Dynamic knee alignment and collateral knee laxity and its variations in normal humans

open access: yesFrontiers in Surgery, 2015
Alignment of normal, arthritic and replaced human knees is a much debated subject as is the collateral ligamentous laxity. Traditional quantitative values have been challenged. Methods used to measure these are also not without flaws.

Exploring haptic interfacing with a mobile robot without visual feedback [PDF]

open access: yes, 2012
Search and rescue scenarios are often complicated by low or no visibility conditions. The lack of visual feedback hampers orientation and causes significant stress for human rescue workers. The Guardians project [1] pioneered a group of autonomous mobile
