The authors proposed a car transportation system, iCART (intelligent Cooperative Autonomous Robot Transporters), for automation of mechanical parking systems by two mobile robots. However, it was difficult to downsize the mobile robot because the length of it requires at least the wheelbase of a car. This paper proposes a new car transportation system, iCART II (iCART - type II), based on “a-robot-for-a-wheel” concept. A prototype system, MRWheel (a Mobile Robot for a Wheel), is designed and downsized less than half the conventional robot. First, a method for lifting up a wheel by MRWheel is described. In general, it is very difficult for mobile robots such as MRWheel to move to desired positions without motion errors caused by slipping, etc. Therefore, we propose a follower's motion error estimation algorithm based on the internal force applied to each follower by extending a conventional leader-follower type decentralized control algorithm for cooperative object transportation. The proposed algorithm enables followers to estimate their motion errors and enables the robots to transport a car to a desired position. In addition, we analyze and prove the stability and convergence of the resultant system with the proposed algorithm. In order to extract only the internal force from the force applied to each robot, we also propose a model-based external force compensation method. Finally, proposed methods are applied to the car transportation system, the experimental results confirm their validity.

We propose a novel car transportation system termed as iCART (i__-ntelligent c__-ooperative a__-utonomous r__-obot t__-ransporters). This system transports cars using two robots that move in coordination. This car transportation system can transport cars of any size and offers various functions such as parking, valet parking, towing service, and the transportation of cars inside a factory, onto a ferry, and in complicated parking areas. The robots in this car transportation system comprise three modules: the mobile base module, the lifter module, and the connecting module. This paper describes the details of the operation mechanism and the basic algorithm of each module. A leader-follower-type distributed motion control algorithm is applied to the proposed system and is used in an experiment performed to verify the validity of its function.

In this article, we propose a cycling wheelchair controlled by the servo brake. The cycling wheelchair is a pedal-driven system and support the moving of many patients with impairment of their lower extremities. This wheelchair has a potential as a mobility assistive device to improve the daily activities. However, there are several barriers to use the cycling wheelchair in an outdoor environment. Especially, on downward slopes, patients cannot properly apply the braking torque to the pedal. This inability to slow the wheelchair presents a dangerous situation. On the other hand, the cycling wheelchair is an effective rehabilitation device, so that many patients to use it as an indoor training device. For rehabilitation, the device should have functions to not only apply the load to the patients but also encourage the patients to train. In this study, we propose a new cycling wheelchair for supporting both outdoor moving and indoor training. The cycling wheelchair has servo brake system and interface to connect the personal computer. By controlling the brake system, the velocity control in the outdoor environment is realized. In addition, the braking force can apply the load to the patients for their rehabilitation in the indoor environment, and they can also enjoy the computer game and virtual environment by using the cycling wheelchair as an interface such as key bode and joystick.

In this study, we propose a steering control method for a cycling wheelchair. The commercially available cycling wheelchair is a pedal-driven system like a bicycle and the paraplegia and hemiplegia patients can move the wheelchair based on the pedaling force, if they can move their legs slightly by themselves. The user can also change the motion direction of the cycling wheelchair by using the steering handle. However, the right and left turnings are perceived differently while operating the steering handle and the steering operation is required a large torque because of the hardware problems of the cycling wheelchair. To overcome these problems, we propose a new hardware of the cycling wheelchair and its steering motion control method by using servo brakes. The proposed method is applied to the developed new cycling wheelchair and the experimental results illustrate the validity of the system.

In this research, we develop a Passive Dance partner Robot (PDR) for realizing the effective human-robot cooperation. Different from the active-type robot with servo motors, passive robot is controlled by the servo brakes attached to the wheels of the robot and its driving force is the actual force/moment applied by a human. In this paper, we propose a motion control algorithm of the PDR for realizing the ballroom dance with a male dancer based on the estimation of the next dance step intended by him.

<p>We propose a novel method for motion guidance by creating a motion direction by using multiple vibration stimulations. In order to create the motion direction, we utilize a vibratactile illusion called Phantom Sensation. In this method, moving vibration stimulation on the user's skin, which is generated by controlled the position of Phantom Sensation, creates the motion direction. In this paper, we guide the user's wrist to the desired position using our proposal method. We control the produced direction and transmission time by the relationship between current position and desired position. We recognize that they can arrive at a desired position to move their wrist obeying the produced direction.</p>
