Humanoid robots are still in a process of the evolution. We are trying to develop a next-generation which have safety, flexibility and multiplicity of uses. A Shoulder structure is one of the keystone, because it controls arms and end effectors and it have direct contact with humans and daily life environments. We have designed new shoulder structure following the scapula-collarbone structure for a muscle-driven humanoid robot named "Kojiro" (Fig. 1) [1]. We consider that the scapula-collarbone structures have the following merits, 1)wide range of movement, 2)flexible shoulder like humans, 3)safety from the driving system, 4)allowing space for a lot of parts inside the thorax. The shoulder structure is consisted of scapula, collarbone, upper-arm and thorax. We have devised the spherical shape thorax and scapula structure which realizes desired scapula motions. In this paper, we describe the design process and operation test of the shoulder structure.

As personal autonomous mobility is getting to be more widely adopted, it is more important to consider comfortability of stuffs and persons carried by such mobility. In this work, we define the comfort of a trajectory as forces, specifically, translational force, received to objects carried by a robot while following the trajectory by measuring impulse. To maximize such a comfort, we propose a novel, kinodynamic comfort path planning method based on our definition of comfort. Our work is based on direct collocation method for handling our non-convex objective function. We also introduce Bidirectional Obstacle Detection( BOD) that identifies the distances along the perpendicular directions to the trajectory. This is mainly designed for avoiding obstacles while minimizing forces causing discomfort. Our experimental results show that our method can compute trajectories whose comfort measures can be up to 18 times higher than those computed by prior related objectives, e.g., squared velocity used for generating smooth trajectory.

The paper analyzes network-centric methods for control cyberphysical objects. Cyber-physical objects interact with each other by transmitting information via computer networks. In the framework of this cyber-physical approach proposed a structure for interactive control system for on-surface robot from International Space Station. This system implements the circuit-torque sensitization algorithms for network delays while transferring data over the computer telecommunication network.

The authors suggest that present capabilities forbid early introduction of the fully autonomous (thinking) robot except in such limited circumstances that misoperation would not have serious consequences. They claim that the nextgeneration of intelligent robotic devices will be 'smart' teleoperators, with provision for human override of either preprogrammed or AI (artificial-intelligence)-system-generated operating commands. It is predicted that such systems will be capable of 100% human direction whenever machine intelligence cannot be utilized. In space applications, both for EVA and IVA (extra- and intravehicular activity), this human-control with back up capability will minimize accidents and provide last-resort control of vital functions. The authors discuss the architecture, capabilities, and technologies associated with the design and implementation of such systems.

Hardware acceleration can revolutionize robotics, enabling new applications by speeding up robot response times while remaining power-efficient. However, the diversity of acceleration options makes it difficult for roboticists to easily deploy accelerated systems without expertise in each specific hardware platform. In this work, we address this challenge with RobotCore, an architecture to integrate hardware acceleration in the widely-used ROS 2 robotics software framework. This architecture is target-agnostic (supports edge, workstation, data center, or cloud targets) and accelerator-agnostic (supports both FPGAs and GPUs). It builds on top of the common ROS 2 build system and tools and is easily portable across different research and commercial solutions through a new firmware layer. We also leverage the Linux Tracing Toolkit nextgeneration (LTTng) to enable low-overhead real-time tracing and benchmarking of accelerated ROS 2 systems. To demonstrate the acceleration enabled by this architecture, we use it to deploy a ROS 2 perception computational graph on a CPU and FPGA. We also employ our integrated tracing and benchmarking to analyze bottlenecks, uncovering insights that guide us to improve FPGA communication efficiency. In particular, we design an intra-FPGA ROS 2 node communication queue template and use it in conjunction with FPGA-accelerated nodes to achieve a 24.42% speedup over a CPU.

Increasing efficiency by improving locomotion methods is a key issue for underwater robots. In this paper, we investigate the power consumption of different underwater robotic systems and compare the energy efficiency of the different robots depending on the desired motion. In particular, we compare the energy efficiency of underwater snake robots, which can provide both inspection and intervention capabilities and thus are interesting candidates for the nextgeneration inspection and intervention AUVs, with those of the widely used robots for subsea operations which are the remotely operated vehicles (ROVs). In order to compare the energy efficiency of underwater snake robots with the energy efficiency of the ROVs, a simulation study is performed comparing the total energy consumption and the cost of transportation of underwater snake robots and ROVs. The simulation results show that with respect to the cost of transportation metric and the total energy consumption the underwater snake robots are more energy efficient for all the compared motion modes compared to the ROVs.
