Overview
The Digilent Remote Control Robotic Development Kit (RDK-Remote) is an ideal platform for robotic
applications. When used with any of several available Digilent embedded controllers and our
extensive line of peripheral modules (Pmods), countless designs can be implemented, from basic
experiments through more advanced systems.
Included parts:
PmodJSTK
PmodRJ45F
PmodRJ45M
two PmodHB5 2A H-bridge motor amplifiers with attachment clips
Cerebot 32MX4
Ethernet cable
rugged metal platform with holes on ½-inch center
rugged metal motor mount
two 1/19 ratio motor/gearbox drives with ABS plastic wheels (1/53 gear ratio motors are
available)
rugged plastic wheels and drag button
AA battery holder (holds four AA batteries)
all wiring and assembly hardware included
Functional Description
The rugged steel components have holes on ½-inch centers allowing Digilent circuit boards and other
vendors’ products to be easily attached.
The following tools are recommended for robot assembly:
regular and small Phillips head screwdriver
small wrench
pliers
wire stripper

Example Assembly
The following example assembly makes use of the RDK_RemoteControl reference design, available
at www.digilentinc.com:
1. Take out the metal platform and place the metal motor mount on the top right side. Attach
screws accordingly.
2. Attach motors to the metal motor mount with miniature screws.

3. Attach the battery holder to the metal platform (below the motor mount) using the sticky
Velcro.
4. Attach the Pmod clips to the metal platform on either side of the battery holder.
5. Attach the drag button to the metal platform, below the battery holder.

8. Compare the Cerebot 32MX4 board to the picture below. Note that the blue shorts are
attached to each jumper as depicted. Remove the rubber feet from the bottom of the corners
of the Cerebot32MX4. Attach the standoffs to the board using the corresponding mounting
screws. Mount the Cerebot 32MX4 board to the top side of the metal platform. Be careful not
to cross thread screws while mounting the Cerebot 32MX4 board.

9. Connect the two PmodHB5 modules to port JD on the Cerebot 32MX4 board using the 2x6 Pin
to dual 6 pin cable. Use the marker on the cable connector to ensure that pin placements are
in alignment when connecting the boards.
10. Strip ½-inch of insulation from both ends of all red and black 22 gauge power wires.

11. Route power wires from each PmodHB5 to the J18 power connector on the Cerebot 32MX4
board, noting ground and voltage connections.
12. Attach the power cable from the battery back to the J14 battery power connector on the
Cerebot 32MX4 board.

13. Connect the PmodRJ45M to the top JB Pmod header, and connect one end of the Ethernet
cable to the PmodRJ45M.
14. Connect the other end of the Ethernet cable to the PmodRJ45F, and connect the PmodJSTK
to the PmodRJ45F.

15. MPLAB can now be used to program the RDK_RemoteControl reference design to the board.
For more information on how to program the Cerebot32MX4 using MPLAB, see the
Cerebot32MX4 LED Demo project at www.digilentinc.com. Note that running the reference
design that turns the motors requires that the power select mode jumper J12 be shorted to
External Power.
Once the board has been programmed with the reference design, movement on the joystick
should cause the robot to move in a similar fashion. Orient the Remote Control RDK Kit as
shown below.
