2. What is a Robot ? 3. Types of Robots Manual Robots Autonomous Robots 4. BASIC PARTS OF A ROBOT CHASSIS WHEELS BATTERY MOTORS DPDT 5. CHASSIS 6. CHASSIS MEANS??? The basic framework of a robot where motor, wheels , battery etc are mounted. Chassis can be of any shape and size depending on the use and application, different types of chassis are as follows..... 7. ROUND OR CIRCULAR CHASSIS 8. SQUARE OR RECTANGULAR CHASSIS 9. Why Chassis is used?? To mount all the parts and accessories to a robot. To give stability and basic shape to a robot. 10. Material used for making chassis Wood MS Aluminium Plastic CI composites 11. GROUND CLEARANCE 12. BASIC PARTS OF A ROBOT CHASSIS WHEELS BATTERY MOTORS DPDT 13. WHEELS 14. simple wheels 15. Omni wheel 16. Mecanum wheel 17. Factors for selection of wheels Diameter Grip Ground clearance Material of wheel 18. DIAMETER Wheel should be selected keeping in mind- Speed diameter Force 1/diameter 19. GRIP- Provided to give enough friction. Ground Clearance Material-chosen according to strength 20. CASTOR WHEEL 21. BASIC PARTS OF A ROBOT CHASSIS WHEELS BATTERY MOTORS DPDT 22. BATTERY 23. LEAD ACID BATTERY 24. LI-PLOYMER OR LI-PO BATTERY 25. LI-ION BATTERY 26. Different Parameters for the selection of Battery Voltage Rating Ampere-Hour Rating Max. Current Rating Chargeable-Non Chargeable 27. SOME COMMON MISCONCEPTIONS Battery can not draw current more than its Ampere-Hour Rating. Discharging of battery means decreasing of Battery Voltage. Charging a Battery after fully discharging it is beneficial 28. DRIVING MECHANISM 29. BASIC PARTS OF A ROBOT CHASSIS WHEELS BATTERY MOTORS DPDT 30. MOTORS 31. Selection of motors On the basis of voltage limit. On the basis of speed-torque relation. POWER= TORQUE x RPM For constant power Speed 1/Torque 32. Vega motor 33. Johnson Motor 34. BLDC 35. MechTex 36. Stepper Motor 37. Servo motor 38. MOTOR MOUNTINGS AND FITTINGS 39. NUT , BOLTS 40. BASIC PARTS OF A ROBOT CHASSIS WHEELS MOTORS BATTERY DPDT 41. DIFFERENT SWITCHES 42. DPDT SWITCHES 43. H-BRIDGE 44. How to make an H-Bridge with a DPDT switch..?? 45. DPDT connections 46. CONECTION OF A DPDT SWITCH TO MAKE A H-BRIDGE 47. Plastic switches should be avoided in some specific purpose where more heat is produced in circuit and wires as they melt down 48. WIRES- low resistance wires should be chosen keeping in mind the heating effect produced due to the wire in the circuit 49. Bot with chain drive 50. BOT WITH BELT DRIVE 51. DOUBTS????????? 52.
