FOLDAWAY DroneSense, a controller for haptic information encoding for drone pilots

Over the last decade, the number of drones has significantly increased. In parallel, researchers have started to investigate new human-drone interaction paradigms for a more natural and immersive piloting experience. The use of haptic feedback to establish a bidirectional interaction with a remote drone is a promising yet not fully exploited paradigm. In this article we introduce FOLDAWAY DroneSense, a portable controller with multi-directional force feedback for drone piloting. We also discuss four haptic interaction paradigms with the aim of boosting immersion and safety during teleoperation, and to simplify the training of first-time users

Quadcopter Flight Control Using a Non-invasive Multi-Modal Brain Computer Interface

Brain-Computer Interfaces (BCIs) translate neuronal information into commands to control external software or hardware, which can improve the quality of life for both healthy and disabled individuals. Here, a multi-modal BCI which combines motor imagery (MI) and steady-state visual evoked potential (SSVEP) is proposed to achieve stable control of a quadcopter in three-dimensional physical space. The complete information common spatial pattern (CICSP) method is used to extract two MI features to control the quadcopter to fly left-forward and right-forward, and canonical correlation analysis (CCA) is employed to perform the SSVEP classification for rise and fall. Eye blinking is designed to switch these two modes while hovering. Real-time feedback is provided to subjects by a global camera. Two flight tasks were conducted in physical space in order to certify the reliability of the BCI system. Subjects were asked to control the quadcopter to fly forward along the zig-zag pattern to pass through a gate in the relatively simple task. For the other complex task, the quadcopter was controlled to pass through two gates successively according to an S-shaped route. The performance of the BCI system is quantified using suitable metrics and subjects are able to acquire 86.5% accuracy for the complicated flight task. It is demonstrated that the multi-modal BCI has the ability to increase the accuracy rate, reduce the task burden, and improve the performance of the BCI system in the real world

Hybrid Brain-Computer Interface Systems: Approaches, Features, and Trends

Brain-computer interface (BCI) is an emerging field, and an increasing number of BCI research projects are being carried globally to interface computer with human using EEG for useful operations in both healthy and locked persons. Although several methods have been used to enhance the BCI performance in terms of signal processing, noise reduction, accuracy, information transfer rate, and user acceptability, the effective BCI system is still in the verge of development. So far, various modifications on single BCI systems as well as hybrid are done and the hybrid BCIs have shown increased but insufficient performance. Therefore, more efficient hybrid BCI models are still under the investigation by different research groups. In this review chapter, single BCI systems are briefly discussed and more detail discussions on hybrid BCIs, their modifications, operations, and performances with comparisons in terms of signal processing approaches, applications, limitations, and future scopes are presented

Development of Unmanned Aerial Vehicle (Quadcopter)With Real-Time Object Tracking

In the previous decade, Unmanned Aerial Vehicles (UAVs) have turned into a subject of enthusiasm for some exploration associations. UAVs are discovering applications in different regions going from military applications to activity reconnaissance. This thesis is an overview of a particular sort of UAV called quadrotor or quadcopter. Scientists are often picking quadrotors for their exploration because a quadrotor can precisely and productively perform assignments that future of high hazard for a human pilot to perform. This thesis includes the dynamic models of a quadrotor and model-autonomous control systems. It also explains the complete description of developed quadcopter used for surveillance purpose with real-time object detection. In the present time, the focus has moved to outlining autonomous quadrotors. Ultimately, it examines the potential applications of quadrotors and their part in multi-operators frameworks. The Unmanned aerial vehicle (Quadcopter) has been developed that could be used for search and surveillance purpose. This project comprised of both hardware and software part. The hardware part comprised of the development of unmanned aerial vehicle (Quadcopter). The main components that were used in this project are KK2 flight controller board, outrunner brushless DC motor, Electronic Speed Controllers (ESC), GPS (Global Positioning System) receiver, video transmitter and receiver, HD (High Definition) camera, RC (Radio Controlled) transmitter and receiver. Software part comprised of real-time object detection and tracking algorithm for detecting and tracking of human beings that were done with the help of Matlab software. After achieving the stable flight, the camera installed on the quadcopter would transmit a video signal to the receiver placed on the ground station. Video signal from the receiver would then be transferred to Matlab software for further processing or for tracking human beings using real-time object detection and tracking algorith
