pi running a Ubuntu OS.

What stands out to me about the TurtleBot3 kit.

More information about the OPENCR control board.
