For the climbing rod object with large diameter variation and the need of obstacle crossing, this paper aims to propose a new embracing-type climbing robot named as EVOC-I robot.

The design philosophy and structural scheme are introduced. The kinematic analysis of embracing and telescoping mechanisms is carried out to provide the theoretical foundation for the effective climbing of the robot. Based on the prototype robot, three preliminary experiments are carried out to verify the effectiveness of the designed robot.

The theoretical and experimental analyses have verified the reasonability and effectiveness of the proposed robot design.

As the preliminary study, the prototype still need a lot of improvement. The experimental verification is also limited. Future work will focus on improving the design and increasing the theoretical analysis, especially increasing experimental study and designing the next generation of the rod climbing robot.

The designed climbing robot can be used for climbing the rod with variation diameter and flange obstacle, especially the lightening rod in the transformer substation.

The paper designs a new climbing robot that integrates the ability of large variation diameter adaptation and obstacle crossing.

Presents a numerical strategy for the aerodynamic analysis of large buildings, with an application to the simulation of the air flow within a telescope building. The finite element formulation is presented first, and then the methodology followed to obtain significant data from the calculations is described. The quality of the ventilation of the building is defined by the average residence times, and the feasibility of this ventilation by the actions created on the instruments and the general flow pattern.

The purpose of this paper is to show how the strategic selection of discursive and interactive strategies generates specific framings of an issue to advocate opposite positions, embodying a struggle of power between parties with their own agendas.

Drawing on literature within framing, digital issue arenas and critical discourse, this study analyses qualitative hypermodal data retrieved from two websites: Protect Mauna Kea, and Maunakea and Thirty Meter Telescope. These two websites frame the internationally renowned telescope’s construction on Mauna Kea Mountain in Hawaii from alternative perspectives.

On each website, frame articulation attempts to connect the event to specific concerns, values and beliefs in order to construct alternative versions of reality which can possibly fit with those of supporters. Simultaneously, this is reinforced by frame amplification concretized in selected discursive and interactive strategies that highlight or downplay the issue from particular perspectives.

The study offers a deep insight into the complexity and dynamic nature of framing, in particular into how framing can vary and compete across actors. It also responds to “the need for critical awareness of discourse in contemporary society” (Fairclough, 2010, p. 554) by revealing how the power positions of “challengers and powerholders” (Steinberg, 1998, p. 846) are discursively reproduced and reinforced through distinctive discursive and interactive strategies. Finally, this study adopts a critical approach to hypermodal discourse.

This paper aims to report on a design intervention at the Southern African Large Telescope (SALT) control room which resulted from a user-centred design approach intended to raise its usability.

Adapting a user-centred design approach, the observations and interviews revealed a number of weaknesses of the current control room design.

While most suggestions would require larger restructuring, the designers intervened with simple solutions resulting in the improved handling of many pieces of hardware. This study suggests that such design interventions hold the possibility to majorly improve the efficiency of the control room and thereby raise the potential outcome of such highly capital intense installations.

Thereby, this paper has immediate relevance to the astronomical field and the corresponding advancements in electronics, engineering and technology development.

The US Government is challenged to maintain pace as the world’s de facto provider of space object cataloging data. Augmenting capabilities with nontraditional sensors present an expeditious and low-cost improvement. However, the large tradespace and unexplored system of systems performance requirements pose a challenge to successful capitalization. This paper aims to better define and assess the utility of augmentation via a multi-disiplinary study.

Hypothetical telescope architectures are modeled and simulated on two separate days, then evaluated against performance measures and constraints using multi-objective optimization in a heuristic algorithm. Decision analysis and Pareto optimality identifies a set of high-performing architectures while preserving decision-maker design flexibility.

Capacity, coverage and maximum time unobserved are recommended as key performance measures. A total of 187 out of 10¹⁷ architectures were identified as top performers. A total of 29% of the sensors considered are found in over 80% of the top architectures. Additional considerations further reduce the tradespace to 19 best choices which collect an average of 49–51 observations per space object with a 595–630 min average maximum time unobserved, providing redundant coverage of the Geosynchronous Orbit belt. This represents a three-fold increase in capacity and coverage and a 2 h (16%) decrease in the maximum time unobserved compared to the baseline government-only architecture as-modeled.

This study validates the utility of an augmented network concept using a physics-based model and modern analytical techniques. It objectively responds to policy mandating cataloging improvements without relying solely on expert-derived point solutions.

This paper aims to describe bridge transported servo‐manipulator (BTSM) system, which was developed to overcome the limited workspace of the conventional mechanical master‐slave manipulators in a hot cell.

The BTSM system consists of four components: a transporter with a telescoping tubeset, a slave manipulator, a master manipulator, and a remote control system. The slave manipulator is able to move horizontally, transversely, and vertically by using the transporter.

The performance test of the BTSM system has been carried out in terms of basic functions such as force threshold, bilateral control and force reflection characteristic.

With respect to design characteristic, the BTSM system has the novel features in that the individual motor modules or the slave manipulator can be repaired in a fully remote manner in case of catastrophic failure. Also, a 3D viewing camera facilitates remote tasks giving human operators realistic environmental information.

This paper aims to report the first iteration on the Light Detection and Ranging (LIDAR) Engineering Model altimeter named HELENA. HELENA is a Time of Flight (TOF) altimeter that provides time-tagged distances and velocity measurements. The LIDAR can be used for support near asteroid navigation and provides scientific information. The HELENA design comprises two types of technologies: a microchip laser and low noise sensor. The synergies between these two technologies enable developing a compact instrument for range measurements of up to 14 km. Thermal-mechanical and radiometric simulations of the HELENA telescope are reported in this paper. The design is subjected to vibrational, static and thermal conditions, and it was possible to conclude by the results that the telescope is compliant with the random vibration levels, the static load and the operating temperatures.

The Asteroid Impact & Deflection Assessment (AIDA) is a collaboration between the NASA DART mission and ESA Hera mission. The aim scope is to study the asteroid deflection through a kinetic collision. DART spacecraft will collide with Didymos-B, while ground stations monitor the orbit change. HERA spacecraft will study the post-impact scenario. The HERA spacecraft is composed by a main spacecraft and two small CubeSats. HERA will monitor the asteroid through cameras, radar, satellite-to-satellite doppler tracking, LIDAR, seismometry and gravimetry.
