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.

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
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
