Failure to grasp the rationale behind cleaning and shaping concepts can increase the occurrence of needless complications, such as ledges. A ledge is created when the working length can no longer be negotiated and the original pathway of the canal has been lost. Extension of the access cavity to provide unobstructed access to the root canals, precurving and not forcing instruments, using NiTi f...

In this paper, a greenhouse tomato picking robot chassis that meets the path cruising and setpoint positioning requirements of robots engaged in operations China is designed. Based on trellis-cultivation growing environment tomatoes, basic parameters operating space are analyzed to determine during operations. According these requirements, kinematic model with front-wheel steering rear-wheel dr...

The many degrees-of-freedom and distributed sensing capability of dextrous robot hands permits the use of control programs that rely on qualitative changes in sensor feedback rather than precise positioning and force information. One way of designing such a control program is to have the robot learn the qualitative control characteristics from examples. A convenient way of providing these examp...
