TLDR
This self-propelled robotic endoscope has potential as an alternative to current fibre optic colonoscopy examination methods, especially with the addition of new sensors under development.Abstract:
Purpose
Fibre optic colonoscopy is usually performed with manual introduction and advancement of the endoscope, but there is potential for a robot capable of locomoting autonomously from the rectum to the caecum. A prototype robot was designed and tested.read more

Regret Bounds for the Adaptive Control of Linear Quadratic Systems
TL;DR: The construction of the condence set is based on the recent results from online least-squares estimation and leads to improved worst-case regret bound for the proposed algorithm, and is the the rst time that a regret bound is derived for the LQ control problem.

Wireless capsule endoscopy
TL;DR: A new type of endoscopy, which for the first time allows painless endoscopic imaging of the whole of the small bowel, is developed and successfully tested in humans.
Journal ArticleDOI
Wireless capsule endoscopy.
TL;DR: There is a clinical need for better methods to examine the small bowel especially in patients with recurrent gastrointestinal bleeding from this site, and small bowel endoscopy is currently especially limited by problems of discomfort and failure to advance enteroscopes far into theSmall bowel.
