A flexible cylindrical beam is used to design a six-axis column-type force and moment sensor for robotic applications, where accurate small measurements are required. One of the ends fixed, other remains free. rigid cover with mushroom shape placed at free end. This contact surface between object being touched, it transmits forces moments beam. The 12 miniature strain gauges strategically on measure by using simple model based classical theory elasticity. calibration method performed...

A critical operation for ship maintenance is periodical hull blasting before re-painting. Up to date some partial solutions exist like turbines vertical surfaces or water units striping. This paper presents the EFTCoR family of robots, designed by DSIE, that represent an integral solution achieves efficiency, safety and environmental requirements shipyards. The also shows results tests performed under real working conditions a brief summary architectural framework robotic systems development.

Cable-Driven Parallel Robots (CDPRs) are a special kind of parallel manipulator which use cables to control the position and orientation mobile platform or end-effector. The usage instead rigid links offer some advantages over their conventional counterparts. As can only pull, but not push, number (n) required command end-effector is always n+1. This configuration known as fully-constrained it most extended for CDPRs. Although CDPRs have many advantages, such ability cover large working...

Cable-driven parallel robots are a special type of robot in which an end-effector is attached to fixed frame by means several cables. The position and orientation the can be controlled controlling length These present wide range advantages, control algorithms required have greater complexity than those traditional serial robots. Measuring cable tension important task this as many rely on information. There well-known approaches measure robots, where trade-off between accuracy observed. This...

A method is proposed to achieve lateral stability of an autonomous bicycle with only the rotation front wheel. This can be achieved a classic controller. However, if energy consumption also has minimized, this solution not valid. To solve problem, adaptive controller been designed, which modifies its gains according bicycle’s forward velocity, adapting response minimum and satisfying design specifications. The study demonstrates efficiency control, achieving saving 73 . 8 % in trajectory...

This paper describes the simulation of movement control a one-degree-of-freedom articulated robot arm SCARAactuated by pair McKibben pneumatic artificial muscles. The muscle is actuator andemulates behavior biological muscles; due to its nonlinear behavior, there also need develop controlsystems for arms using this type actuator. Research begins with transfer function that represents, inmathematical language, arm’s joints; allows PID controller on transferfunction and generating data train...

Knock remains one of the main limitations for increasing efficiency in spark-ignition engines. The use certain alcohol–gasoline blends is an effective way to either mitigate or eliminate knock, allowing higher compression ratios, therefore Methanol and ethanol are alcohols commonly employed reducing due their octane number vaporization heat value. Major attention being paid recently butanol its with gasoline since they present similar characteristics gasoline; however, it was found be least...

Este artículo pretende dar a conocer un tipo de estructura doméstica poco habitual en la Oretania septentrional, como son los hornos destinados producción pan. El análisis su distribución, así sus dimensiones y características constructivas, revela que se trata estructuras más complejas, carácter colectivo o comunal, lo permite aproximarnos al conocimiento articulación interna principales oppida oretanos.

In the last few years, increasing concern about harmful effects of use fossil fuels in internal combustion engines has been observed. addition, limited availability crude oil driven interest alternative fuels, especially biofuels. context spark ignition engines, bioalcohols are great owing to their similarities and blend capacities with gasoline. Methanol ethanol have widely used, mainly due knocking resistance. Another alcohol is butanol, thanks its potential being produced as biofuel heat...

In the dynamic landscape of autonomous transport, integration intelligent transport systems and embedded control technology is pivotal. While strides have been made in development agents multi-agent systems, unique challenges posed by two-wheeled vehicles remain largely unaddressed. Dedicated strategies for these yet to be developed. The vertical balance an single-track vehicle a challenge engineering. This type unstable its behaviour changes with forward velocity. We designed scheduled-gain...

Abstract This article presents a new assembling for 2 degrees-of-freedom (DOFs) parallel robots executing rapid pick-and-place operations with low energy consumption. A conventional design of 2-DOF is based on five-bar mechanisms. Collisions between links are highly possible, restricting the end-effector workspace and/or increasing trajectory time to avoid collisions. In this article, an alternative preventing collisions presented. novel allows exploring difference four mechanism...
