Alternative confidence measure for local matching stereo algorithms

Author: Ndhlovu, T ; Nicolls, F Date: Nov 2009 The authors present a confidence measure applied to individual disparity estimates in local matching stereo correspondence algorithms. It aims at identifying textureless areas, where most local matching algorithms fail. The confidence measure ... Read more
Applications of autonomous robots in safety and security

Author: Sabatta, D Date: Oct 2012 In his talk, the author discusses the use of autonomous robots in safety and security-related applications, including safety inspections; search and rescue; soldier support; and surveillance. Read more
ARGUS: A pole climbing surveillance robot

Author: De Ronde, Wiilis ; Bosscha, Peter A ; Marais, Stephen T ; Pretorius, A Date: Nov 2023 Due to the high prevalence and unpredictability of violent protest action in South Africa, a need has arisen for rapidly deployable surveillance. This paper proposes an Automated Robotic Guardian for Urban Surveillance (ARGUS) platform, a ... Read more
Autonomous underwater vehicle for research and rescue operations

Author: Holtzhausen S ; Matsebe O ; Tlale NS Date: Nov 2008 Autonomous under water vehicles are ideal platforms for search and rescue operations. They can also be used for inspection of underwater terrains. These vehicles need to be autonomous and robust to cope with unpredictable current and high ... Read more
A brief overview of artificial intelligence in South Africa

Author: Ferrein, A ; Meyer, T Date: Oct 2013 One of the consequences of the growth in AI research in South Africa in recent years is the establishment of a number of research hubs involved in AI activities ranging from mobile robotics and computational intelligence to knowledge ... Read more
CHAMP: A bespoke integrated system for mobile manipulation

Author: Van Eden, Beatrice ; Rosman, Benjamin S ; Withey, Daniel J ; Ratshidaho, T ; Keaikitse, M ; Masha, D ; Kleinhans, A ; Shaik, A Date: Nov 2014 Mobile manipulation is a robotics paradigm with the potential to make major contributions to a number of important domain areas. Although some mobile manipulators are commercially available, bespoke systems can be assembled from existing and ... Read more
Clustered features for use in stereo vision SLAM

Author: Joubert, D Date: Jul 2010 SLAM, or simultaneous localization and mapping, is a key component in the development of truly independent robots. Vision-based SLAM utilising stereo vision is a promising approach to SLAM but it is computationally expensive and difficult to ... Read more
Design of an arbitrary path-following controller for a non-holonomic mobile platform

Author: Sabatta, DG Date: Nov 2009 Before a robot may be classed as an autonomous system, it must be able to move unaided in an environment. In a known environment or with pre-recorded trajectories, this reduces to the problem of path following. In order to follow an arbitrarily ... Read more
Development of a control model for a four wheel mecanum vehicle

Author: De Villiers, M ; Bright, G Date: Jul 2010 This paper presents the development of a control model for Mecanum wheels. Available control models used in robotics are based on a simplification which defines the contact point of the wheel on the ground as the point in the centre of the ... Read more
An embedded underground navigation system

Author: Hlophe, K Date: Nov 2011 Platform pose (localization and orientation) information is a key requirement for autonomous mobile systems. The severe natural conditions and complex terrain of underground mines diminish the capability of most pose estimation systems, ... Read more
Emergent situation awareness of drivable routes for autonomous robots using temporal probalistic reasoning

Author: Osunmakinde, IO ; Bagula, A Date: Nov 2009 In this paper, temporal probabilistic reasoning of the Emergent Situation Awareness (ESA) technology is proposed as a supportive strategy for autonomous navigation. The ability to reveal uncertainties over time is a drivable route awareness ... Read more
Evaluation of feature detection algorithms for structure from motion

Author: Govender, Natasha Date: Nov 2009 Structure from motion is a widely-used technique in computer vision to perform 3D reconstruction. The 3D structure is recovered by analysing the motion of an object, based on its features, over time. The typical steps involved in SFM are ... Read more
Fast and robust road segmentation and obstacle map generation for autonomous navigation

Author: Senekal, FP Date: Nov 2009 The ability to detect and navigate drivable road surfaces is an important research area in autonomous navigation for use in autonomous vehicles. In this paper, a probabilistic computer vision algorithm for segmentation of tarred road surfaces ... Read more
Grasping objects from a user’s hand using time-of-flight camera data

Author: Govender, Natasha ; Claassens, J Date: Nov 2010 For a robotic platform to be able to assist/interact in human environments, the platform must be able to perform some fundamental tasks. This includes interacting with humans by grasping or releasing objects as or when required by the human. ... Read more
Ground plane detection for autonomous robots in complex environments inclined with flexed far-field terrains

Author: Osunmakind, IO ; Ndhlovu, T Date: Nov 2009 In this paper, collective intelligence of the Emergent Situation Awareness (ESA) technology is proposed as a supportive strategy for autonomous robotic navigation. The ability to reveal uncertainties over time on flexed far-field is a ground ... Read more
Human detection for underground autonomous mine vehicles using thermal imaging

Author: Dickens, JS ; Green, JJ ; Van Wyk, MA Date: Jul 2011 Underground mine automation has the potential to increase safety, productivity and allow the mining of lower-grade resources. In a mining environment with both autonomous robots and humans, it is essential that the robots are able to detect ... Read more
Improved appearance-based matching in similar and dynamic environments using a vocabulary tree

Author: Sabatta, D ; Scaramuzza, D ; Siegwart, R Date: May 2010 In this paper the authors present a topological map building algorithm based on a Vocabulary Tree that is robust to features present in dynamic or similar environments. The algorithm recognises incorrect loop closures, not supported by the ... Read more
Integrating two spectral imaging systems in an automated mineralogy application

Author: Harris, D ; Viranna, N ; Hill, G ; Green, J Date: Nov 2009 A system for the automated analysis and sorting of mineral samples has been developed to assist in the concentration of heavy mineral samples in the diamond exploration process. These samples consist of irregularly shaped mineral grains ranging ... Read more
Kinematics design and human motion transfer for a humanoid service robot arm

Author: Dube, C ; Tapson, J Date: Nov 2009 This paper focuses firstly, on the kinematics structure required for a humanoid service robot arm and secondly, on transferring human motion obtained from visual motion capture to the humanoid arm. The kinematics structure of a ten Degree of ... Read more
Leisure robotics: an African child's gateway to programming
