The progress of robotic technology in the last years paved the way for its application in the healthcare sector. In the light of demographic change and lack of nursing staff, telerobotic systems are a promising solution e.g. for homecare in rural areas or in quarantine stations to prevent dissemination of pathogens. This paper presents a user study investigating human performance when teleoperating...
Wireless teleoperation of field robots for maintenance, inspection and rescue missions is often performed in environments with low wireless connectivity, caused by signal losses from the environment and distance from the wireless transmitters. Various studies from the literature have addressed these problems with time-delay robust control systems and multi-hop wireless relay networks. However, such...
Recent advancements in different fields such as computing technologies and fast communication channels has lead to increased interest in master-slave systems and their various applications for teleoperation field. When investigating master-slave systems, the general approach points towards better performance, where major concerns are stability and transparency of the system. This has lead to a large...
This paper presents a new Haptic Rate-Position controller, which allows manipulating a slave robot in a large workspace. Haptic information is displayed to the user so as to be informed when a change in the operation mode occurs. This controller allows performing tasks in a large remote workspace by using a haptic device with a reduced workspace such as Phantom. Experimental results have been carried...
The modeling of a modular robot system is complex due to its capability of changing and forming countless robot configurations with a set of modules. The greater the number of modules added to the structure, more complicated is the robot and its modeling. A methodology to represent modular robot configurations as a fixed shape robot is presented. The equivalent model is obtained through the characterization...
