SnowEx is a winter airborne and field campaign designed to measure snow-water equivalent in forested landscapes. A major focus of Year 1 (2016–17) of NASA's SnowEx campaign will be an extensive field program involving dozens of participants from U.S. government agencies and from many universities and institutions, both domestic and foreign. Along with other instruments, two infrared (IR) sensors will...
In this paper, we present SPRinT (Smart Phone/Pad and Robot for Tele-operation and Tele-presence), a tele-presence robot for HRI controlled by a smart phone. It uses the projection display as a main communication channel between the local and remote users and we describe the interaction model for such an HRI scenario. We focus on the interaction model and interplay among the robot controlling (local)...
We demonstrate “Blurry (Sticky) Finger” in which one uses the unfocused blurred finger, sense of proprioception, to aim, point and directly select a distant object in the real world with both eyes open. We showcase two demo applications. The first illustrates the accuracy and usability of the proposed method with the target objects lying at a fixed depth on a monitor. The second is an AR based object...
In this paper, we suggest a PID controller for tracking the way-points of hovering autonomous underwater vehicle(HAUV). The PID controller is aimed at tracking arbitrary way-points and the way-points are established as the surveillance pathway for an offshore plant construction. Controllers are composed of a vertical plane controller and a horizontal plane controller. To verify the performance of...
In this paper, we propose a 1st person view and body motion based control method realized on a smart phone/pad called the Sprint (Smart Phone/Pad and Robot for Teleoperation and Tele-presence). The smart phone/pad is chosen, aside from its ubiquity and wide usage, for its mobility and rich media (sensor/display) capabilities. The key idea of Sprint is to have the operator control and interact by "posing"...
Detecting moving objects from an image sequence is challenging, especially when the camera is moving and the background varies significantly in every frame. In addition, classifying moving objects using only their appearances creates ambiguities in complex scenes. In this sense a Markov random field (MRF) approach is proposed incorporating a stereo vision-based structure-from-motion scheme in order...
In this poster, we present an experiment that compares three forms of interaction to study the user behavior with regards to the effects of camera view for in-situ robot control. We compared three hand-held interfaces with: (1) no camera view (Nominal), (2) a camera view/aim is always fixed toward the robot (Fixed) and (3) a camera view with user controlled aim (Free). The three approaches represent...
Participating in a play is one of integral curriculum for young children at nurseries and kindergartens. At the same time, it is not very easy to successfully run and manage a play for young children due to their low age and immaturity. We are exploring the use of a robot and augmented reality (AR) technology to assist the nursery teachers in hopes to alleviate the difficult and complicated task of...
This paper proposes an embedded system for measuring the water level on a river using a camera. One of the main problems of using a camera in water-level measurement is that the light reflection on water surface changes rapidly. To solve this problem, this paper uses the property that variation of light reflection on the ruler showing the scale is relatively smaller than on the water surface. To emphasise...
Radiation therapy with proton and heavy-ion beams has been better established lately and the patient throughput is increasing. Although the therapy beam is controlled with high accuracy, it is difficult to know the location of distal dose falloff in the body. If real-time monitoring of the location is realized, the treatment quality would be improved. We have developed an electron-tracking Compton...
Modern SoCs have the large scale and complexity. Modeling hardware architectures for SoCs usually requires pin-level and cycle-level descriptions by register transfer level(RTL). Hardware design at RTL takes too much effort to develop and simulate HDL code such as Verilog or VHDL. Therefore, a higher abstraction level is needed. Transaction level modeling (TLM) using SystemC addresses the limitations...
