Hello I'm a student of a Greek university and I want some help for my exercise...

First I have a robo-vehicle for tube cleaning

Now regarding the sensors and controllers I need you suggestion for

1. If one of three Ultrasonic Range Finders http://www.maxbotix.com/MB1000__LV-MaxSonar-EZ0.html detect an diameter smaller than 30cm a motor of 3.18 Nm, 12 V , 8 W should start.

2. Do i need a controller like http://www.vexrobotics.com/products/accessories/logic/276-2170.html
3. Do I also need a Motor Driver like http://www.robotshop.ca/cytron-24v-4a-brushless-dc-motor-driver.html

I really thank you in advance....
