Nonlocomotory Robotic Strategies for Dynamic Rotation Control in Terrestrial Robots: A Review

Advanced Robotics Research, EarlyView.
Terrestrial robots increasingly require rapid body rotation to maintain stability and agility in complex environments. This review shows nonlocomotory rotational control strategies that operate without ground contact, including reaction wheels, tails, bars, limbs, and thrusters.

Spin-orbit correlation and spatial distributions for spin-0 hadrons

Physics Letters B
The spin-orbit correlation in spin-0 hadrons can be investigated through the kinetic energy-momentum tensor form factor F˜q(t). We observe that the latter is also related to a torque about the radial direction, which we interpret as a chiral stress.
