My Lawn Mover Project

[JangKang]

Before that, our Project is Grass Cutter (Lawn Mover) which its control by RF(remote control) and use electric power. because our scope is Green Technologies.

My Motor for move my project tyre is :
12V DC motor, speed: 10000, speed with Load: 2500rpm
power: 120W-600watt, peak standstill torque = 4.5Nm.

here, i was think wanna use PIC16F877A and L293D and relay to control the motor which its will be trigger by RF (radio frequency).
any one can comment, can advise me, suggest me the programming coding, the circuit diagram that suitable.....

my basic diagram circuit:
RF(Tx)>>>>(Rx)>>>>PIC16F877A>>>>>L293D>>>>>>Relay>>>>DC Motor.

other circuit also is my project require is, motor for cutter pillar.....
