connector. Connect your master power switch to the other
end of the fuse. The (currently) free wire coming out of the
master power switch will be the main connection point for
your negative wires. The positive cable coming from your
battery connector will be the main connection point for the
Here’s what should plug where:
GND- cables from speed controllers
Negative 24V fan cables from speed controllers
Negative side of the LED circuit
GND+ cables from speed controllers
Positive 24V fan cables from speed controllers

The battery plugs into the battery connectors. Power
flows from the negative terminal of the battery through the
fuse (which will break if you have a short circuit), and then
through the master power switch. If the master power
switch is on, electricity will flow through the switch into the
speed controllers (which, in turn, power the motors), then
into the fans (which cool the speed controllers), and finally
into the LED circuit, indicating that the robot is powered on.
This is the main electrical system of the bot, but there’s still
a bit more to do.
Next up, insulate the hell out of everything. Look at
EVERY connection and make sure that it has the correct
polarity, the wire is going to the right place, the connection
is VERY secure, and that the connection is nowhere near
anything that might short it out. (Remember: This robot
could potentially be thrown in the air and come crashing
down onto a hardened steel floor. Make your connections
secure the first time.)
BINDING THE TRANSMITTER AND RECEIVER
Binding is the process of linking the transmitter and
receiver so they talk to each other and are able to filter out
interference. To bind your transmitter to your receiver,
follow these steps:
1) Disconnect the receiver cables from the speed
2) Insert the bind plug into the “BAT” terminal.
3) Insert the receiver battery into any free port on the
4) At this point, the LED on the receiver should be
flashing which means it’s ready to bind. Pull and
hold the trainer switch in the upper left-hand corner
of the transmitter as you switch on the transmitter.
5) The flashing LED on the receiver should go solid
after a few seconds, meaning the binding process is
complete. Now, unplug the bind plug and battery,
and turn off the transmitter.
FINAL SAFETY CHECKS
It’s almost time to power the bot on for the first time.
Go through every electrical connection at least twice more,
making sure that every wire is where it should be,
everything is secure, and no wires are mis-colored. Ideally,
you should perform your first test outside, since there is
always a possibility of a battery exploding (and you want it
to be as far away from anything flammable as possible).
1) Raise the bot off the floor so no moving parts can
touch anything. Make sure it’s secure — your
ComBot will have some torque and may jerk around
despite the wheels not touching the ground.
2) Turn on the transmitter first.
3) Plug in the receiver battery, and wait for the solid
light indicating communication.
4) With the master power switch OFF, plug your
battery into your battery connectors.
5) Make sure your transmitter joysticks are in a neutral
