!bot Roboliterate Program
• !bot is launching Roboliterate program for all IITM students.
• Attend all !bot sessions, workshops, lectures and get certified as !bot Level 1 robotdeveloper/Roboliterate.
• Do a summer project under !bot and reach Level 2 and it goes on.
• Fill in your name and roll-number in the sheet that is passing around.
• NO PROXY PLEASE :P

What will we learn today?
ibot Club
We’ll learn to make a simple remote
controlled robot which can be made to move in any
desired
direction

• Spanners
• Pliers
• Screwdriver
• Wire Stripper
Materials Required
ibot Club
• Wood
• Nuts and bolts
• Motors
• Wheels
• Clamps & flanges
• Batteries
• Wires
• Switches
Basic Structure
ibot Club
• Wood (Easiest material to work with)
• Acrylic
• Aluminium
• Simplest shape to cut : Rectangular
Motor
ibot Club
• Electromechanical devices which converts EE into ME
• Two terminals
• Can rotate in both directions
• Main Specifications:
• RPM (Rotations per minute)
• Torque (kgcm)
• Voltage (V)
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.
Wheels
ibot Club
• Normal Wheels
• Omni Wheels
Fixing motor to wheel
ibot Club
Clamping motor-wheel to chasis
ibot Club
• ‘C’ clamps
• ‘U’ clamps
• ‘L’ clamps
• Special clamps

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
Placement of battery
ibot Club
• Make sure Center of Gravity remains as low as possible.
• Lead acid, LiPO(Lithium Polymer), Ni-Mh
Motor Control
ibot Club
• DPDT ( Double Pole Double Throw ) switches controls each motor.
