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...

Inspired by the discovery of dimeric motor proteins capable of undergoing transportation in living cells, significant efforts have been expended recently to the fabrication of track-walking nanomotors possessing two foot-like components that each can bind or detach from an array of anchorage groups on the track in response to local events of reagent consumption. The central problem in fabricati...

A novel brain inspired cognitive system architecture of an active visual search model is presented. The model is multi-modular consisting of spatial and object visual processing, attention, reinforcement learning, motor plan and motor execution modules. The novelty of the model lies on its decision making mechanisms. In contrast to previous models, decisions are made from the interplay of a win...

The mirror mechanism allows the direct translation of a perceived (seen, felt, heard) action into the same motor representation of its related goal. This mechanism allows a direct comprehension of others' goals and motor intentions, enabling an embodied link between individuals. Because the mirror mechanism is a functional expression of the motor system, these findings suggest the relevance of ...

A study of grooming behaviors in Drosophila suggests a neuronal mechanism for how animals produce complex motor patterns from ordered interactions among modules of different motor acts. This mechanism may be a common one in many nervous systems.

A new type of motor that utilizes multilayer piezoelectric devices for electromechanical power conversion and mechanism of the strain wave gearing for generation of traveling motive force is proposed in this paper. The construction, basic operation, and torque generation mechanism of the motor are described. The motor can be operated in variable frequency. Experimental results on the prototype ...

Locally projecting inhibitory interneurons play a crucial role in the patterning and timing of network activity. However, because of their relative inaccessibility, little is known about their development or incorporation into circuits. In this report we demonstrate that the GABAergic R-interneuron circuit undergoes a reorganization in the chick embryo spinal cord between embryonic days 8 and 1...

Cholinergic neurons in the basal forebrain innervate discrete regions of the cortical mantle, bestowing the cholinergic system with the potential to dynamically modulate sub-regions of the cortex according to behavioral demands. Cortical cholinergic activity has been shown to facilitate learning and modulate attention. Experiments addressing these issues have primarily focused on widespread cho...

We modulated neural excitability in the human motor cortex to investigate behavioral effects for both hands. In a previous study, we showed that decreasing excitability in the dominant motor cortex led to a decline in performance for the contralateral hand and an improvement for the ipsilateral hand; increasing excitability produced the opposite effects. Research suggests that the ipsilateral e...
