Caterpillar's New D8N Tractor with Differential Steering

SAE Technical Paper Series, 1987
<div class="htmlview paragraph">The D8N track type tractor at 213 kW (285 horsepower) was developed to provide a machine with large tractor features, yet carefully sized to be transported easily. In addition to incorporating the design features of Caterpillar's other large elevated sprocket tractors, the D8N has been equipped with a unique new ...

Reduction of Steering Effort in the Event of EPAS Failure using Differential Braking Assisted Steering

SAE International Journal of Transportation Safety, 2017
<div class="section abstract"><div class="htmlview paragraph">Electric Power Assisted Steering (EPAS) is widely adopted in modern vehicles to reduce steering effort. It is probable that some EPAS systems will experience a shutdown due to reliability issues stemming from electrical and/or electronic components.

Bio‐inspired Micropatterned Platform to Steer Stem Cell Differentiation

Small, 2011
1–4 ] Nevertheless, ineffi cient and uncontrolled differentiation along defi ned lineages as well as a lack of understanding of the microenvironmental cues that bring about homeostatic regulation severely restrict their therapeutic applications. To realize the full potential of stem cells, determinative strate-gies to control their differentiation are ...

Modeling and control design of differentially steered wheeled mobile robot

IECON 2017 - 43rd Annual Conference of the IEEE Industrial Electronics Society, 2017
In this paper, dynamic modeling and control design problems for planar motion of a differentially steered wheeled mobile robot (DSWMR) are analyzed. The dynamic model depends on the geometric configuration of the robot and helps in constructing robot trajectory. Two control design schemes are presented.

DEVELOPMENT OF A FORCED DIFFERENTIAL STEERING CONTROL SYSTEM

Automation Technology for Off-Road Equipment Proceedings of the 2004 Conference, 2013
Head feeding combine harvesters are requested high turning performance, because they must turn again and again during harvesting in slippage paddy of about 0.3ha in area. Thus they are equipped with rubber crawler and they cannot adapt Clutch and Brake system that is low turning performance.

Differential flatness of a front-steered vehicle with tire force control

2011 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2011
A trajectory tracking controller based on differential flatness is presented for a nonlinear bicycle model. This controller maps the bicycle dynamics into a point mass located at a center of oscillation with an additional degree of freedom of yaw dynamics.

Speed following control for differential steering of 4WID electric vehicle

IECON 2014 - 40th Annual Conference of the IEEE Industrial Electronics Society, 2014
This paper proposed a control strategy of differential steering specialized for four wheel independent driving (4WID) EVs. Different from traditional single torque-based control method, this strategy is designed to use the advantage of fast speed control of in-wheel motor.

Variable Structure Control of a Differentially Steered Wheeled Mobile Robot

Journal of Intelligent and Robotic Systems, 2003
This paper discusses dynamic modeling and robust control of a differentially steered mobile robot subject to wheel slip and external loads. Consideration of wheel slip and external loads is crucial for high load and/or high speed applications because they act as disturbances to the system. Furthermore, a tire model that adequately accounts for the tire/

Crawler Transaxle with Differential Lock and Variable Steering

SAE Technical Paper Series, 1982
<div class="htmlview paragraph">This transaxle is composed of two identical planetaries, a group of speed reducing gears that provide traction drive speed to each planetary through the sun pinions that are on a common shaft. Another group of steering, or differential lock gears provide power into the planetaries through the rotating ring gears ...
