Dual-space adaptive synchronization control of redundantly-actuated cable-driven parallel robots

, 2020
For cable-driven parallel robots, a mobile platform is linked to a fixed frame by multiple flexible cables that are winded by winches, and the main application for such robots is to achieve high-precision motion in a large workspace.

Achieving ultrahigh volumetric performance of graphene composite films by an outer–inner dual space utilizing strategy

, 2020
Graphene films often suffer from low gravimetric capacitance at high density due to low space utilization, resulting in undesirable volumetric performance.

Multi-objective configuration optimization for coordinated capture of dual-arm space robot

Acta Astronautica, 2020
Dual-arm space robot is a promising autonomous system to remove the increasing space debris actively. Due to its limited on-orbit energy, dual-arm space robot should approach and capture the target with minimum time and base disturbance.

Reinforcement learning in dual-arm trajectory planning for a free-floating space robot

, 2020
A free-floating space robot exhibits strong dynamic coupling between the arm and the base, and the resulting position of the end of the arm depends not only on the joint angles but also on the state of the base.

Virtual Stereovision Pose Measurement of Noncooperative Space Targets for a Dual-Arm Space Robot

IEEE Transactions on Instrumentation and Measurement, 2020
Noncooperative target pose (position and attitude) measurement is very important for on-orbital servicing tasks, such as malfunctioned spacecraft capturing and repairing, space debris removal, and so on. Traditional stereovision-based methods require the

The dual space

1995
Linear functionals and the dual space of a vector space are defined and characterized. Every vector space is shown to be canonically embeddable in its second dual. Maximal subspaces are characterized as kernels of nontrivial linear functionals. The trace of a square matrix is studied in detail. Over a field of characteristic 0, a square matrix is shown
