Automatic ergonomics whole-body motion analysis and physical human-robot interaction
Some work activities in industry are commonly executed by workers in a non-ergonomic fashion, which may lead to musculoskeletal disorders in the short or in the long term. WMSDs are known to be caused by multiple factors, such as repetitive motion, excessive force, and awkward, non-ergonomic body postures. Not surprisingly, work environments with such factors may present an incidence of WMSDs of up to 3 or 4 times higher than in the overall population.
In this talk, we show our approach to evaluate the human motion with respect to ergonomics indexes, optimize the motion, and intervene on the task based on the optimized motion.
In the first part of the talk, we show how digital human models can be used to evaluate body posture according to classic ergonomics indexes and/or joint torque estimations. We show how this approach can be extended to evaluate the impact of external agents, such as robots and exoskeletons, that may be in physical contact with a human. In particular, we show the results of a pilot study that evaluated the impact of commercial exoskeletons (Laevo, Corfor, CrayX, BackX) for a typical strenuous activity in the health sector.
In the second part, we propose an approach to improve initial whole-body motions according to one or multiple ergonomics indexes using single- and/or multi-objective optimization. Then, we make the case that a robot could use physical interactions to drive the human towards more ergonomic whole-body motions, possibly to an ergonomically optimal motion.
In the last part, we briefly talk about the importance of studying human motor behavior during physical interaction to improve current human-robot collaboration strategies. This is illustrated by preliminary studies on a co-manipulation task executed by a human-human and a human-robot dyad.

Terrabyte Co. Ltd. acquires 60% of AnyBody Technology
Terrabyte Co., Ltd. with headquarters in Tokyo, Japan, has acquired 60% of the Danish company AnyBody Technology A/S and has thereby become the largest shareholder of AnyBody Technology A/S. The acquisition has been performed in two stages over the last 1½ years with decisive effect from June 2021.
AnyBody Technology and Terrabyte are already close partners and have over the past 6 years delivered a large number of projects with Terrabyte as the operation partner and AnyBody Technology as the software application provider. Now the parties have joined forces and will continue to develop the cooperation and business globally.
“We see AnyBody Technology as a solid and strong company with a unique state of the art technology that has evolved and developed over the past 20 years. AnyBody Technology possesses a worldwide marked leading position with its validated simulation software. The founders and the management team are very strong profiles, and they will continue the overall management of AnyBody Technology”, says Tadashi Komori, CEO, Terrabyte.
We have high hopes for the continued development of AnyBody Technology together with Terrabyte. The partnership with Terrabyte has been well established over the past 6 years and we have delivered numerous projects together in the Asian region. We are looking forward to reinforcing and strengthening the partnership with Terrabyte and to developing our company even further on the global market”, says Jørgen Rosenkilde, CEO, AnyBody Technology.
AnyBody Technology will continue with the existing management team and will proceed to operate as a separate company, focusing on delivering high-end biomechanical simulation software and offering services directly to customers and clients. All the while, Terrabyte will support the future business development and growth of AnyBody Technology.
Is a bio-engineering company with headquarters in Aalborg, Denmark which spun off from Aalborg University and was founded in 2002. AnyBody Technology develops musculoskeletal models and bioengineering software based on cutting-edge biomechanical research. The software is used by research and commercial customers globally, but most extensively in Europe, Asia, and North America.
Terrabyte Co., Ltd.
Is a CAE software engineering company founded in 1997. It has since 2014 been the prime distributor of AnyBody Technology software in Asia. In addition to technical consultation for non-linear structural analysis software LS-DYNA and open-source thermo-fluid software OpenFOAM, Terrabyte also provides sales support for various CAE software and services for measuring material physical properties and human body movements. Terrabyte operates the Asian market from the HQ in Tokyo and from Shanghai, China.
