TEAM: a parameter-free algorithm to teach collaborative robots motions from user demonstrations
Lorenzo Panchetti, Jianhao Zheng, Mohamed Bouri +1
Learning from demonstrations (LfD) enables humans to easily teach collaborative robots (cobots) new motions that can be generalized to new task configurations without retraining. H…
The Robotic Multi-Object Focal Plane System of the Dark Energy Spectroscopic Instrument (DESI)
Joseph Harry Silber, Parker Fagrelius, Kevin Fanning +97
A system of 5,020 robotic fiber positioners was installed in 2019 on the Mayall Telescope, at Kitt Peak National Observatory. The robots automatically re-target their optical fiber…
Experimental evaluation of complete safe coordination of astrobots for Sloan Digital Sky Survey V
Matin Macktoobian, Ricardo Araújo, Loïc Grossen +4
The data throughput of massive spectroscopic surveys in the course of each observation is directly coordinated with the number of optical fibers which reach their target. In this p…
SDSS-V Algorithms: Fast, Collision-Free Trajectory Planning for Heavily Overlapping Robotic Fiber Positioners
Conor Sayres, José R. Sánchez-Gallego, Michael R. Blanton +8
Robotic fiber positioner (RFP) arrays are becoming heavily adopted in wide field massively multiplexed spectroscopic survey instruments. RFP arrays decrease nightly operational ove…
Four-Arm Manipulation via Feet Interfaces
Jacob Hernandez Sanchez, Walid Amanhoud, Anaïs Haget +3
We seek to augment human manipulation by enabling humans to control two robotic arms in addition to their natural arms using their feet. Thereby, the hands are free to perform task…
Cable-driven robotic interface for lower limb neuromechanics identification
Hsien-Yung Huang, Ildar Farkhatdinov, Arash Arami +2
This paper presents a versatile cable-driven robotic interface to investigate the single-joint joint neuromechanics of the hip, knee and ankle. This endpoint-based interface offers…
An 8-mm diameter Fiber Robot Positioner for Massive Spectroscopy Surveys
N. Fahim, F. Prada, J. P. Kneib +22
Massive spectroscopic survey are becoming trendy in astrophysics and cosmology, as they can address new fundamental knowledge such as Galactic Archaeology and probe the nature of t…
Collision-free motion planning for fiber positioner robots: discretization of velocity profiles
Laleh Makarem, Jean-Paul Kneib, Denis Gillet +6
The next generation of large-scale spectroscopic survey experiments such as DESI, will use thousands of fiber positioner robots packed on a focal plate. In order to maximize the ob…
Developing Micro DC-Brushless Motor Driver and Position Control for Fiber Positioners
Laurent Jenni, Philipp Hörler, Laleh Makarem +7
In the large-scale, Dark Energy Spectroscopic Instrument (DESI), thousands of fiber positioners will be used. Those are robotic positioners, with two axis, and having the size of a…
Collision Avoidance in Next-generation Fiber Positioner Robotic System for Large Survey Spectrograph
Laleh Makarem, Jean-Paul Kneib, Denis Gillet +5
Some of the next generation massive spectroscopic survey projects, such as DESI and PFS, plan to use thousands of fiber positioner robots packed at a focal plane to quickly move in…
