Advanced Robotics Research, EarlyView.This work presents a state‐adaptive Koopman linear quadratic regulator framework for real‐time manipulation of a deformable swab tool in robotic environmental sampling. By combining Koopman linearization, tactile sensing, and centroid‐based force regulation, the system maintains stable contact forces and high coverage across flat and inclined surfaces.

Density-Dependent Length Contraction with Angular Spin Torque
[This content is now fully covered by the main Apollonian theory of everything] A flat-spacetime scalar model where gravity emerges as radial ruler contraction along the line-of-sight: s = max(1 - κ_eff ∫ ρ ds, 0.01), with κ_eff = 7.39 × 10^5 m² kg^{-1} (Gaia DR3 calibrated) scaling as κ_eff ∝ 1/(1 + ρ/ρ_crit)^2, ρ_crit = 10^{-24} kg m^{-3 ...

Liquid Crystalline Elastomers in Soft Robotics: Assessing Promise and Limitations
Advanced Robotics Research, EarlyView.Liquid crystalline elastomers (LCEs) are programmable soft materials that undergo large, anisotropic deformation in response to external stimuli. Their molecular alignment encodes directional actuation in a monolithic structure, making them long‐standing candidates for soft robotic systems.
