OpenSim gets high marks as a multibody system simulator
A recent study by Luca Tagliapietra and his University of Padua colleagues demonstrates that the OpenSim software (http://opensim.stanford.edu), which uses Simbody as its multibody dynamics engine, generates highly accurate simulations of mechanical systems. OpenSim was evaluated using the Multi-Body System (MBS) Benchmark, which consists of five systems ranging from a simple pendulum to an over-constrained system of five rods and six rotational joints (Bricard’s mechanism). This work (extended abstract: http://www.multibody2015.org/admin/files/fileabstract/a13.pdf) was presented at the 2015 European Congress on Computational Methods in Applied Sciences and Engineering (ECCOMAS) Thematic Conference on Multibody Dynamics (see page 1572 of the Proceedings). You can learn more and download the code that implements the benchmarks in OpenSim at https://simtk.org/home/mbs_bos.
Simbody source moved to GitHub
To facilitate a more social style of shared code development, Simbody's source code is now being maintained on GitHub, at https://github.com/simbody.
Simbody joins the DARPA Robotics Challenge
DARPA granted a sole-source contract to the Open Source Robotics Foundation (http://osrfoundation.org) to build a shared simulator (Gazebo) for the DARPA Robotics Challenge. OSRF awarded a research subcontract to Stanford Bioengineering to incorporate Simbody as a high-accuracy physics module in Gazebo, and to develop a novel approach to high-speed, physically-accurate contact modeling suitable for use in real time robotics simulations. Prof. Scott Delp is the Principal Investigator; Simbody principal developer Michael Sherman and postdoc Tom Uchida will participate. The 2.5 year subcontract began in October, 2012.
