Abstract A station of AErosol RObotic NETwork Ocean Color (AERONET-OC) has been set on the Ariake Observation Tower Saga University April, 2018, for verification Second generation Global Imager (SGLI)/Global Change Mission-Climate (GCOM-C). Remote sensing reflectance (Rrs) observed by AERONET-OC was used SGLI. SGLI Version 1 data underestimated shortwave Rrs and (380) Rrs(412) were mostly negat...

Requirements for verifying spatial relations in robot workcell in terms of accuracy and repeatability are increasing. Improvements in the performance of industrial robots have extended the range of applications in to new fields in which flexibility, high payload, accuracy and repeatability are needed. To satisfy the requirements of overall geometric performance and flexibility in a robot system...

This paper presents a synthesis procedure for a two-degreeof-freedom spatial RR chain to reach an arbitrary end-effector trajectory. Spatial homogeneous transforms are mapped to 4× 4 rotations and interpolated as double quaternions. Each set of three spatial positions obtained from the interpolated task is used to define an RR chain. The RR chain that best fits the trajectory is the desired rob...

This paper reports about an experiment addressing different modes of natural language instructions in spatial human-robot interaction. The experimental setting involves a mobile robot equipped with an elementary dialogue system and human users unfamiliar with it who are required to achieve joint spatial reference with the robot either in spoken or in written mode. In addition, the robot’s outpu...

Task planning for mobile robots usually relies solely on spatial information and on shallow domain knowledge, like labels attached to objects and places. Although spatial information is necessary for performing basic robot operations (navigation and localization), the use of deeper domain knowledge is pivotal to endow a robot with higher degrees of autonomy and intelligence. In this paper, we f...

OBJECTIVE To evaluate peripheral respiratory system resistance and reactance (Rrs and Xrs, respectively) in obese individuals. METHODS We recruited 99 individuals, dividing them into four groups by body mass index (BMI): < 30.0 kg/m2 (control, n = 31); 30.0-39.9 kg/m2 (obesity, n = 13); 40.0-49.9 kg/m2 (severe obesity, n = 28); and ≥ 50.0 kg/m2 (morbid obesity, n = 13). Using impulse oscillom...

as a robot could be stable statically standing on three or more legs, a six legged walking robot can be highly flexible in movements and perform different missions without dealing with serious kinematic and dynamic problems. an experimental six legged walking robot with 18 degrees of freedom is studied and built in this paper. the kinematic and gait analysis formulations are demonstrated by an e...

We present a system for generating and understanding of dynamic and static spatial relations in robotic interaction setups. Robots describe an environment of moving blocks using English phrases that include spatial relations such as “across” and “in front of”. We evaluate the system in robot-robot interactions and show that the system can robustly deal with visual perception errors, language om...

A multi-spectral classification and quantification technique is developed for estimating chlorophyll a concentrations, Chl, in shallow oceanic waters where light reflected by the bottom can contribute significantly to the above-water remote-sensing reflectance spectra, Rrs(k). Classification criteria for determining bottom reflectance contributions for shipboard Rrs(k) data from the west Florid...

A technique to identify parameters of a robot dynamic model is presented in this paper. It is based on a batch adaptive control algorithm that, using a model of the robot dynamics, realizes a repetitive robot trajectory. The tracking error decreases due to a feedforward control input generated from the dynamic model. This feedforward input is computed after adaptation of the model parameters at...
