Unmanned Aerial Vehicles (UAVs) have shown great potential in agriculture and are increasingly being developed for agricultural use. There are still a lot of experiments that need to be done to improve their performance and explore new uses, but experiments using UAVs are limited by many conditions like weather and location and the time it takes to prepare for a flight. To promote UAV remote se...

This paper addresses the problem of on-board estimation of the state and/or the velocity components of an unknown leader by open-loop control of a single camera installed on the follower aircraft. Unlike the conventional pan-tilt gimbal, a custom-built gimbal is assumed that permits translational movement of the camera. The only information about the unknown leader is deduced from its bearing a...

In this paper we present a fast power line detection and localisation algorithm as well as propose a high-level guidance architecture for active vision-based Unmanned Aerial Vehicle (UAV) guidance. The detection stage is based on steerable filters for edge ridge detection, followed by a line fitting algorithm to refine candidate power lines in images. The guidance architecture assumes an UAV wi...

The research reported in this paper examined the design and control of a gimbal for solar eclipse tracking video recording. required 3 axes rotation to allow full range motion. Utilizing individual brushless motors each ensures minimum rotational requirements on axes. In controlling gimbal, both mathematical visual method was utilized. is modeled version what currently used array pointing. look...

When tracking small UAVs and drone targets in cloud clutter environments, MWIR sensors are often unable to track continuously. To overcome this problem, the SWIR sensor is mounted on same gimbal. Target uses information fusion or selectively applies from each sensor. In case, parallax correction using target distance used. However, it difficult apply existing method because laser rangefinder's ...

In this paper we describe an experiment aimed at determining the most effective and natural orientation of a virtual guide that gives route directions in a 3D virtual environment. We hypothesized that, due to the presence of mirrored gestures, having the route provider directly face the route seeker would result in a less effective and less natural route description than having the route provid...

Problem-Based Learning (PBL) is a popular approach to instruction that supports students get hands-on training by solving problems. Question Pool websites (QPs) such as LeetCode, Code Chef, and Math Playground help PBL supplying authentic, diverse, contextualized questions students. Nonetheless, empirical findings suggest 40% 80% of registered in QPs drop out less than two months. This research...

An initial startupmethod for a spacecraft actuated by a pyramidal arrangement of variable-speed controlmoment gyroscopes is developed. The method provides closed-loop internal momentum tracking control to enable the flywheels to start from rest and reach desired wheel speeds. The proposed controller functioning as a variable-speed control moment gyroscope steering law is developed in terms of t...

the application of inertial stabilization system is to stabilize the sensor’s line of sight toward a target by isolating the sensor from the disturbances induced by the operating environment. The aim of this paper is to present two axes gimbal system. The equations of gimbals motion are derived using Lagrange equation considering the base angular motion and mass unbalance. The stabilization loo...
