“…The power of the motor should be compatible to the power generated by the energy /the battery of the tractor. Optimal methods for headland turns include u-turning [7], keyhole turning/bulb turn/forward turning [8], fishtail turn/switch-back turning [9,10] and other methods modified from previous ones according to different shapes of headland [11][12][13]. In general, the changing of the gears is done manually by shifting the gear leaver to the desired gear according to the speed.…”

This paper is devoted to description of the method for operating the gear box and all the other Power Take Off (PTO) operations of tractor via remote control system by introducing certain computer/chip or a static/functional motor into the tractor's auxiliary power port.Standard Tractor comes with a manual gear box transmissions where gear changes require the driver to manually select the gears by operating a gear stick/leaver. Operation of the same from about a distance would reduce human consumption and efforts. Also the advantage of better mileage in case of manual transmission and to set the right gear according to the conditions of the field would be offered in this remote control operation.Also the remote controlled system will also reduce the physical and health issues faced by farmers while harvesting and get the benefit to operate all the functions sitting at a certain distance.

“…With the reconstruction of the chassis configuration, Schaeffler Mover can be applied to different types of vehicles. In addition to the vehicle companies, some universities also developed some 4WID-4WIS EV prototypes, including Jilin University [28,29], The Chinese University of Hong Kong (CUHK) [30][31][32], Massachusetts Institute of Technology (MIT) [33], Universiti Teknologi Malaysia (UTM) [34], Tongji University [35][36][37], Pusan National University [38], and Iowa State University [39]. Table 1 shows the performance analysis of the 4WID-4WIS EV prototypes.…”

In this paper, the related studies of chassis configurations and control systems for four-wheel independent drive/steering electric vehicles (4WID-4WIS EV) are reviewed and discussed. Firstly, some prototypes and integrated X-by-wire modules of 4WID-4WIS EV are introduced, and the chassis configuration of 4WID-4WIS EV is analyzed. Then, common control models of 4WID-4WIS EV, i.e., the dynamic model, kinematic model, and path tracking model, are summarized. Furthermore, the control frameworks, strategies, and algorithms of 4WID-4WIS EV are introduced and discussed, including the handling of stability control, rollover prevention control, path tracking control and active fault-tolerate control. Finally, with a view towards autonomous driving, some challenges, and perspectives for 4WID-4WIS EV are discussed.

“…Examination of a Jacobian matrix is the primary method used by researchers to quantify the kinematic performance of a robotic kinematic [11]. Conversely, dynamic performance can be defined as the wheel's perceived acceleration capability of the actuators or of the wheel itself [12]. In robotics literature, less attention has been paid to the dynamics analysis of mobile robots [13][14][15][16].…”

Wheeled mobile robot dynamics and suitable controller design are challenging but rewarding fields of study. By understanding the dynamics of wheeled mobile robots, it could be possible to design suitable hybrid control schemes for wheeled mobile robots. Since hybrid control schemes involve combining individual control methods to create a more effective overall control strategy. This can be done in a variety of ways, such as using fuzzy linear quadratic Gaussian control. We were therefore inspired to create dynamic models and their controller designs for the wheeled mobile robot by examining the dynamics of the wheeled mobile robot. The novelty of the current paper is to hybridize the different control schemes for wheeled mobile robots in order to get better performance. Entire systems models were simulated in a MATLAB/SIMULINK environment. The results obtained for the settling time response by FLQG were 87.1% over LQG; this study compared the effectiveness of current and previous FLQG controllers in external disturbances and found peak amplitude improvements of 71.25%. Therefore, the proposed controller is suitable for use with the wheeled mobile robot.
