ROBOTIC vehicle design
« on: February 21, 2011, 11:24:57 PM »
i am planning to build a navigation robot wich follows a map transmitted to it through a computer via a bluetooth module.it aviods any obstacles in its way by the help of ir sensors.
the vehicle is a 3 wheelled base with the back wheels controlled by 2 dc motors of 12V,60RPM,70mA. The vehicle length is 20x15 cm.plz help me with other imp consideration that i should look into...  and how can i control the speed of the motor??

What motor driver are you going to use?
Which processor are you going to use?
What wheel speed senors (encoders) are you going to use?

The most common method to control DC motor speed is with PWM to the motor driver circuit (or chip). The PWM signal is generated by the processor (micro-controller) and also reads the wheel sensors to measure the wheel speed then adjusts the PWM duty to maintain the desired wheel speed.
