  • BS-SLAM: shaping the world 
    Pedraza Luis; Dissanayake Gamini; Valls Miro Jaime; Rodriguez-Losada Diego; Matia Fernando (MIT Press, 2007)
    This paper presents BS-SLAM, a simultaneous localization and mapping algorithm for use in unstructured environments that is effective regardless of whether features correspond to simple geometric primitives such as lines ...
  • Dynamic Bayesian Networks for Learning Interactions between Assistive Robotic Walker and Human Users 
    Patel Miteshkumar; Valls Miro Jaime; Dissanayake Gamini (Springer-Verlag Berlin Heidelberg, 2010)
    Detection of individuals intentions and actions from a stream of human behaviour is an open problem. Yet for robotic agents to be truly perceived as human-friendly entities they need to respond naturally to the physical ...
  • An efficient strategy for robot navigation in cluttered environments in the presence of dynamic obstacles 
    Taha Tarek; Wang Dalong; Valls Miro Jaime; Dissanayake Gamini; Liu Dikai (University of Technology, Sydney, 2007)
    A novel method which combines an optimised global path planner with real-time sensor-based collision avoidance capabilities in order to avoid moving obstacles (e.g. people) in a complex environment is presented. The ...
  • Information efficient 3D visual SLAM in unstructured domains 
    Valls Miro Jaime; Zhou Weizhen; Dissanayake Gamini (The Institute of Electrical and Electronic Engineers Inc (IEEE), 2007)
    This paper presents a strategy for increasing the efficiency of simultaneous localisation and mapping (SLAM) in unknown and unstructured environments using a vision-based sensory package. Traditional feature-based SLAM, ...
  • A kyno-dynamic metric to plan stable paths over uneven terrain 
    Valls Miro Jaime; Dumonteil Gaultier; Beck Christoph; Dissanayake Gamini (IEEE, 2010)
    A generic methodology to plan increasingly stable paths for mobile platforms travelling over uneven terrain is proposed in this paper. This is accomplished by extending the Fast Marching level-set method of propagating ...
  • A multi-stage shared control method for an intelligent mobility assistant 
    Arblaster Jaimal; Liu Dikai; Mclachlan Skye; Valls Miro Jaime; Chenoweth Lynnette (The Institute of Electrical and Electronic Engineers Inc (IEEE), 2005)
    This paper presents a multi-stage shared control method (MSSC) which can be used to control the movement of a robotic mobility assistant designed to facilitate safe mobilization for people with unstable gait. The ...
  • Robotics for urban search and rescue 
    Paxman Jon; Valls Miro Jaime; Dissanayake Gamini; Thane Oliver; Thi Hue Tuan (The Institute of Electrical and Electronic Engineers Inc (IEEE), 2006)
    This paper describes a team of robots that are designed for urban search and rescue applications. The team CASualty consists of four tele-operated robots and one autonomous robot. A brief description of the capabilities ...
  • Sampling based time efficient path planning algorithm for mobile platforms 
    Taha Tarek; Valls Miro Jaime; Dissanayake Gamini (IET (Institution of Engineering and Technology), 2006)
    In this paper we present a time efficient one step path planning algorithm for navigating a large robotic platform in indoor environments. The proposed strategy, based on the generation of a novel search space [1], ...
  • Semi-Autonomous Competency Assessment of Powered Mobility Device Users 
    Valls Miro Jaime; Black Ross; De Bruijn Freek; Dissanayake Gamini (IEEE, 2011)
    This paper describes a stand-alone sensor package and algorithms for aiding the assessment by an occupational therapist whether a person has the capacity to safely and effectively operate a powered mobility device such as ...
  • Vision-based SLAM using natural features in indoor environments 
    Dissanayake Gamini; Valls Miro Jaime; Zhou Weizhen (The Institute of Electrical and Electronic Engineers Inc (IEEE), 2005)
    This paper presents a practical approach to solve the simultaneous localization and mapping (SLAM) problem for autonomous mobile platforms by using natural visual landmarks obtained from an stereoscopic camera. It is ...
