The document discusses the ibot Club's Roboliterate program which teaches students to build basic remote controlled robots. It provides instructions on assembling a differential drive system using materials like wood, motors, wheels and batteries. Students are encouraged to attend ibot Club workshops and sessions to learn robotics and become certified at different levels. Shops in Chennai to purchase robotics materials are also listed.

!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

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

ibot Club

13. Motor
• Electromechanical devices which
ibot Club
converts EE into ME
• Two terminals
• Can rotate in both directions
• Main Specifications:
• RPM (Rotations per minute)
• Torque (kgcm)
• Voltage (V)

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.

15. Wheels
• Normal Wheels
• Omni Wheels

17. Clamping motor-wheel to chasis
ibot Club
• ‘C’ clamps
• ‘U’ clamps
• ‘L’ clamps
• Special clamps

20. Fixing of a castor wheel
• Align castor such that chassis remains parallel
ibot Club
to the ground.

24. Why 3 wheels and not 4 wheels?
• To define a plane uniquely, you require atleast 3 points,
ibot Club
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
• Make sure Center of Gravity remains as low
ibot Club
as possible.
• Lead acid, LiPO(Lithium Polymer), Ni-Mh

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

28. How to get involved?
• Techsoc: Manual & Line-follower
• Make your own remote controlled robot.
• Involve yourself with seniors who are into
robotics
• Volunteer for ongoing projects in CFI.
• Tech fests of other colleges and institutions

29. Basic Manual Robotics Workshop
• A workshop which is the hands-on version of
today’s session
• Make your own remote controlled robot.
• On 22/09/2013 2:30PM @CFI
• A highly subsidized workshop for all IITM
students at just 250 INR.
• Bring to reality what you have learnt today.
