Hardware assembly and testing
TurtleBot 3 arrives as a kit of parts that must be assembled. Assembly instructions can be found in the Hardware Setup section at: http://turtlebot3.robotis.com/en/latest/hardware.html.
Testing the operation of the components while you are assembling the robot is important. We recommend running the Basic Operations identified for the OpenCR board when the OpenCR board, motors, and battery are all connected. This step will verify their operation before you attach the layers for the SBC and vision sensor(s). In addition, when power is applied, look for green LEDs to light on all the boards to indicate that they are operational.
The following sections will focus on the TurtleBot 3 Burger version since that was the version that the authors evaluated as beta testers. For instructions on the TurtleBot 3 Waffle and other versions, refer to the following website: http://turtlebot3.robotis.com/en/latest/.
