The field of robotic perception and sensing is moving towards more accurate and efficient methods of data representation and processing. Researchers are exploring new techniques for transforming tactile sensor data into structured formats, enabling the use of high-level computation methods from other domains. Additionally, there is a growing interest in developing innovative sensing technologies, such as wireless strain and temperature sensing in 3D-printed metal structures, and multi-material 3D-printed tactile sensors with hierarchical infill structures. These advancements have the potential to improve the accuracy and reliability of robotic systems in various applications, including object recognition, locomotion, and maintenance. Noteworthy papers include:
- Simultaneous Calibration of Noise Covariance and Kinematics for State Estimation of Legged Robots via Bi-level Optimization, which introduces a bi-level optimization framework for joint calibration of covariance matrices and kinematic parameters.
- Proprioceptive Image: An Image Representation of Proprioceptive Data from Quadruped Robots for Contact Estimation Learning, which presents a novel approach for representing proprioceptive time-series data as structured two-dimensional images.
