Modeling and Balance Control of Supernumerary Robotic Limb for Overhead Tasks

نویسندگان

چکیده

Overhead manipulation tasks often require collaborations between two operators, which becomes challenging in confined spaces such as a compartment. Supernumerary Robotic Limb (SuperLimb), promising wearable robotic solution, can provide assistance terms of broader workspace, wider functionalities and safer working conditions. However, the safety concerns human-centered SuperLimb interaction mechanisms are rarely studied to date, particularly regarding human standing balance. This study proposes balance controller by one individual operator accomplish overhead with via tunable force supporting regulation. The SuperLimb-human is modeled dynamics control method based on QR decomposition (also known factorization, matrix factorized into an orthogonal upper triangular matrix) adopted decouple joint torques forces. Therefore, forces be regulated independently guarantee operator-SuperLimb safe region. Force plate used for measuring CoP position evaluation critical horizontal push learned through experiment guide controller. implemented prototype worn operator's back, necessary object while allowing move freely underneath.

Empirical modeling and comparison of robotic tasks

How can we describe and measure real robotic sys-tems? Implemented robotic systems for intelligent tasks are are often extremely complicated, depending not only onìnteresting' theoretical parameters and models, but on many assumptions and constants which may be set almost arbitrarily. In order to evaluate and compare systems which employ diverse components and methods, we are obliged to employ ...

Petri Nets for Modeling and Coordination of Robotic Tasks

Petri nets have been widely used to model dynamic systems, namely manufacturing systems. In this paper we introduce the use of Petri nets to model robotic tasks. Diierent views of the robotic task model can be modeled by distinct Petri net types: interpreted Petri nets for task design and execution, generalized stochastic Petri nets for task quantitative performance evaluation and ordinary Petr...
