Effect of force feedback on a bulldozer-type robot
Utilizing remote-controlled robots in damage restoration activities in disaster-affected areas such as those affected by a debris avalanche or an earthquake has significantly increased. Various types of remote-controlled robots have been successfully used along with construction machines in damage restoration activities in disaster-affected areas. Recently, a bulldozer-type robot removed the earth and sand deposited over a wide area because of a debris avalanche. To enable prompt damage restoration activities in disaster-affected areas, an efficient remote operation using robots is required. We study a remote-controlled bulldozer-type robot that moves objects using a system wherein the status of the stress applied on the bulldozer blade is provided as a force feedback to the operator. After conducting evaluation experiments, we could verify that the operating system providing force feedback to the operator shortened the operation time compared with the one that displayed visual information only on the operating screen.
Twisting for soft intelligent autonomous robot in unstructured environments
Significance Autonomy is crucial for soft robotics that are constructed of soft materials. It remains challenging to create autonomous soft robots that can intelligently interact with and adapt to changing environments without external controls. To do so, it often requires an analogical soft “brain” that integrates on-board sensing, control, computation, and decision-making. Here, we report an autonomous soft robot embodied with physical intelligence for decision-making via adaptive soft body-environment interactions and snap-through instability, without integrated sensing and external controls. This study harnesses physical intelligence as a new paradigm for designing autonomous soft robots that can interact intelligently with their environments, thus potentially reducing the burdens on the conventional integrated sensing, control, computations, and decision-making systems in designing intelligent soft robots.
La inseguridad jurídica en normas de contratación estatal
It is established by different studies that the issue of government procurement has been marred by several factors, the test objective to publicize these factors, we take as starting point the constant conflict between the branches of government to try and organize this subject; will collect and analyze diverse regulatory and case material in order to achieve evidence and demonstrate the different concepts of constant change that produces excessive regulation of the subject procurement and is in turn causing rapid changes that result in legal uncertainty for our law on the Contract Status.
