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.

Journal of Applied Polymer Science, EarlyView.Optimized potential of rCB via DOE: recovered carbon black from end‐of‐life tires was assessed as a full substitute for conventional carbon black in IIR composites. DOE and response surface methodology optimized rCB loading, plasticizer, and sulfur contents. Hardness showed linear trends, while rupture energy was nonlinear.
