Optimal Design of Piezoelectric Cantilevered Actuators for Charge-Based Self-Sensing Applications

2019

Charge-based Self-Sensing Actuation (SSA) is a cost and space-saving method for accurate piezoelectric based-actuator positioning. However, the performance of its implementation resides in the choice of its geometry and the properties of the constituent materials. This paper intends to analyze the charge-based SSA&rsquo

Roving Robots Gain from an Orientation Algorithm of Fruit Flies and Predict a Fly Decision-Making Algorithm

2014

Simple organisms like bacteria are directly influenced by momentary changes in concentration or strength of sensory signals. In noisy sensory gradients frequent zigzagging reduces the performance of the cell or organism. Drosophila melanogaster flies significantly deviate from a direct response to sensory input when orienting in gradients. A dynamical model has been derived which reproduces fly behaviour. Here we report on an emergent property of the model. Implemented in a robot, the algorithm is sustaining decisions between visual targets. The behaviour was consequently found in wild-type flies, which stay with a once-chosen visual target for considerable longer times than mutant flies wi…

OMNI-DRL: Learning to Fly in Forests with Omnidirectional Images

2022

Perception is crucial for drone obstacle avoidance in complex, static, and unstructured outdoor environments. However, most navigation solutions based on Deep Reinforcement Learning (DRL) use limited Field-Of-View (FOV) images as input. In this paper, we demonstrate that omnidirectional images improve these methods. Thus, we provide a comparative benchmark of several visual modalities for navigation: ground truth depth, ground truth semantic segmentation, and RGB images. These exhaustive comparisons reveal that it is superior to use an omnidirectional camera to navigate with classical DRL methods. Finally, we show in two different virtual forest environments that adapting the convolution to…

Social robots and therapeutic adherence: a new challenge in pediatric asthma?

2020

Social Robots are used in different contexts and, in healthcare, they are better known as Socially Assistive Robots. In the context of asthma, the use of Socially Assistive Robots has the potential to increase motivation and engagement to treatment. Other positive roles proposed for Socially Assistive Robots are to provide education, training regarding treatments, and feedback to patients. This review evaluates emerging interventions for improving treatment adherence in pediatric asthma, focusing on the possible future role of social robots in the clinical practice.

Virtual Prototyping of a Domestic Mobile Robot for Design and Navigation Optimisation

2004

This paper describes the application developed as part of the"PROSIGRAT" research project carried out by IKERLAN and Valencia University"s ARTEC group dealing with the use of Real Time simulation for services and products evaluation. The application consists of the development of a Real Time graphic simulation of a domestic mobile robot moving in a virtual environment and guided by a real physical navigation and control system, based on the HIL methodology concept. This is a clear example in which the Real Time simulation of a mechatronic system interacting with the environment leads to a reduction in the time-to-market of a new product that has been well tested and operates in a safe, reli…

HR1 Robot: An Assistant for Healthcare Applications

2022

According to the World Health Organization1,2 the percentage of healthcare dependent population, such as elderly and people with disabilities, among others, will increase over the next years. This trend will put a strain on the health and social systems of most countries. The adoption of robots could assist these health systems in responding to this increased demand, particularly in high intensity and repetitive tasks. In a previous work, we compared a Socially Assistive Robot (SAR) with a Virtual Agent (VA) during the execution of a rehabilitation task. The SAR consisted of a humanoid R1 robot, while the Virtual Agent represented its simulated counter-part. In both cases, the agents evalua…

Employees’ challenges and needs for reskilling when working with software robots

2022

Software robots are becoming increasingly adopted in different industries. The growing rate of automatization will affect more and more people and will result in changes in businesses of all sizes. Impacts can be observed at both the organizational and individual employee levels. A growing number of studies of software robots’ advantages and disadvantages on an organizational or industry-specific level have been carried out. However, there is limited knowledge about the employees’ perceptions of challenges and new skills needed when working with software robots. This study addresses this gap by using open-ended questionnaire responses from employees who have worked with software robots. Thi…
