A Novel Wearable Haptic Controller for Teleoperating Robotic Platforms

Abstract

This letter presents a novel wearable haptic controller (WHC) system suitable for teleoperation of demolition machines and robotic platforms. With regard to existing operator controller unit composed by passive joysticks, the WHC has been designed to provide force feedback to the user, hence improving the user perfor- mance during the teleoperation of different robotic platforms and the interaction with the environment on the remote construction sites. The haptic feedback is provided through two compact parallel kinematic (CPK) interfaces that will be presented within the paper. The CPK implements a novel variant of the Delta kinematics which allows minimizing the radial encumbrance while preserving same operational workspace. In addition, we propose a new interaction modality that provides users the feeling of directly maneuvering the end-effector of the demolition machine. Finally, the architec- ture of the proposed system is presented and the results of some preliminary evaluation tests are discussed. The experiments have been performed in simulated environments and on a real machine

Nuevo vehículo aéreo autónomo estable por construcción: configuración y modelo dinámico

“…En la experimentación, se usaron las librerías embebidas desarrolladas por el laboratorio PERCRO *https://www.dropbox.com/sh/qdq35i1k2l1tqdq/AACOu4v-RR_AxI-DS4GfbLBIa?dl=0 (Perceptual Robotics) de Pisa, Italia (Villegas et al, 2015) para la familia Cortex-M7. Además, de forma similar a otros trabajos (Jacinto- Villegas et al, 2017), con la tarjeta mencionada se transfirieron las señales eléctricas del encoder para determinar la posición angular del anillo 2 y, con base en una diferenciación directa de la posición angular, se obtuvo su velocidad angular (Tilli and Montanari, 2001).…”

A Prospective Look: Key Enabling Technologies, Applications and Open Research Topics in 6G Networks

“…The use cases of TI have recently drawn significant research and industrial attention, as they are envisioned to have great potential to advance all aspects of our daily lives. As reported in the literature, TI has been adopted in numerous applications, such as VR and AR [278]- [287], healthcare [288]- [294], education [295]- [299], intelligent transportation [300]- [303], industry [304]- [307] and robotics [308]- [313]. Table 9 summarizes the envisioned applications of TI.…”

Wearable sensing devices for upper limbs: A systematic review

“…Since many of these manipulators have long kinematic chains, this kind of operation is highly inefficient in terms of the mental effort requested of the operator and the time needed to learn and to execute the task safely. 94 Therefore, an increasing number of wearable haptic controllers have been developed to provide force feedback for operators and to help operators achieve remote control of robotic platforms and interaction with the environment on remote construction sites. Several studies have demonstrated that the wearable devices with haptic feedback significantly improve operator performance in terms of reduced mental effort, reduced cognitive load, reduced number of collisions, and reduced time to execute the task.…”
