This is a well designed, 2WD mobile robot development platform. As this is a very popular platform, there are numerous example codes for it. Thanks to the 2 "geared" motors, you can easily control the speed yourself. There are several mounting holes on the acrylic plate for sensors and other accessories. An Arduino Uno with a motor shield is very suitable for the control. This kit is easy to assemble. With the user manual, you can assemble all the parts in a few minutes.
