P
Parallel (Batteries) – Power Subsystem
A battery arrangement where multiple battery cells
are hooked up so that they provide the same voltage
as a single cell, but drain power evenly across all
the cells, thus behaving similarly to a single cell
with a very large capacity.
Pivot – Structure Subsystem
A structural component that provides a mounting
point for another component, but rather than
locking it in place, the pivot allows the attached
component to swivel or turn along a specic arc.
Potentiometer – Sensor Subsystem
An analog sensor which measures angular position.
Power Subsystem
The subsystem responsible for storing and delivering
electrical energy to the robot systems.
Programmable Mix – Control Subsystem
A feature of the Transmitter that allows the
operator to designate one master channel and one
slave channel to be used in a congurable control
mix.
R
Radio Channel – Control Subsystem
A shortened name for a radio frequency. Radio
frequencies often have long names, so they are given
“channel” designations to be used as shorthand.
75.410MHz, for instance, is referred to as Channel
61.
Radio Frequency – Control Subsystem
A designated carrier frequency for radio
transmission. Each transmitter-receiver pair
should operate on its own radio frequency, and
hence transmit data that will not interfere with
other signals in the air. The radio frequency for
a transmitter-receiver pair is determined by the
frequency crystals installed in both devices.
Glossary
Radius
The distance from the center of a circle to the
edge. This quantity is equal to half the diameter,
or it can be multiplied by two times pi to nd the
circumference of the circle.
RBRC – Power Subsystem
Rechargeable Battery Recycling Corporation.
A non-prot organization that facilitates the
collection of rechargeable batteries for recycling,
because rechargeable battery chemicals (such as the
cadmium in NiCd batteries) tend to be very harmful
to the environment when thrown in the trash.

RF Receiver Module – Control Subsystem
The Control Subsystem component that receives
and decodes FM radio signals that are sent by the
Transmitter. After decoding the signals, they are
passed on to the Microcontroller.
RF – Control Subsystem
Short for Radio Frequency, but often used to refer
to any system or component that deals with radio
transmission in any way (e.g. RF Receiver).
S
Screw, Hex – Structure Subsystem
A screw with a hexagon-shaped hole in the head,
allowing the screw to be tightened or loosened with
a hex L wrench.
Sensor Subsystem
The “eyes and ears” of the robot.
Electromechanical devices that can detect specic
things about the robot and its environment,
and communicate that information to the
Microcontroller through an electrical signal.
Series (Batteries) – Power Subsystem
A battery arrangement where multiple battery cells
are hooked up so that their voltages are added
together, thus behaving similarly to a single battery
with a much higher voltage.
