Abstract Experts predict that future robot applications will require safe and predictable operation: robots will need to be able to explain what they are doing to be trusted. To reach this goal, they will need to perceive their environment and its object to better understand the world and the tasks they have to perform. This article gives an overview of present advances with the focus on options to learn, detect, and grasp objects. With the approach of colour and depth (RGB-D) cameras and the advances in AI and deep learning methods, robot vision has been pushed considerably over the last years. We summarise recent results for pose estimation of objects and work on verifying object poses using a digital twin and physics simulation. The idea is that any hypothesis from an object detector and pose estimator is verified leveraging on the continuous advances in deep learning approaches to create object hypotheses. We then show that the object poses are robust enough such that a mobile manipulator can approach the object and grasp it. We intend to indicate that it is now feasible to model, recognise and grasp many objects with good performance, though further work is needed for applications in industrial settings.

AbstractBetter handling of neurological or neurodegenerative disorders such as Parkinson’s Disease (PD) is only possible with an early identification of relevant symptoms. Although the entire disease can’t be treated but the effects of the disease can be delayed with proper care and treatment. Due to this fact, early identification of symptoms for the PD plays a key role. Recent studies state that gait abnormalities are clearly evident while performing dual cognitive tasks by people suffering with PD. Researches also proved that the early identification of the abnormal gaits leads to the identification of PD in advance. Novel technologies provide many options for the identification and analysis of human gait. These technologies can be broadly classified as wearable and non-wearable technologies. As PD is more prominent in elderly people, wearable sensors may hinder the natural persons movement and is considered out of scope of this paper. Non-wearable technologies especially Image Processing (IP) approaches captures data of the person’s gait through optic sensors Existing IP approaches which perform gait analysis is restricted with the parameters such as angle of view, background and occlusions due to objects or due to own body movements. Till date there exists no researcher in terms of analyzing gait through 3D pose estimation. As deep leaning has proven efficient in 2D pose estimation, we propose an 3D pose estimation along with proper dataset. This paper outlines the advantages and disadvantages of the state-of-the-art methods in application of gait analysis for early PD identification. Furthermore, the importance of extracting the gait parameters from 3D pose estimation using deep learning is outlined.
