automation of tractors due to their widespread use in different sectors e.g. agriculture, construction and industry have been seriously considered by researchers. in this study a tele-steering system for tractor was designed and constructed to controling and steering so the operator can control the tractor even far away from the stressful condition of tractor cab, . a cctv camera and an electri...

background isolated small gut mesentery injury after blunt abdominal trauma from the steering wheel in road traffic accidents is rare. these are always challenging to diagnose and pose a diagnostic dilemma. objectives to study the pattern of small gut mesenteric injury by steering wheel blunt abdominal trauma in road traffic accidents in patients who had laparotomy. patients and methods a 10-ye...

This paper presents a novel Current Steering Digital to Analog Converter architecture to reduce area as well as power dissipation. The current cells of conventional binary weighted architecture require larger size of transistors for MSBs. In this paper, same sized current cell transistors for MSBs as that of LSBs and a current mirror circuit is used between the load and MSBs to provide necessar...

A microactuator technology utilizing magnetic thin films and polysilicon flexures is applied to torsional micro-structures. These structures are constructed in a batch-fabrication process that combines electroplating with conventional IC-lithography, materials, and equipment. A microactuated mirror made from a 430x130x15 µm 3 nickel-iron plate attached to a pair of 400x2.2x2.2 µm 3 polysilicon ...

In this paper, kinetic and kinematic modeling of a 4 wheel steering vehicle is done and its movement is controlled in an optimal way using Linear Quadratic Regulator (LQR). The results are compared with the same control of two-wheel steering case and the advantages are analyzed. In 4 wheel steering vehicles which are nowadays more applicable the number of controlling actuators are more than the...

The outcomes achieved at the completion of a major industry-funded project undertaken by the CSIRO Mining Technology Group to advance the automation capability of continuous mining equipment in underground coal mining operations are reported. The details of a practical steering and guidance solution for autonomous Continuous Miner operation employing novel inertial navigation aiding techniques ...
