We describe a behavior-based control system that enables a non-holonomic robot to push an object from an arbitrary starting position to a goal location through an obstacle eld. The approach avoids the need for maintaining an internal model of the target and obstacles and the potentially high computational overhead associated with traditional path planning approaches for non-holonomic robots. Th...

INTRODUCTION Handball is a high-intensity sport with frequent physical contact between players. The physical demands are characterised by intermittent sprinting. Match play involves high-speed running forwards, backwards as well as sideways, plant and cutting movements, jumps, landings, turns, and repeated acceleration and deceleration movements. Most of the play in handball involves balancing ...

Following obstacle free paths towards the ball and avoiding opponents while dribbling are key skills to win soccer games. These tasks are challenging as the robot’s environment in soccer games is highly dynamic. Thus, exact plans will likely become invalid in the future and continuous replanning is necessary. The robots of the RoboCup Standard Platform League are equipped with limited computati...

A middle aged labourer was admitted into hospital for prolapse of the rectum about 4 inches in length, with discharge of mucus, tenesmus and incontinence of urine for the past li years. His main complaint was the continuous dribbling of urine. A tentative diagnosis of chronic bacillary dysentery, which had caused the rectal prolapse, and a reflex irritation of the bladder causing incontinence w...

Anterior urethral valve is an uncommon abnormality whose etiology is uncertain, unlike in the case of posterior urethral valve. Glanular anterior urethral valve is even rarer. We present an unusual case of anterior urethral valve, which presented with acute urinary retention and was successfully managed with excision and glans reconstruction. A history of poor stream and dribbling, recurrent ur...

persistent patent urachus with other accompanying anomalies like urethral obstruction and uroperitoniumquickly deteriorates animal conditions which necessitate prompt surgical intervention and animal salvage. a10-day-old calf was referred to clinic with mildly distended abdomen, history of umbilical dribbling and nosigns of normal urination since birth. on clinical laboratory results and ancill...
