Sensor-based navigation is one of the most important researches for mobile robots domain and then there are many research works for sensor-based navigation. We propose the insects inspired landmark navigation to pinpoint the target position in this paper. There exit several research works such as snapshot model and average landmark model which request the absolute bearing information (compass) ...

Biological inspired robotics is an area experiencing an increasing research and development. In spite of all the recent engineering advances, robots still lack capabilities with respect to agility, adaptability, intelligent sensing, fault-tolerance, stealth, and utilization of in-situ resources for power when compared to biological organisms. The general premise of bio-inspired engineering is t...

The design of a relatively new genre of aerial robots — a full-scale, bird-like flapping wing flying robot — is analyzed, modelled and validated through real experiments in this paper. Quaternions are used instead of Euler angles in the dynamical model to represent the flying robot orientation in 3D space in order to realize smoother rotational manoeuvres using spherical linear interpolation. E...

Multi-vehicle aerial robots present great potential in accomplishing manipulation tasks, because of their high payload capacity and full manipulability 3-dimensional space. Belonging to this class robots, the Flying Parallel Robot (FPR) is an architecture where a moving platform supported collectively by team quadrotors with passive kinematic chains. While modelling control FPR free space has b...

The development of small, active robots is built around an iterative process of design, modeling, and verification. Accurate knowledge of vehicle position and velocity is crucial to verification, and so is essential for closing the loop of this iterative process. In this paper we present a method for detecting robust fiducials from a video of a robot moving in the image plane. We combine image ...

This paper introduces the application of a sensor network to navigate a flying robot. We have developed distributed algorithms and efficient geographic routing techniques to incrementally guide one or more robots to points of interest based on sensor gradient fields, or along paths defined in terms of Cartesian coordinates. The robot itself is an integral part of the localization process which ...

This study aimed to evaluate the effect of rootstocks on fruit sugars, organic acids, and carotenoids. The contents of sugars and organic acids in fruits were determined by HPLC. Total acidity (TA), total soluble solids (TSS), and pH value of the juice were also evaluated. Total carotenoids and chlorophylls contents were measured using a spectrophotometer. The content of ethylene in fruits was ...

During servicing operations, free-flying robots equipped with robotic arms are required to operate without disturbing the nearby environment through unwanted base oscillations. We present underlying theory, kinematic control software, and experimental results of a three-dimensional free-flying robot prototype able to follow a given trajectory with its end-effector while base movements are minim...

We present a sensor network based indoor localization system that uses ultrasonic distance measurements for realtime localization of flying four-rotor robots. Such quadrocopters are on-board sensor controlled systems. They are very sensitive to lateral drifts, which cannot be compensated by mounted sensors. In our work, we provide a framework for time-of-flight based localization systems relyin...
