In industrialized countries, regional disparities in healthcare and welfare services, increased medical expense caused by aging societies and shortages of medical staff have become serious problems. In Sweden, it is expected that about 25% of Swedes population will be older than 65 years old by 2060 [1]. For this purpose, robot technology (RT) is expected to be an important key to find solution...

Recently, there has been a lot of interest concerning remote-control construction robot manipulation in hazardous operation environments including construction sites. However, there are problems involving the method of remote-control in unstructured work environments such as construction sites. In this study, an improved MFR system is described, which helps a human operator to easily install co...

this article presents an implementation of a reinforcement learning (rl) method for a snake like robot navigation. the paper starts with developing kinematics and dynamics model of a snake robot in serpentine locomotion followed by performing simulation and finishes with actual experimentation. first, gibbs-appell's method is used to obtain the robot dynamics. the robot is also modeled in simme...

in this paper, a new approach to modify cable tension measuring mechanism is described; furthermore, the constructed boards which amplify load cell output are introduced. this approach has some advantages including of providing feedback for motors, evaluating the robot’s ultimate load carrying capacity, improving the motor control system and estimating the vibrating deflections of the end effec...

This paper presents experimental analysis of wheeled mobile robots. Mathematical modelling of the mobile robot is presented. The mobile robots consist of an omni-directional and three differential drive mobile robots are tested and moved in given trajectories and the systematic errors of the robots are determined. A new method for omni-direction mobile robot was introduced in which the robot wa...

Nowadays digital watermarking has become an important technique, because using computational tools, digital contents can be copied and/or modified easily. At the beginning, the digital watermarking has been used for either copyright protection purpose or content authentication purpose. However, in many situations both purposes (copyright protection and content authentication) are required to be...

This paper aims to develop a writing robot by recognizing the speech signal from the user. The robot arm constructed mainly for the disabled people who can’t perform writing on their own. Here, dynamic time warping (DTW) algorithm is used to recognize the speech signal from the user. The action performed by the robot arm in the environment is done by reducing the redundancy which frequently fac...

Gait rehabilitation using body weight support on a treadmill is a recommended rehabilitation technique for neurological injuries, such as spinal cord injury. In this paper, a new robotic orthosis is presented for treadmill training. In the presented design the criteria such as low inertia of robot components, backdrivability, high safety and degrees of freedom based on human walking are conside...
