Robotic car using 8951 Microcontroller

Robotic Car is a miniature prototype car powered by batteries whose various movements can be control either manually or automatically, or the combination of both.  Here the command is given through keyboard; it would have been better if we used IR remote control or something of that kind rather than using keyboard for commanding. However, by realizing the complexities we have made simple using keyboard.

Project Description:

Keyboard section:

There are six switches in this section. They are

  1. Turn left.
  2. Turn right.
  3. Stop.
  4. About turn.
  5. Park left.
  6. Park right.

Circuit diagram of keyboard is shown bellow.

Car section:

There are many sub sections in this section. They are

Motor:

We are using a 5V dc motor to drive the vehicle. The speed of the vehicle and its strength is controlled by the proper use of pulley. The rear wheel of the vehicle is connected to this motor through a pulley. This motor is meant for moving the vehicle both in forward and backward direction. Microcontroller (8051) controls the forward and backward movement of the vehicle in the following manner:

Here in the above circuit, T1, T2, T3, T4 are the NPN power transistor (2N3055). A0, A1, A2, A3 are the signals coming from the micro controller. With the specific combination of A0, A1, A2, A3 we can change the direction of rotation of motor as follows:

Case I: When   A0=high; A3=high; & A1=low; A2=low
The motor rotates in clockwise direction

Case II:
When   A0=low; A3=low; & A1=high; A2=high
The motor rotates in anti-clockwise direction

Case III:
When   A0=low; A3=low; A1=low; A2=low
The motor stops the rotation.

  13. HI ..I want to this project…..I have already done maual racing bot so I have half of the apparatus reqired..kindly send me details…including sircuit diagrams…thanks

  14. frnz,dont get into this project .i hv worked on it..the sensors shown here are quite different.designing transmitters for this series of sensors is difficult..these sensors dont work….contact me at survinderpal@yahoo.com

  15. Plz. send me all details and list of all components used in this robotic car and how we build this car …………..

  16. Plz. send me all details and list of all components used in this robotic car and how to build this car and also the complete program for this project…………..

  17. plz give me details on the prgram you used otherwise help me on this….and can you tell me the project you made was in running condition or not…..

  18. and one more thing there is not full circuit diagram given of this project so again plz help me on this too………

  19. sir can u plz send me all the details needed to do this project, specially the programming part…i’d be thankful.
    plz reply asap…

  20. plz send me all details of this project. i.e pcb, source code, ckt dia. component list etc..plz

  21. hey dude ur project is nice…. if u culd please send me the applications and the other details…it wuld be nice of u …nd if i want dis porjects please tell me the procedure how i’ll get it..
    thanx
