14. Motor Parts
ibot Club
GEAR BOX MOTOR
SHAFT
• Shaft: It is where we attach
wheel or an other mechanism
• Gearbox: This is to reduce the
basic rpm of the motor to the
desired one.
• Motor: High RPM motor
which is then reduced using
gearbox.

24. Why 3 wheels and not 4 wheels?
ibot Club
• To define a plane uniquely, you require atleast 3
points, but if we have 4 points we need to make sure
that all the four points lie in a plane.
• Hence, 3 is the preferred choice. We need suspensions
incase of 4 wheels

25. Placement of battery
ibot Club
• Make sure Center of Gravity remains as low
as possible.
• Lead acid, LiPO(Lithium Polymer), Ni-Mh

26. Motor Control
ibot Club
• DPDT ( Double Pole Double Throw ) switches
controls each motor.
