Populate the GENIE E18 Motor Control Board as shown using
the components supplied in the kit and attach flying leads and
solderless LED holders as above.
Consult the PDF GENIE E18 Motor Board for assistance.

Ensure the components and flying leads are soldered
properly.
Note: Some components in kit may vary from those shown
above e.g. the capacitors.

NOTE: Problems may arise playing video clips in PowerPoint depending on the type of player you have installed and the
location of the video clip. Two versions (.flv and .mpg) of the video are included in this folder. Double click on either to play

Manufacture the robot parts from a piece of 3mm acrylic or
foamex. Cardboard may also be used if necessary.
Above is screen cap from the 2D Design Software used with
the CNC Machine.
Use the following file found in the Sumobot folder for CNC
machining:

• Assemble the chassis parts as shown using liquid solvent cement .
• You can also refer to the solidworks drawing of the same part.

• The above is the nylon part to create the coupler for the wheels.
• Drill a piece of nylon straight through to a diameter of 5mm.
• Drill halfway through to a diameter of 5.5mm.

• Tap the lego part in with a hammer.
• The lego part can be cut to size later depending on the
size of the wheels you use.
14
• Solder in the motors. It’s not important which way the
cables are connected as this can be adjusted with the
software.

• The above is a picture of the motor attached to the wheel.
• Some hot glue can be put into the coupler to attach it to the motor
• Note how the lego part is cut to size.

The circuit board (and outer case) can be attached using
Foamex. Superglue foamex onto the front panel where the
respective holes will be. In the case of the foamex pieces for the
outer case, they should be 3mm from the edge. Use 3mm self
taping screws.

19
Insert the LDRs through the 1mm holes. Superglue them in place and
then solder them to their respective cables.
Solderless LED holders can also be used if available. This also
removes the need for Superglue.
20
Use sticky Velcro pads to attach the battery pack to the inside of the
Robot. This way the battery pack is easily removable for battery
replacement.

The motors should be glued in using the hot glue gun. Make sure the
wheels fit inside the 100 x 100 mm box.
Some masking tape can be wrapped around each motor to protect the
connections and stop them from touching.

IR Sensor
• Attach the IR sensor
with screws as shown
The square and rectangular
pieces should line up with
the slots in the plastic.

Troubleshooting
The main problems that can arise when using GENIE boards are as
follows:
1.
Connection problems caused by poorly soldered joints.
2.
USB driver not/incorrectly installed.
3.
Components incorrectly installed e.g. microchip inserted wrong way
around.
Please consult the GENIE Troubleshooting Guide.pdf located in this
folder for further information or use the GENIE troubleshooting tool.
