Marrugo A.G.2020-03-262020-03-2620142014 3rd International Congress of Engineering Mechatronics and Automation, CIIMA 2014 - Conference Proceedings9781479979325https://hdl.handle.net/20.500.12585/9046This article describes the design and implementation of an electrogoniometer to measure joint angles during the execution of weight lifting exercises. The electrogoniometer consists of four microelectromechanical accelerometers connected to a microcontroller. The microcontroller is connected via USB to a computer. Preliminary tests show that the system offers high precision and accuracy at angle measurement. Error in the measured values is less than 0.3% when comparing to a commercial digital goniometer, and it is low cost. © 2014 IEEE.Recurso electrónicoapplication/pdfenghttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/conferenceObject10.1109/CIIMA.2014.6983436MechatronicsDesign and implementationsElectrogoniometersHigh-precisionJoint angleLow costsMeasured valuesMicro-electro-mechanicalWeight liftingAccelerometersinfo:eu-repo/semantics/restrictedAccessAtribución-NoComercial 4.0 InternacionalUniversidad Tecnológica de BolívarRepositorio UTB566828014005719016593957210822856
