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

3. Shane Davis • Age: 20 years old • Weight: 120 pounds • Height: 5’ 3” • Disability: • Cerebral Palsy • Spastic Quadriplegia

4. 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.

5. Product Specifications Major Components • 90cc electric start Gasoline engine • Full support seat with armrest control panel • Cushioned seat with 5-point harness • Fully automated hydraulic braking • Fully automated electric steering • Fully automated throttle • Automatic transmission with reverse • 4-wheel independent suspension Major Modifications • Joystick controller • Multidirectional for throttle, braking, and steering control • Ability to use a conventional driving setup • Low resistance steering wheel with electric steering • Remote starter with kill switch • Onboard kill switch • Rugged electronics for off-road use

6. 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

7. 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

8. 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

9. 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

10. SEAT • Bucket Seat • Good lumbar support (padding) • Leg Extensions • A trough to hold his legs in place • Leg Support • Extra cushioning • 5 point harness

11. Joystick Controls • The go kart will have the ability to be controlled by a multidirectional joystick • Forward: Throttle • Backward: Brake • Side to side: Steering

12. Budget

13. Future Work Brahmatej Meka • Seat modifications: seating, harness, and arm rests • Microcontroller with Miratron • Solid Works Design Raymond Songer • Steering: motor mount, potentiometers, chain and sprocket • Microcontroller Jeff Marcelus • Actuators, pedal extensions and Solid Works Design
