On Saturday we spent a deal of time cleaning up the shed and whist it's not finished it's a lot closer to the way it looked some 15 years ago when I started using it.
There is still a lot to do, build another 2 bookcases and put them in the server room at the end of the shed. And then replace the blinds.

PB&J: Peanut Butter and Joints for Damped Articulation
Many bioinspired robots mimic the rigid articulated joint structure of the human hand for grasping tasks, but experience high-frequency mechanical perturbations that can destabilize the system and negatively affect precision without a high-frequency controller. Despite having bandwidth-limited controllers that experience time delays between sensing and actuation, biological systems can respond successfully to and mitigate these high-frequency perturbations. Human joints include damping and stif…

Human sensory-musculoskeletal modeling and control of whole-body movements
Coordinated human movement depends on the integration of multisensory inputs, sensorimotor transformation, and motor execution, as well as sensory feedback resulting from body-environment interaction. Building dynamic models of the sensory-musculoskeletal system is essential for understanding movement control and investigating human behaviours. Here, we report a human sensory-musculoskeletal model, termed SMS-Human, that integrates precise anatomical representations of bones, joints, and muscle…

Near Time-Optimal Hybrid Motion Planning for Timber Cranes
Efficient, collision-free motion planning is essential for automating large-scale manipulators like timber cranes. They come with unique challenges such as hydraulic actuation constraints and passive joints-factors that are seldom addressed by current motion planning methods. This paper introduces a novel approach for time-optimal, collision-free hybrid motion planning for a hydraulically actuated timber crane with passive joints. We enhance the via-point-based stochastic trajectory optimizatio…

We all keep our balance, our awareness of position in space, by analysing feedback we get from receivers in our skin and joints (proprioceptors) and from our visual assessment of our position in space. I am a below knee #amputee, so I have lost the position sensors in my foot, ankle, and leg. I gauge the location of my leg in space through my knee and secondarily, through my hip. 🧵

On the Practicability of Ceramic-Tiled Walls for Sound Absorption by Tuning Cavities
We present the practicality of structuring ceramic tiles for enhancing sound absorption on rigid walls. The cornerstone of our methodology is to structure walls with cavities so that walls effectively behave as heterogeneous absorbing surfaces over a large frequency bandwidth. Using this approach, ceramic tiled walls are developed by integrating tuned cavity structures based on Helmholtz resonators. Such a design leverages the empty joints between tiles to form resonator necks, while the space …
