Data Sheet

Overview
The DFRobot 4WD Arduino Mobile Platform provides a 4 wheel drive system complete with 4 DC
Motors. The DC Motors are not your typical robotic actuators. Rather, they are basic DC motors that
can be picked up at your local Radio Shack for a few bucks a pop!

Assembly and Construction
To make this part as easy and straight forward as possible we have recorded a multi-part step by step
video of how to assembly and work with the DFRobot 4WD Arduino Mobile Platform.
Support
We gave DFRobot a 4 for support. One of the main reasons is because we have never needed any with
their products. Imagine that. A product that does not require support. We would have given them a 5 but
we did not have the instructions included in the kit. Even though the kit was easy to build - we think it
would have been a good idea to have the assembly instructions included. More specifically when it
came time to wire up the unit to the DFRobot Arduino Romeo microcontroller. It was straight forward
for us to assembly - but may not be to the typical consumer.
