1. How TO Build A ROBOT Ur 1 st robot tutorial

2. MOTIVATION IS KEY TO SUCCESS  Why To build a robot?  You will learn skills ranging from electronics, mechanics, controls, programming  You should set your goals, otherwise you may quit in the middle

3. THE KISS APPROACH  THE 1 ST ROBOT IS ALWAYS THE HARDEST  SO KEEP IT SIMPLE  BEGINNER CAN SPEND AROUND 100- 200$ FOR HIS ROBOT

4. THE DESIGN  THE DUMB QUESTION IS, HOW DOES IT LOOK LIKE!  SO LETS START WITH A ROBOT HAVING 2 WHEELS  IT WILL DRIVE UNDER THE MOST BASIC ALGORITHM FOR A ROBOT- DIFFERENTIAL DRIVE

5. SELECTION OF WHEELS Big wheels will let your robot move faster than that of small wheels. Big wheels– less torque to carry payload, position control is harder, sensors cannot keep up Slow robots are boring, so go for 2-3 diameter wheel.

6. SELECTION OF MOTORS It involves calculation of weights, gearing ratio, velocity, acceleration, voltage,controls which becomes overwhelming for beginner. voltage – 5v-8v Torque – double that of what you need

7. SELECTION OF BATTERIES Rechargeable and having high energy capacity 3 common batteries  Alkaline battery  NIMH( Nickel Metal Hydride)  NICAD( Nickel cadmium )  2 NIMH – 6v

8. CIRCUIT DESIGN Microcontroller with a built in motor driver just literally plug in your battery, your motors/servos, and your sensor input/outputs, program it, and hurray your circuit is completed

9. TO MAKE IT AUTONOMOUS So lets learn about a basic sensor Use Photoresistor Place two sensors on either side and program it First design and then build a robot chassis

10. Tips Don't reinvent the wheels Join a local robotics club Participate in a robot competition As the size of robot increases, the difficulty also increases Most important - follow kiss approach
