In vitreoretinal surgery – surgery on the back of the eye – surgeons benefit from robotic assistance. An important step during robotic assistance is tracking the back of the eye. However, during surgery, an eye can move in its socket and current visualization techniques cannot view the entire retina in one shot. Hence, tracking the position and the shape of(More)
In this paper we discuss improvements in mechanical, electrical and software design of our middle-size league robots. Regarding hardware and control recent progress includes a prototype design of a ball clamping system, and first steps towards improved passing accuracy via velocity feedback control on the shooting lever. In terms of intelligent gameplay we(More)
Vitreoretinal eye surgery requires ultimate surgeon's precision and skills. Significant variation exists in the approaches between different surgeons. Procedures are often indicated as difficult to perform. The surgeon's personal skill level is considered critical, including hand motion stability and left/right hand dexterity. Precision of instrument(More)
In this paper we discuss the progress in mechanical, electrical and software design of our middle-size league robots over the past year. Recent process in software includes intercepting a lob pass and improvement of 3D ball detection by combining omnivision output of different robots. For better localization the distance mapping and mapping center are(More)
