Dragster Project: emphasis on controlDragster Project: emphasis on control

Control

• The dragster project focuses on control• Controlling electric motors is the basis

for many applications in industry Examples of applications include: standard power tools and machines – (most electric drills will reverse direction)automated machines, CNC machines, and robotic machines

• Control of motors is primary – desired motion is secondary

What is a dragster?

Shirley Muldowney NY won the Top Fuel Championship in 1977, 1980, and 1982 – ranked 5th in all time speed driver list.

Muldowney is Irish American – Don’t forget Tracey!

Dragster Theme

Expandable design - Body based on inter fitting aluminium channels. Two simple gearboxes and motors are used to drive large rear wheels. Each wheel may be controlled separately.
