Wearable DAQ (Data Acquisition System) for Measurement of R.U.L.A.(Rapid Upper Limb Assessment) Rating of Vehicles

R.U.L.A.(Rapid Upper Limb Assessment)is a measure of the ergonomic risk factors developed to evaluate the exposure of individual workers to upper extremity Musculoskeletal Disorders. Since a driver has to drive for long hours while maintaining his composure and comfort, this can be ensured by following R.U.L.A as ergonomics is one of the most crucial factors for chassis design of vehicles. R.U.L.A. calculation is usually performed using software only, in this paper we have designed a wearable data acquisition system which measures posture and angle values of the driver's body and gives us an accurate R. U. L.A. rating of the driver in order to validate and compare the software simulation values as obtained on Catia.
