TL;DR: A portable mechanical design that can be fabricated and fit into existing vehicles and can be used as a platform to develop an autonomous car is proposed.
Abstract: Drastic changes in the robotics and intelligent controls brought a radical change in Automotive engineering sector that leads to the driverless vehicles in this new era. For these vehicles to safely run in today's traffic and in harsh environments, a number of problems in vision, navigation, and control have to be solved. Driverless cars use sensors to detect the environment, computers to process the data and actuators for mechanical systems. To adopt the self driving car technology to current academic and research, we need a cost efficient and affordable mechanisms. In this scenario we need a system that can incorporate existing vehicles and convert that driverless cars which will reach to academicians and research fields. Considering the possibilities and implementation of driverless vehicles in Indian scenario we need an agile mechanical design to be included on existing vehicles. This paper proposes a portable mechanical design that can be fabricated and fit into existing vehicles and can be used as a platform to develop an autonomous car. Conventional cars can be altered to be a driverless car by using different actuators. Popularly motors are used as actuators in the automation of the vehicle. A pneumatic system is designed to automate the intended platform apart from the motors. The mechanical structure is an essential part of an autonomous car and is to be altered and designed in such a way that it is dynamically unwavering. Further improvements will make the system capable of being commercially produced.

TL;DR: Performance comparison is done between manual and pneumatic shifting mechanism based on basic criteria’s like shifting time, driver safety, weight of the system and complexity of the systems.
Abstract: In this paper Design scheme of Pneumatic gear shifting mechanism for a shifter kart has been introduced. Shifter karts are included in open wheel, four wheeled racing categories with usually no suspension. Performance comparison is done between manual and pneumatic shifting mechanism based on basic criteria’s like shifting time, driver safety, weight of the system and complexity of the system. Results depict pneumatic shifting mechanism counts more pros over traditional shifting mechanism in various aspects of performance. Keywords— Shifter kart; pneumatic; compressor; DCV; reservior;

TL;DR: In this article, a semi automatic gear shifting mechanism for a Go-Kart has been designed to resolve the gear shifting problem, eliminate the fully mechanical gear shift and reduce the effort of the driver.
Abstract: Design and fabrication of a semi automatic gear shifting mechanism for a Go Kart a racing car. This gear shifting mechanism had been design to resolve –gear shifting problem, eliminate fully mechanical gear shift ,to have a better control over the steering, to reduce the effort of the driver and to reduce the gear shifting timing which is most important deciding factor in race like scenario where few milliseconds make you a winner or a loser. The idea of pneumatic shifter rose from discussion on alternate methods of the shifting mechanism. Performing the basic analysis, the design was made on the available data and the final design was implemented. Keywords—Shifter,Pneumatic,Go-Kart, Automation, Design.

TL;DR: In this paper, a gear shifting mechanism was designed and applied on a featured bike to make the gear transmission process faster and lessdestructible for the driver using internet, which makes vehicle driving easier and to achieve efficient driving.
Abstract: The present automatic transmission is fully mechanically controlled and costs very high. In this study, a gear shifting mechanism was designed and applied on a featured bike to make the gear transmission process faster and less destructible for the driver using internet. But the gear transmission mechanism designed makes driving easier and to achieve efficient driving. This new device must be reliable, has small dimensions, economical and low maintenance cost. This project aims to improve the gear shifting process with a suitable control mechanism to implement in clutch featured bikes. According to the suggested gear shifting method, which selects the transmission gear as per the speed of the vehicle without direct human interference. A pneumatic shifter is a mechanical device that uses compressed air to shift a gear controls the engaging and disengaging of gears using internet of things principle to control automatically. There is no lag time in a gear shifting operation and taking hold in the rest of the vehicles.

TL;DR: In this paper, a gear shifting mechanism was designed and applied to make the shifting process faster and less destructible for the driver, which can select the transmission gear ratio without moving his hands from the steering wheel.
Abstract: In this study, a gear shifting mechanism was designed and applied to make the shifting process faster and less destructible for the driver. The new device must be reliable, has a small dimensions, low construction and maintenance cost. This paper aims to improve gear shifting process using devices as: a manual four speed gear box, four pneumatic double acting cylinders, four pneumatic two position five ways directional control valves, Programmable Logic Controller (PLC) LOGO unit, an electrical motor, an electrical clutch, a belt, two pulleys, limit switches, push buttons, bulbs, a table (holder) and power supply. According to suggested gear_ shifting method the driver can select the transmission gear ratio without moving his hands from the steering wheel by putting the gear shifting push buttons on the steering wheel. Using this method leaves to the driver the excitement of choosing the shifting moment.
