OVERVIEWAbout the ClientLimitationsSpecifications ImplementationAcknowledgements

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.

Control Panel The control panel will allow Shane to

start/stop the engine, control the lights, and let him know what gear he is in

TWO CONTROL MODES

Conventional Driving Mode

A conventional driving mode will 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

Joystick Mode The go kart will have the ability to be

controlled by a bidirectional joystick Forward: Throttle (+Y)

This engages a linear actuator that pulls a cable which in turn depresses the gas pedal

Backward: Brake (-Y) This engages a linear actuator that directly

depresses the brake pedal Left to Right: Steering (-X to +X)

This engages a DC motor which is connected to the steering column via a chain and sprocket system

Steering The steering is controlled with a Dayton Gear-motor that has

been geared to provide 75 in-pounds of torque Controls steering via a chain and sprocket system

Replaces the input to the steering column and controls the rack and pinion

The motor and steering column will have the same size sprocket as the motor, providing enough torque to turn the front wheels with a 1:1 ratio

Feedback to the microcontroller is provided by a linear sensor potentiometer

Throttle and Braking

Both the throttle and the braking are controlled by high speed linear actuators

Throttle- Linear actuator pulls on a pulley to accelerate.

Braking- Linear actuator presses against the brake.

SEAT Bucket Seat

Good lumbar support (padding) Taken from an electric wheel

chair Provides client with added

insurance of arm rests The seat is capable of folding

down on itself to provide access to the motor and electronics

5 point harness Will keep the client secure

when navigating difficult terrain

TWO MOST IMPORTANT

PARTS OF THE PROJECT

Microcontroller Controls the entire electronic system

(BRAIN) Arduino UNO PWM (PULSE WIDTH MODULATION) outputs

Firgelli Linear Actuator Control

Board LAC Firgueli Controls the speed, retraction limits, and

precision Gives feedback regarding the position of the

motor or actuator to the microcontroller
