In this paper, two approaches to generating such trajectories: straight lines in joint space and straight lines in Cartesian space have been discussed. This is one of the most common requirements in robotics for moving the end-effector smoothly from initial location to goal location. These are known respectively as joint space and Cartesian space tracking. Two user defined algorithms are develo...

AIM The mutual position of the distal fibular physis compared to the tibiotalar joint space in the immature skeleton was investigated in X-ray studies. The clinical relevance of the recorded mutual position was evaluated for paediatric skeletal traumatology. MATERIALS AND METHODS 140 radiographs of immature ankle joints without skeletal injury were reviewed and the mutual position of the dist...

James D. English and Anthony A. Maciejewski Purdue University 1285 Electrical Engineering Building West Lafayette, Indiana 47907-1285 Abstract Robotic joint failures are directly characterized and measured in joint space. A locking failure, for example, is one for which a joint cannot move, and it gives an error equal to the desired value minus the locked value. This article extends the joint-s...

Arthroscopic shoulder surgery can be performed in both the beach chair and lateral decubitus positions. The lateral decubitus position allows for excellent exposure to all aspects of the glenohumeral joint and is therefore frequently employed in procedures such as stabilization, in which extensive visualization of the inferior and posterior aspects of the joint is required. Improved visualizati...
