Inexpensive Ultrahigh Vacuum Heatable/Coolable Xyz-Rotary Motion Sample Manipulator, Susan L. Peterson, Kirk H. Schulz, Carl A. Schulz, John M. Vohs Jan 1995

Inexpensive Ultrahigh Vacuum Heatable/Coolable Xyz-Rotary Motion Sample Manipulator, Susan L. Peterson, Kirk H. Schulz, Carl A. Schulz, John M. Vohs

Departmental Papers (CBE)

A simple design for a heatable, coolable, rotable sample manipulator, suitable for ultrahigh vacuum (UHV) applications, is described. Highlights of the design include using a combination power/thermocouple feedthrough for heating, cooling, and temperature measurement; and the use of primarily "off-the-shelf" components available from most UHV components vendors. The described manipulator is capable of sample cooling to ~100 K, sample heating to above 900 K, while maintaining 360o of rotary motion, ~1 in. of x and y motion, and 2 in. of z motion. The apparatus can be assembled for approximately $5500 (all new parts) and uses about 3 ...

This paper describes a simple visual servoing control algorithm capable of robustly positioning a three degree of freedom end effector based only on information from a stereo vision system. The proposed control algorithm does not require estimates of the gripper’s spatial position, a significant source of calibration sensitivity. The controller is completely immune to positional camera calibration errors, and we demonstrate robustness to orientation miscalibration through a series of simulations and experiments.

The Geometry Of A Robot Programming Language, Daniel E. Koditschek Jan 1995

The Geometry Of A Robot Programming Language, Daniel E. Koditschek

Departmental Papers (ESE)

This paper explores the problem of building robot navigation plans via scalar valued functions in the face of incomplete information about the configuration space such as might be available from onboard sensors. It seems as though syntactical aspects of navigation function construction may play an important role. This problem provides an important concrete instance of the need for intelligent control.
