A low cost tellurometer
This thesis describes the development of a low-cost microwave electronic distance measurement instrument using the Tellurometer phase-measurement principle. In a simplified form the instrument can be configured as a full-duplex 9 600 Baud datalink. The Tellurometer was invented in 1957 by the late …

Explorations in low-cost compliant robotics
… presents the findings of exploratory research in low-cost compliant robotics. The most heavily leveraged trade-off is that of mechanical precision for computational power, with the hope that the price of future computation will continue to fall exponentially while the expected price of precision …

Design of a low cost hydrostatic bearing
This thesis presents the design and manufacturing method for a new surface self compensating hydrostatic bearing. A lumped resistance model was used to analyze the performance of the bearing and provide guidance on laying out the bearing features. One arrangement of bearing features was cut into a …
