Robotic car using 8951 Microcontroller
by Ranjith | November 19th, 2008.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
- Turn left.
- Turn right.
- Stop.
- About turn.
- Park left.
- 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:
Circuit diagram of Motor connection
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.
