Sim To Real Transfer For Optical Tactile Sensing Deepai Deep learning and reinforcement learning methods have been shown to enable learning of flexible and complex robot controllers. however, the reliance on large amounts of training data often requires data collection to be carried out in simulation, with a number of sim to real transfer methods being developed in recent years. in this paper, we study these techniques for tactile sensing using the. In this paper, we study these techniques for tactile sensing using the tactip optical tactile sensor, which consists of a deformable tip with a camera observing the positions of pins inside this tip.
Pdf Sim To Real Transfer For Optical Tactile Sensing The images captured by vision based tactile sensors carry information about high resolution tactile fields, such as the distribution of the contact forces applied to their soft sensing surface. however, extracting the information encoded in the images is challenging and often addressed with learning based approaches, which generally require a large amount of training data. this article. The field of sim to real transfer has made important progress in addressing this, by enabling robots to be trained in simulation with no real world data at all [1], [9], [10]. in this paper, we study sim to real transfer for tactile sensing with domain randomisation [11], where simulation parame ters are randomised to provide robustness to the difference between dynamics in simulation and. Finally, we demonstrate the utility of our library and algorithms by evaluating the benefits of distillation and multimodal sensing for contact rich manipulation tasks, and most critically, performing sim to real transfer. Visual tactile sensing is a cutting edge technology that uses optical method to acquire high resolution tactile information by measuring the deformation of soft elastomeric materials [1], [2], which is popular in robotic manipulation [3], [4] and object recognition [5] tasks that rely on tactile information . in light of the fact that a majority of the existing advanced robotic manipulation.
