Project Objectives To create a kit-

ready modification to the Gator gas and brake controls in order to facilitate accessibility by those unable to use the foot pedals

Current Status Group has decided upon lever design (i.e., no

electronics, hydraulics, etc.) Challenges remain:

• Managing 80lb required to depress brake• Restrained by limited travel in Gator and

position of existing 4WD and parking brake levers

• Making kit removable—ideally no pulleys• Avoid blocking brake and gas pedals if possible

Previously Chosen Design

Class Critique of Design Pivot bar will not be ideal for sensitive control

needed for the accelerator. Same lever for brake and gas effected by not

connecting brake to the lever; this allows disengagement during activation of the accelerator.

Hand lever system could travel over dash console to reach levers beneath hood.

Class agrees that the throttle lever design is the most feasible design.

Design Modifications-Unattached Brake Lever

Considering a mechanism in which the brake lever is not attached but simply applies force to a connecting member.

Design Modifications- Updated chosen design

Action Items- coming week Consider ways to eliminate pulley and avoid

obstructing pedals if possible while retaining a lever design.

Decide upon prototype design and plan materials needed

Begin building first prototype to test and tweak concept

Sketch assembly drawings in Pro-E
