This paper presents an application for controlling the orientation of a 6 degrees-of-freedom serial manipulator with the help of a digital compass. The goal of this research ss to obtain a flexible system in which the robot operator is not constrained to use predefined programs. The system is designed for tasks in which the operator does not require solid programming knowledge. The control system contains a digital compass and a micro-computer with low power consumption which can be easy manipulated by an operator or by another robot. The connection between the control system is made via the TCP/IP protocol. The system has been tested and calibrated in order to obtain the proper setup for a smooth robot motion.
The need of human helping robots is imposed by the nowadays trend towards protecting the physically impaired people. New researches in this area have arisen in the past years. In the next few lines an overview of the state of the art in this domain will be made. The main objective in this paper is to demonstrate the simultaneous localization for a wheelchair, using elecromiographic signals. So far the research on robots used for helping disabled people has been focusing mainly on replacing limbs by robotic prosthesis or surgery
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
