Welcome to the resource center for the Line-Following Motor Robot Kit (MRK+Line)!

Here you will find all the reference materials that Digilent has created for this kit, as well as links to any external content we have tracked down.

The Digilent Line-Following Motor Robot Kit (MRK+Line) provides the perfect starting point for those new to robotics, but has the power to be used for advanced designs and applications as well. The MRK pairs our powerful chipKIT™ Pro MX4 microcontroller development board with a rugged steel platform and all the motors, wheels, sensors, and other parts needed to build a complete robot. When finished, the MRK+Line can be programmed to follow a dark line on a lightly colored surface. Using your MRK+Line's powerful chipKIT Pro MX4, you’ll be able to add all sorts of functionality to your robot. Add some of our extensive line of peripheral modules (Pmods™) and you can design almost anything!

Your chipKIT Pro MX4 can be programmed with either Microchip MPLAB IDE or chipKIT MPIDE. Microchip MPLAB IDE can be downloaded for free from chipKIT MPIDE can be downloaded for free from
