The heart rate (HR) is a widely used clinical variable that provides important information on physical user's state. One of the most commonly methods for ambulatory HR monitoring photoplethysmography (PPG). PPG signal retrieved from wearable devices positioned wrist can be corrupted when user performing tasks involving motion arms, wrist, and fingers. In these cases, obtained altered as well. This problem increases trying to monitor people with autism spectrum disorder (ASD), who are very...

This article presents a new application of parallel robots as underwater vehicles.
