The representation and manipulation of sound within multimedia systems is an important and currently under-researched area. The paper gives an overview of the authors’ work on the direct manipulation of audio information, and describes a solution based upon the navigation of fourdimensional scaled timbre spaces. Three hardware input devices were experimentally evaluated for use in a timbre spac...

Low-cost robots are characterized by low computational resources and limited energy supply. Path planning algorithms aim to find the optimal path between two points so the robot consumes as little energy as possible. However, these algorithms were not developed considering computational limitations (i.e., processing and memory capacity). This paper presents the HCTNav path-planning algorithm (H...

In this study, we design autonomous navigation, guidance and control system for small four-wheel ground vehicle. Small and low-accuracy sensors (low-cost GPS, low-accuracy accelerometers) are only used for navigation and control of the UGV. Firstly, INS/GPS composite navigation system is designed to obtain high-accuracy position and velocity of the vehicle by using low-accuracy sensors. Secondl...

In environments where GNSS is unavailable or not useful for positioning, the use of low cost MEMS-based inertial sensors has paved a way to a more cost effective solution. Of particular interest is a foot mounted pedestrian navigation system, where zero velocity updates (ZUPT) are used with the standard strapdown navigation algorithm in a Kalman filter to restrict the error growth of the low co...

Autonomous mobile entity navigation through dynamic and unknown environments is an essential part of many mission critical applications like search and rescue and fire fighting. The dynamism of the environment makes it particularly difficult to achieve navigation using just on-board sensors and existing navigation methods. This motivates the integration of wireless sensor networks with navigati...

This paper provides algorithms to fuse relative and absolute microelectromechanical systems (MEMS) navigation sensors, suitable for micro planetary rovers, to provide a more accurate estimation of navigation information, specifically, attitude and position. Planetary rovers have extremely slow speed (~1 cm/s) and lack conventional navigation sensors/systems, hence the general methods of terrest...
