This work considers the problem of garment handling by a general household robot that focuses on the task of classification and pose estimation of a hanging garment in unfolding procedure. Classification and pose estimation of deformable objects such as garment are considered a challenging problem in...

A long history of first place awards in World RoboCup Rescue Robot competitions is Invigorating Robot Activity Project (iRAP) such as iRAP_PRO, iRAP_FURIOUS, iRAP_JUNIOR, and iRAP_ROBOT. In this paper, we would like to introduce and explain an autonomous system of our rescue robots for detection and...

Verbal Fluency Tasks (VFT) can be categorized into the Letter Fluency Task (LFT) that evaluates the ability to generate words starting with a particular letter, and the Category Fluency Task (CFT) that involves recall of words that belong to semantic categories. In this study, we investigated the differences...

This paper proposes a robotic grasp/assembly planner using a database of complex and skillful motion. In our proposed planner, if a skillful motion is included in the solution path, motion data included in the database is used. In this paper, we first explain the three-layered structure of the motion...

A Brushless DC (BLDC) motors synchronous control system based on the CANopen (a communication protocol and device profile specification for automatic embedded systems) protocol is proposed in this paper. Multi-motor control is popular in robot or automation system, and the synchronization is an important...

In this paper, a general method for constructing time-varying Lyapunov functions is provided for mechanical systems. A new class of time-varying Lyapunov functions is provided and sufficient conditions of uniform asymptotical stability are established. Different from the existing results on this subject,...

The convergent equilibrium of flocking agents is vital importance for their collective behavior, where flock guiding of hybrid agents, which are composed by both first and second order agents, can only be boiled down to the root node agents, is touched upon here. Both the theoretical analysis and the...

Embedded technologies are used everywhere. One of the educational materials to learn the embedded technologies is Arduino. When a beginner designs circuit, it is possible to design the circuit that damages Arduino itself or the modules on it. Therefore, this research implements an Arduino simulator that...

The design of biomimetic robot is one popular research. To achieve this goal, the reproduction of animal locomotion is mandatory. Animal locomotion is created by the activities of Central Pattern Generator (CPG). CPGs are neural networks capable of producing rhythmic patterned outputs without rhythmic...

Data-driven controller systems have been proposed to achieve the desired control performance without using any system identifications. The effectiveness of these control schemes has been shown through experimental results. For time-variant and nonlinear systems, it is important to evaluate the controller...

Safety is the most important issue while driving. Many traffic accidents occur because of insufficient safe distance. With the advancement of technology, there are cars with a front distance safety warning system. Some of them are with fixed safe distance regardless of the speed of the car. Other advanced...

We describe the design and implementation of a modular and distributed robot that physically simulates functioning of a 2-symbols Turing machine. The robot is constructed with Cubelets (small autonomous robot-cubes used for teaching basic robotics and programming for kids) and Lego® bricks (thus the...

Here we present experimental results of Electroencephalogram (EEG)-based Brain Computer Interface (BCI) for mobile robot control by means of Support Vector Machine (SVM) and Neural Network (NN). The authors had trained NNs using EEGs collected from subjects and verified the performance as BCI; however,...

In this study, the dual-rate sampled-data control system is designed, where the sampling interval of a plant output is an integer multiple of the holding interval of a control input. Because the discrete-time Linear Quadratic Integrator (LQI) is used for optimizing the discrete-time control performance,...

This paper describes an animated graphics-based training support method for bug fixing of Extended Place/transition Nets (EPNs), and illustrates a prototype tool that the core of the method has been implemented into. The prototype tool gives a trainee a faulty EPN and its animated graphics. The motion...

In general, a manipulation task can be composed of many skill primitives. Therefore, it is desirable to carry out plural visual sensing in most skill primitives; however, performing sensing all the time is difficult. In this paper, we propose the addition of importance ranks to the attribute of skill...
