In this research, redundant mechanism for RTC-CANopen Manager is investigated to improve reliability of the system built with RTC-CANopen. In the RTC-CANopen system, it becomes impossible to monitor the CANopen devices when RTC-CANopen Manager is down. RTC-CANopen Manager, it has frameworks both of RT-Middleware and CANopen and converts the interface for another subsystems. Thus, the robot constructed...
Disability of visual text reading has a huge impact on the quality of life for visually disabled people.One of the most anticipated devices is a wearable camera capable of finding text regions in natural scenes and translating the text into another representation such as speech or braille.In order to develop such a device,text tracking in video sequences is required as well as text detection.The device...
Disability of visual text reading has a huge impact on the quality of life for visually disabled people. One of the most anticipated devices is a wearable camera capable of finding text regions in natural scenes and translating the text into another representation such as sound or braille. In order to develop such a device, text tracking in video sequences is required as well as text detection. We...
This paper presents a path-tracking control method for a snake-like robot using screw drive mechanism. The operators are required to command only one unit in the head, then commands for the rest of the units are automatically calculated to track the path of the preceding units. Although the velocity commands for exact path tracking can be calculated using past command signals due to the omni-directional...
In this research, we aim at to develop design environment which allow changing a robotpsilas internal composition flexibly and easily by applying the RT-middleware. To achieve this, we propose to introduce the manager, named RTM-PnP manager, which supports plug and play for RT-component. This RTM-PnP manager that automatically negotiates and sets RT-middleware is investigated to reduce complex sets...
When an autonomous robot tries to find text in the surrounding scene using an onboard video camera, some duplicate text images appear in the video frames. To avoid recognizing the same text many times, it is necessary to decrease the number of text candidate regions for recognition. This paper presents a text capturing robot that can look around the environment using an active camera. The text candidate...
