##WELCOME EVERYBODY

![](./face_detect.jpg)

// To be replaced by live face detected image

!SLIDE x=-2000 y=0 rotate-y=50 scale=2

##*What is "Robot"* ?  

 <img src="troll_final.jpg" width="72%" />


!SLIDE x=0 y=-800 scale=1 z=500 rotate-x=-30

##Let's ***Google*** it  

 <img class="side" src="robot_def.jpg" width="85%"/>  
 

!SLIDE x=0 y=1500 rotate-x=45 scale=5

_**admin**_ : OK **Bot**, show us what can you do ...  

_**bot**_ : I can ...  

* Learn Skills ranging from electronics,  mechanics, controls, programming, etc ...  
*  Work in Industry assembly lines, like a robotic arm used for car-painting, parts assembling, etc...  

<img src="industry.jpg" width="50%" />

!SLIDE x=0 y=-1500 z=-1500 rotate-x=45 scale=5
##Contd...

* Function as a mobile robot such as terrestial, aerial, aquatic or hybrid vehicle
 be it manually controlled or autonomous.  
 
* Work in swarms to co-ordinate a task

##**So, what will you learn today ?**  

How about some robotics ?  
Well, we guess you already knew that :)

* First we'll talk about ***Manual Robotics***, the ones controlled by human (yup, that's you)  

* Then, we'll move on to autonomous bots, the ones which can perform simple tasks on their own. ( Remember Wall-E ? )  

* If time permits, we'll talk about robots with **"eyes"** (err.. cameras).

##Mechanical Construction  

- **Chassis**, i.e. the basic body structure (generally rectangular)
    - Preferred Material : Flex Board (25 cm x 25 cm)
    <img src="board.jpg" width="25%"/>
    
    - Others : Motor Clamps  
    <img src="clamps.jpg" />

## **Wheels**

- **Normal Wheels** , the ones you see in cars ... toy cars.  
    <img class="side" src="all_wheels.jpg" width="25%"/>
    <img class="side" src="wheel1.jpg" width="19%"/>
    
- **Castor Wheels** , a non-drivable wheel that is mounted at the bottom of a vehicle (or robot, in our case), that can move in any direction.  You can find them under the ( legs of ) movable tables.

##**DC Motors**  

- Runs on DC input.
- Types
    - **Geared Motor :**  
        - Pros:
            1. Used for bringing about a change in speed, by the use of gears.
            2. Also used to change axis and direction of motion  
        - Cons:
            1. No feedback mechanism.

##**DC Motors (contd.)**
  
- Types (contd.)
    - **Servo Motors**
        - Pros:
            - Used for high torque operations
        - Cons:
            - Costly

!SLIDE x=6200 y=4300 z=-1000 rotate-x=40 rotate-y=-30 scale=1

##Motion Direction Control  

- H-Bridge Circuit
    - Simple electrical circuit using which you can change the polarity at the load.  
    
<img src="h-br.gif" width="40%" />
    
!SLIDE x=8000 y=4300 z=-500 rotate-x=20 rotate-y=-45 scale=1

- Example:
    - DPDT Switch:  
    Switching device that uses H-Bridge principle to change the polarity of load and hence the motion of the motor whenever needed.

##Drives

- Types of drive we'll be using:
    - 2 wheel drive, 2 gearbox with castor wheel
    - 4 wheel drive, 4 gearbox
- Others
    - N Wheel Drive
    - Tank Wheel Drive

!SLIDE x=8000 y=500 z=1000 rotate-y=-15 scale=6 rotate-x=-15

##**2 wheel drive with castor wheel**

It has

- 2 active wheels with gearboxes
- 1 castor wheel for balance and free movement  

<img src="dr1.jpg" width="40%" />


!SLIDE x=13000 y=1500 z=1000 rotate-y=45 scale=10 rotate-x=45

##**4 wheel drive with 4 gearboxes**

It has 4 wheels connected with 4 gearboxes for fast and agile movement

##**Locomotion using Differential Drive system**

bot: I wanna move...  
admin: How?  
bot: Well now that you have asked so nicely...

- Differential Drive is one way to accomplish this  
<img src="drive.jpg" width="70%" />
- The simplest motions (shown above) occur when all of the wheels are moving  
- Different motions are also possible if we keep one/many wheels static

**SHOW TIME**  

We're pretty sure that you are bored to hell.  
So, here's a little treat for you.  

Sit back and enjoy :D

**Question time**  

Now, Throw something at us 

Just dont throw an error :P
