From IT infrastructure to application technology: make, connect, use

The rapid growth of devices (smartphone, tablets, robots, wearables, etc.) and the Internet has increased the amount of information that is being produced and accessed by society. In order to better utilize the data produced from millions of devices and systems, we are conducting research and development in a wide range of fields at the interface between information technologies and human factors. Our mission is to engage and enrich the public through the research and development of intelligent systems combining computational and physical capabilities for human use. A key component of our mission is making new discoveries in the hardware and software that interacts with physical devices to sense and change the state of the real world. Our discoveries will lead to industry innovations and contribute to the advancement of society by facilitating the interaction of humans with cyber-physical systems.

Demonstration of the Effectiveness of Motion-Assist Devices for Sensorimotor Learning Using a Rat Experimental Model

AIST has demonstrated that learning effectiveness can be improved by assisting stimulus-response motion in a timely manner. Air-pressure stimuli were applied to one forepaw of a rat. The number of days for the rat to learn the correct forepaw was investigated by varying the timing of intervention and the target forepaw for intervention (on the correct response side or the incorrect response side). The learning time was less when intervention produced an incorrect motion than when intervention produced a correct motion. The intervention was effective when applied just before the rat responded spontaneously.

Layer 2-based Wireless Relay Network for Robot Control under Non Line-of-Sight Environments

AIST and NICT have demonstrated remote operation and monitoring of a small unmanned ground vehicle beyond the line-of-sight from the operator via a hovering drone up in the sky. The control communication link is continuously maintained with the layer 2-based fast access control technique, even when the relay route frequently changes due to the movement of the robots. The conventional techniques have problems in continuity every time the relay route changes and the communication link is disconnected, which results in momentarily losing control of the robot. This technology will help to achieve tough robot systems operational in poor radio propagation environments caused by obstacles.

Towards realization of intelligent systems that robustly work in various environments

The mission of Intelligent Systems Research Institute is to promote fundamental long-term research whose outcomes for the society have been examined be thorough investigations. The institute studies intelligent systems technologies that are defined by smart information processing and robotics to assist human behaviors, and seeks their basic principles, elemental technologies and system architectures to contribute the realization of the sustainable society and the creation of novel industries.
Recently, we focus on R&D of technologies of sensing and recognition of 3D environments, motion and grasp planning, and locomotion in unstructured environments. R&D of applications of intelligent systems collaborating with companies are highly encouraged, including, but not limited to, in manufacturing, service, maintenance of infrastructure and executing complex tasks in dangerous, degraded, human-engineered environments.
