Chlamydomonas shows both positive and negative phototaxis. It has a single eyespot near its equator, and as the cell rotates during the forward motion, the light signal received by the eyespot varies. We use a simple mechanical model of Chlamydomonas that couples the flagellar beat pattern to the light intensity at the eyespot to demonstrate a mechanism for phototactic steering that is consiste...

Production cars are designed to understeer and rarely do they oversteer. If a car could automatically compensate for an understeer/oversteer problem, the driver would enjoy nearly neutral steering under varying operating conditions. Four-wheel steering is a serious effort on the part of automotive design engineers to provide near-neutral steering. Also in situations like low speed cornering, ve...

differential steering of in-wheel electric vehicle provides the functions of both active steering and power assisted steering with the coupling control of force and displacement transfer characteristic of system. a collaborative optimization model of the differential power-assisted steering system of in-wheel electric vehicle is built, with steering economy as the main system optimization goal,...

Electric Power Steering (EPS) is a full electric system which reduces the amount of steering effort by directly applying the output from an electric motor to the steering system and has attracted much attention for their advantages. Controller design and software development of EPS is one of the key technologies that are critical to the system’s design. The constitutions and its operational mec...

The GOMOS Steering Front Assembly (SFA) is essentially a two axis pointing system. It comprises of a mirror (SMU), a Mechanism Drive Electronics unit (MDE) and a Steering Front Mechanism (SFM). Unlike many other pointing systems the SFA must maintain a line of sight stability of better than 3 microrads, while subjected to considerable microvibration disturbances from the host spacecraft. This p...

The hydraulic steering mechanism can lead the vehicle’s hydraulic system more complex and the tire wear heavier in the process of steering, which is detrimental to the steering control of the articulated motordriven vehicle. Thus the skid steering mode is implemented in the articulated motor-driven vehicle in this paper. This mode can simplify the vehicle without steering cylinder and it is mor...

Shuttle cars are an unusual class of vehicle in operation in underground coal mines. A directional control-response incompatibility has previously been described in some models which are steered using a steering wheel oriented perpendicular to the direction of travel. Other models are steered via a joystick. A virtual simulation of a joystick steered shuttle car was utilised to determine whethe...
