OVERVIEW•About the Client•Limitations•Specifications•Implementation•Budget

Shane Davis• Age: 20 years old• Weight: 120 pounds• Height: 5’ 3”• Disability:

• Cerebral Palsy• Spastic Quadriplegia

Limitations• Cerebral Palsy and Spastic Quadriplegia

• Spastic quadriplegia is a form of cerebral palsy in which all four limbs are affected.

• The condition is referred to as spastic rather than paralysis because the patient has some movement in all of his limbs.

• Shane has very limited hip movement and strength, which when combined with severe quadriplegia leaves him confined to a wheel chair.

Mechanical Aspect of Kart• 90cc 4-stroke gasoline motor

with electric start• Steel frame

• Dimensions (L*W*H): 66”x42”x40”

• Hydraulic disc brakes• 220 pound weight capacity• Automatic transmission with

reverse• Full suspension with 3.3” of

travel• All terrain tires

Steering• The steering is controlled with a Dayton

Gearmotor• The gearmotor increases the torque at the

drive shaft to 75 in-lb at 90 RPM• Replaces the input to the steering column and

controls the rack and pinion• Feedback to the microcontroller is provided

by a linear potentiometer

Conventional Driving Mode

• A conventional driving mode will also be available for Shane• The brake and gas pedal are both

depressed manually• The steering wheel will input

information to a rotational potentiometer• This information will be relayed through a

microcontroller which will engage the electric motor and turn the front wheels

Throttle and Braking• Both the throttle and the braking are

controlled by high speed linear actuators• When engaged the actuators will depress

their assigned pedal by pushing on a cup that is attached to an extension of the pedals

SEAT• Bucket Seat

• Good lumbar support (padding)

• Leg Extensions • A trough to hold

his legs in place

• Leg Support• Extra cushioning
