WebDec 7, 2024 · We solve this inference problem using a factor graph. In order to incorporate tactile measurements in the graph, we need local observation models that can map high-dimensional tactile images onto a low-dimensional state space. Prior work has used low-dimensional force measurements or engineered functions to interpret tactile … WebMar 21, 2024 · In this paper, we investigate the problems of tactile pose estimation and manipulation for category-level objects. Our proposed method uses a Bayes filter with a learned tactile observation model and a deterministic motion model. Later, we train policies using deep reinforcement learning where the agents use the belief estimation from the …
Cross-modal repetition effects in the mu rhythm indicate tactile ...
WebMay 9, 2016 · A tactile two-alternative forced-choice (2AFC) discrimination task was then conducted in order to quantify the changes in tactile sensitivity during the observation of the same goal-directed actions. In agreement with the first experiment, the tactile perceived intensity was reduced only during the reaching phase. WebFig. 3: Deep tactile model predictive control: given the current tactile observation and a learned deep predictive model, we can predict the outcomes for different action sequences. We use this model within a model predictive control algorithm based on stochastic optimization. At each time-step the algorithm samples multiple potential action ... bob brislin masonry
Tactile Pose Estimation and Policy Learning for Unknown Object …
WebMar 8, 2024 · In this paper, we present a tactile-sensing based approach to this challenging problem of grasping novel objects without prior knowledge of their location or physical … WebMar 4, 2015 · This paper presents a global optimisation method where tactile and force sensing together with the robot's proprioceptive data are used to find an object’s pose. It is essential for a successful completion of a robot object grasping and manipulation task to accurately sense the manipulated object’s pose. Typically, computer vision is used to … WebIt has been suggested that tactile perception becomes less acute during movement to optimize motor control and to prevent an overload of afferent information generated during action. This empirical phenomenon, known as "tactile gating effect," has been associated … bob briscoe pottery
