The eagerly awaited "Winter Workshop" held during December is a learning and teaching experience for youngsters whose innovative ideas never cease to amaze. Every year's Winter Workshop aims to further robotics not only as a hobby but also delve deeper into the areas of robotics as a research oriented goal.
"The hands-on Winter Workshop has been christened the most productive period in fresher life."

LOCOMOTION
This system gives our machine the ability to move forward, backward and take turns.
It may also provide for climbing up and down.
The concept of locomotion invariably needs rotational motion.
This involves conversion of electrical energy into mechanical energy, which we can easily achieve using electrical motors.
The issue is to control these motors to give the required speed and torque.
Q. Which famous artist is known to have drawn designs of an armored humanoid?
Leonardo Da Vinci
PARIS, France
Ecole Normale Superieure de Techniques Avancees
DIFFERENTIAL DRIVE
Most commonly used
Simplest and easiest to implement
It has a free moving wheel in the front accompanied with a left and right wheel
The two wheels are separately powered
When the wheels move in the same direction the machine moves in that direction
Turning is achieved by making the wheels oppose each other’s motion, thus generating a couple
In-place (zero turning radius) rotation is done by turning the drive wheels at the same rate in the opposite direction

DIODES
TRANSFORMER
POWER SUPPLY
Rectifier Circuit
IC 7805
USE
Rectifier Circuits are used to convert AC current to DC, as electronic components in Robots need DC current.
STEPS to CONVERT AC to DC
First the Transformer converts 220V AC to 12V AC
The Diode rectifies the current in a single direction
The Capacitor then normalizes the current
The little distortions are further rectified by the IC 7805
