Intercepting a Falling Object: Digital Video Robot

Internal models and prediction of visual gravitational motion

Baurès et al. [Baurès, R., Benguigui, N., Amorim, M.-A., & Siegler, I. A. (2007). Intercepting free falling objects: Better use Occam's razor than internalize Newton's law. Vision Research, 47, 2982-2991] rejected the hypothesis that free-falling objects are intercepted using a predictive model of gravity. They argued instead for "a continuous guide for action timing" based on visual informatio...

Title: Intercepting Free Falling Objects: Better Use Occam's Razor than Internalize Newton's Law

Proportional Navigation Guidance in Robot Trajectory Planning for Intercepting Moving Objects

This paper presents a novel approach to on-line, robotmotion planning for moving-object interception. A hybrid scheme, which combines a navigation-based technique with a conventional trajectory tracking method, is proposed for intercepting fast-maneuvering objects. The implementation of the proposed technique is discussed via a simulation example.

Intercepting free falling objects: Better use Occam’s razor than internalize Newton’s law

Several studies have recently provided empirical data supporting the view that gravity has been embodied in a quantitative internal model of gravity thereby permitting access to exact time-to-contact (TTC) when intercepting a free falling object. In this review, we discuss theoretical and methodological concerns with the experiments that supposedly support the assumption of a predictive and acc...

Minimizing Amplitude of Oscillation of a Suspended Object during Transport by a Robot

– One of the important applications of robots is in material handling and transport of various shaped objects. In cases where an object cannot be directly grasped by the robot gripper, and must be carried by a hook, it may be subject to undesirable swings during transport. This paper presents an analytical method for minimizing the oscillation of a suspended object during transport. This method...
