A New Approach to Visual-based Sensory System for Navigation into Orange Groves

ABSTRACT

One of the most important parts of an autonomous robot is to establish the path by which it should navigate in order to successfully achieve its goals. In the case of agricultural robotics, a procedure that determines this desired path can be useful. In this paper, Continue reading

Random Finite Set based Bayesian Filtering with OpenCL in a Heterogeneous Platform

ABSTRACT

While most filtering approaches based on random finite sets have focused on improving performance, in this paper, we argue that computation times are very important in order to enable real-time applications such as pedestrian detection. Towards this goal, Continue reading

Intelligent Robot Guidance in Fixed External Camera Network for Navigation in Crowded and Narrow Passages

ABSTRACT

Autonomous indoor service robots use the same passages which are used by people for navigation to specific areas. These robots are equipped with visual sensors, laser or sonar based range estimation sensors to avoid collision with obstacles, people, Continue reading

Mechatronic Development and Vision Feedback Control of a Nanorobotics Manipulation System inside SEM for Nanodevice Assembly

ABSTRACT

Carbon nanotubes (CNT) have been developed in recent decades for nanodevices such as nanoradios, nanogenerators, carbon nanotube field effect transistors (CNTFETs) and so on, indicating that the application of CNTs for nanoscale electronics may play Continue reading
