This paper describes an integrated autonomous driving (AD) control system for vehicle with four independent in-wheel motors (IWMs). The consists of two parts: the AD controller and chassis controller. These elements are functionally to improve stability path tracking performance. is assumed employ IWM independently at each wheel. implements longitudinal/lateral using proportional-integral(PI) a...

using instrumented tractors to monitor and record spatial variations in performance parameters of tractor and implements during field operations, could improve productivity and the tractor efficiency. in the context of precision farming, this information can be used to map spatial variability of the parameters and to find the relations with changes in soil attributes (texture, moisture contents...

The combination of a disulfonated-dibenzo-24crown-8 ether wheel and a dicationic 1,2-bis(pyridinium)ethane axle yields a neutral [2]pseudorotaxane which in combination with neutral metallic units such as a Cu(II)benzoate paddlewheel or Cu(I)Br unit yields one-dimensional coordination polymers (linear and bent) which are the first examples of charge neutral, metal-organic rotaxane frameworks.

The one-pot syntheses of a series of dimeric and trimeric selenotungstates based on the [Se2W12O46](12-) unit are presented alongside the structure of the tetrameric [Se8W48O176](32-) wheel. Mass spectrometry has probed the stability of these clusters whilst their electronic structure has been contrasted to their known phosphotungstate analogues.

The Mecanum wheel was designed in Sweden in 1975. Using four of these wheels provides omni-directional movement for a vehicle without needing a conventional steering system (Muir & Neumann, 1990; Dickerson & Lapin, 1991; Braunl, 1999; Navy, USA, 2002 and Lunze & Schmid, 2002). The wheel itself consists of a hub carrying a number of free moving rollers angled at 45° about the hub's circumference...

Minimally invasive procedures such as biopsy or thermal tumor ablations share a similar planning scenario: a linear path for a needle shaped instrument has to be found such that the needle tip can reach a defined target such as a tumor. The path should be chosen according to several criteria, which influence safety, practicability and, in the case of ablation techniques, the ablation success of...

In this paper an evolutionary algorithm is developed to learn a fuzzy knowledge base for the control of a soccer playing micro-robot from any configuration belonging to a grid of initial configurations to hit the ball along the ball to goal line of sight. The knowledge base uses relative co-ordinate system including left and right wheel velocities of the robot. Final path positions allow forwar...
