Sampling, Mobility, and Anchoring in Small‐Body Sampling Robots: A Comprehensive Review
SmartBot, EarlyView.Small‐body sampling robots are exploration systems that perform contact, sampling, and stable operations on microgravity bodies such as asteroids and comets. The authors review representative robot architectures and key technologies, focusing on the mechanisms, evolution, and coupling of sampling, mobility, and anchoring.

An inverse kinematics algorithm for a highly redundant variable-geometry-truss manipulator [PDF]
A new class of robotic arm consists of a periodic sequence of truss substructures, each of which has several variable-length members. Such variable-geometry-truss manipulator (VGTMs) are inherently highly redundant and promise a significant increase in ...

Bath Vibration During Open Eye Formation in a Physical Model of a Steelmaking Ladle
steel research international, EarlyView.Using a physical model, this study shows that vibration measurements reliably predict open eye size in steelmaking ladles, offering a practical alternative to visual monitoring. Vessel vibrations stabilize faster than the open eye, except at high frequencies near the bottom.

General-Weighted Least-Norm Control for Redundant Manipulators under Time-Dependent Constraint
International Journal of Advanced Robotic Systems, 2015 Previous research dealing with constrained kinematic redundancy problems focuses on manipulators with time-independent constraints. This paper extends the general-weighted least-norm (GWLN) method to manipulators with time-dependent constraints by ...

Fuzzy logic control of telerobot manipulators [PDF]
Telerobot systems for advanced applications will require manipulators with redundant 'degrees of freedom' (DOF) that are capable of adapting manipulator configurations to avoid obstacles while achieving the user specified goal.

Optimal redundancy resolution for kinematically redundant parallel manipulators
, 2020 Bu çalışmada kinematikçe artıksıl olan paralel manipülatörlerin artıksıllık çözümlemesi bir eniyileştirme problemi olarak ele alınmıştır. Ortaya çıkan eniyileştirme problemi evrensel olarak melez genetik algoritma kullanılarak çözülmüştür. Bu algoritma örnek olarak dört serbestlik dereceli bir düzlemsel paralel manipülatöre uygulanmıştır.

Kinematic Control of Redundant Knuckle Booms
International Journal of Forest Engineering, 2009 The Swedish forestry industry competes on an international market; because raw material is more expensive than in other parts of the world, the chain from the stump to the industry needs to be very effective. One part in this chain is cutting and transporting trees from the forest to the landing area for further transportation with trucks to the paper ...

CAAI Transactions on Intelligence Technology, EarlyView.ABSTRACT Repetitive motion planning (RMP) for redundant manipulators with high convergent precision becomes an intense research topic due to its more degrees of freedom. In this paper, a specific zeroing neural dynamics (SZND) model for the RMP is first set up via zeroing neurodynamics.

Resolution of seven-axis manipulator redundancy: A heuristic issue [PDF]
An approach is presented for the resolution of the redundancy of a seven-axis manipulator arm from the AI and expert systems point of view. This approach is heuristic, analytical, and globally resolves the redundancy at the position level.
