Comparing the Performance Evaluation of an Adaptive Left Throttling Pedal for V-Boot Wagon 230 for Right Leg Paraplegic Patient with Existing Model Using R? Console

This work is problem- solving oriented. A Design and Fabrication of an Adaptive Left Throttling Pedal for V-Boot Wagon 230 was done for right leg Paraplegic Patient who has a problem with his right leg and still desire to drive his car with ease. The uniqueness of this work is that this adaptation could be used for any modern car. Although there were various car adaptations in existence mainly customized for paraplegia that have been developed by different International Automobile industries. Nigeria is yet to have one. The clauses behind the design of this work are the difficulties to access left adaptive throttling accessories for V-Boot Wagon 230 for Right Leg Paraplegic patient and possibility of driving the car upon reverting the car to its existing state. On the course of achieving this research work, the following factors were considered; Anthropometric data of the client, Physical dimensions of available spaces for left throttle, design analysis which includes adaptive link mechanism, material selection, strength, and forces were determined, fabrication, machining of parts and assembling, Installation of the product, equipment maintenance and Performance evaluation. Ordinarily the engines speed runs 2000rpm at an idle position of the existing pedal compared to what has been adapted which runs at 1500rpm. This low speed indicates improved efficiency and minimizes fuel consumption. Also when the two pedals were activated and pressed through an arc length of 45mm, both engine speeds read 6000rpm. Although there were little deviations in the curves at displacement position 20mm and 30mm of which R Console was used to test the significance of this deviation on the performance of the adapted throttling pedal. Welch Two Sample t-test was computed in Rconsole module to investigate the results obtained upon using both adapted pedal and the existing pedal under the same displacement values. It was observed that the analysis yielded p-value of 0.4557 which is less than 0.95 confidence level chosen for t-test computation with sample means estimates of 3900rpm and 3750rpm. This result indicates that there is no significance difference in the performance evaluation of the two systems
