Bloodhoud Steering Wheel Contest Submission by Ian Sayers

This version of the Bloodhoud Steering Wheel is a yoke-style cutaway wheel with ergonomic grips and a twin-lever compensating throttle control sytem. The 3 required buttons are ergonomically integrated into the grips and are activated with the thumbs. An extra feature on this design is a kill switch attached to the right throttle lever. If the driver blacks out, the wrist band pulls the kill switch as the driver's hand falls to his/her lap. The lower section of the frame is rounded downward and has no sharp angles that could potentially catch the driver's glove and prevent the kill switch from detaching. The Rev B model contains a number of ergonomic and cosmetic revisions and omits the kill switch. The ergonomics were developed using a 3d printer to test for fit. I chose a dual lever system because it is less sensitive to turbulence and provides more stability by allowing control with both hands. The levers are connected to each other by a cable, which winds around an internal central pulley, so when one lever is pulled in, the other compensates by extending. There is no spring load, but they have resistance and stay where positioned, somewhat like the dual-lever steering system of a Bobcat.
