2. 1. On methods for assistive mobile robots

   Author : Sven Rönnbäck; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Electronics; Industriell elektronik;

   Abstract : This thesis makes a contribution to the field of autonomous vehicles, especially for use on assistive wheelchairs. Methods and technologies for topological signature maps, obstacle avoidance, door passing, localization, and navigation are presented. READ MORE

4. 2. On a robotic Matlab Java testbed for mobile robots

   Author : Sven Rönnbäck; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell elektronik; Industrial Electronics;

   Abstract : This thesis presents the MICA (Mobile Internet Connected Assistant) testbed and how it can be used to interface a mobile robotic system; in this case a modern wheelchair equipped with a CAN bus. In MICA we do research in embedded Internet systems, sensor technologies, navigation algorithms and in the knowledge about user. READ MORE

   Abstract : This thesis addresses a challenging problem: “how to let the visually impaired ‘see’ others emotions”. We, human beings, are heavily dependent on facial expressions to express ourselves. A smile shows that the person you are talking to is pleased, amused, relieved etc. READ MORE

6. 4. Screen Printed Large Area Sensors for Pressure Distribution Monitoring in Wheelchairs

   Author : Jawad Ahmad; Johan Sidén; Henrik Andersson; Xavier Crispin; Mittuniversitetet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : A sedentary lifestyle can induce health related problems including pressure ulcers. Pro­longed sitting inadequacies constitute a risk for pressure ulcer to many individuals, in particular people with disabilities and re­duced mobility. READ MORE

7. 5. Integrated In-Wheel Motors for Low Power Traction Application

   Author : Prakashraj Kasinathan; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electric golf cart; integral-slot; force density; flux-linkage; traction motors; forklift trucks; direct-drive; electric wheelchairs power wheelchairs; low speed machines; fractional-slot;

   Abstract : This thesis is primarily concerned with the practical limits, imposed by magnetic saturation and thermal considerations, of the force density in low-speed permanent-magnet electric machines. The practical force density values obtainable in integral- and fractional-slot machines are determined. READ MORE
