We demonstrate a conversational humanoid robot that allows users to follow their own dialogue structures. Our system uses a hierarchy of reinforcement learning dialogue agents, which support transitions across sub-dialogues in order to relax the strictness of hierarchical control and therefore support flexible interactions. We demonstrate our system with the Nao robot playing two versions of a ...

With the growth of computational power in recent years, complex autonomous robot systems have become a possibility. To increase their flexibility and adaptability, learning mechanisms are necessary for robot control. In this paper, I present two recent legged robot-systems that use machine-learning in their foothold-selection process. It was found that currently both systems have a number of is...

Abstract Recent advances in bionics have made it possible to create various tissue and organs. Using this cell culture technology, engineers developed a robot driven by three-dimensional cultured muscle cells (bioactuator)—a robot. For more applications, researchers been tissues organs with bio3D printer. However, printed printer not used for yet. The aim of our study is develop easy fabricatio...

Flexibility in agent scheduling increases the resilience of temporal plans in the face of new constraints. However, current metrics of flexibility ignore domain knowledge about how such constraints might arise in practice, e.g., due to the uncertain duration of a robot’s transition time from one location to another. Probabilistic temporal planning accounts for actions whose uncertain durations ...

Flexible manufacturing system is a system that is able to respond to changed conditions. In general, this flexibility is divided into two key categories and several subcategories. The first category is the so called machine flexibility which enables to make various products by the given machinery. The second category is routing flexibility enabling to execute the same operation by various machi...

Abstract In the face of Fourth Industrial Revolution (Industry 4.0), collaborative robots have become one key pillars development. Thanks to their sensors, they allow increased flexibility and safety while working in a shared space with humans. One such sensor is electronic skin (e-skin), which enhances human-robot collaboration through physical contact. This paper presents developed versatile ...

in this project guidance and control of underwater robot, including three engines and propeller attached to it, by fuzzy control has been investigated. fuzzy control is done based on human experience and requiered laws. the robot can also be controlled and guided by the user. this robot may be used in sea or swimming pool environment for finding goal point and locate in desired direction. in ad...

In this paper, a new method was proposed for the navigation of a mobile robot in an unknown dynamic environment. The robot could detect only a limited radius of its surrounding with its sensors and it went on the shortest null space (SNS) toward the goal. In the case of no obstacle, SNS was a direct path from the robot to goal; however, in the presence of obstacles, SNS was a space around the r...

To help people with impairment of lower extremity movement regain the ability to stand and walk, enhance limb function, this study proposes an anthropomorphic design electrically driven, lower-limb exoskeleton rehabilitation robot. The angular range robot’s motion was determined according characteristics targeted joints; robot given active–passive 12 degrees freedom. multi-degree-of-freedom hip...
