In the paper, an algorithm for the obstacle avoidance and a procedure for the role reassignment of robot formation control based on this algorithm are proposed. This algorithm contains an edge detector that is used to determine the position of the vertical edges of the obstacle in the environment. Meanwhile, a motion controller is also designed in this research based on the dynamic equation for...
This paper describes the Six-legged Integrated Locomotion and Manipulation Robot with an omni-directional walking mechanism and 4 d.o.f. manipulator. The walking mechanism consists of a parallel link mechanism connecting the two frames with three linear actuators, and this robot has six extendable legs and can move in any direction. The relative position and angle of the two frames are selected...
This paper describes a new local avoidance method for indoor mobile robots. The method uses a directional method named the Beam Method to improve the performance of a local obstacle avoidance approach called Curvature Velocity Method (CVM). The proposed Beam Method employs radial distances provided by the robot sensors to calculate the best one-step headings. The CVM uses this information to ca...
BACKGROUND Robot-assisted needle steering facilitates the percutaneous renal access (PRA) for their accuracy and consistency over manual operation. However, inaccurate image-robot correspondence and uncertainties in robot parameters make the needle track deviate from the intrarenal target. This paper aims to simplify the image-tracker-robot registration procedure and improves the accuracy of ne...
Behaviors, from simple to most complex, require a two-way interaction with the environment and the contribution of different brain areas depending on the orchestrated activation of neuronal assemblies. In this work we present a new hybrid neuro-robotic architecture based on a neural controller bi-directionally connected to a virtual robot implementing a Braitenberg vehicle aimed at avoiding obs...
In recent years, the use of omni-directional cameras has become increasingly more popular in vision systems and robotics. To date, most of the research relating to omnidirectional cameras has focussed on the design of the camera or the way in which to project the omni-directional image to a panoramic view rather than on how to process these images after capture. Typically images obtained from o...
