[Accepted] 3rd Ergonomic Human-Robot Collaboration: Opportunities and Challenges
In many industrial countries, work-related musculoskeletal disorders (WMSD) are associated with high costs to employers such as lost productivity, worker's compensation costs, and so on. WMSD risk factors include awkward posture, repetition, mechanical compression, vibration, etc. To tackle such risk factor, a workplace ergonomics assessment comprises of intervention descriptions for WMSD and the intervention strategy for reducing, eliminating, or controlling worker exposure to the WMDS risk factor. These measures aim to ensure workers' health and safety. Human-Robot Collaboration (HRC) a promising concept that can potentially help with maintaining and improving ergonomics and working conditions of human co-workers. However, the traditional HRC technologies mostly focus safety in terms of collision avoidance and impact safety, while ergonomics potential is largely under-exploited. Therefore some of the major challenges and opportunities to exploit such potential are: collaborative robots have to be aware of co-worker's state and predict his/her actions; the interactive motion has to be able to reconfigure the human working conditions; the methods must operate online.
The above-mentioned challenges and opportunities present a novel research topic for the community. We previously organized two successful workshops to establish the field and to discuss this topic. First, we held a workshop at ICRA 2018 to introduce and discuss the concept in terms of collaborative robotics. Then we held a continuation workshop at IROS 2019 to review the initial research progress based on the goals set at the first workshop and identify major ongoing research problems. Now it is time to discuss those problems and come up with solutions to make progress towards robust and applicable methods for ergonomic human-robot collaboration.
The proposed workshop will first review the progress of the research and development in the new field that was achieved since the last workshop at IROS 2019. Next, we will focus on how to solve the problems that emerged during the research and development based on the goals that were set at the previous workshop. In addition, we will discuss potential novel research directions, ergonomic metric and robot control methods. Finally, we will discuss and design new validation methods that can be used for objective benchmarking within the field. Such an approach requires experts from various research fields and interdisciplinary discussion. For this purpose, we assemble a diverse set of organizers and speakers, who are leading experts in their respective areas that are highly relevant to this workshop topic.
The questions we want to address
How to clearly define the measures for ergonomics in human-robot collaboration?
- How to design the appropriate optimization that the robot controller can use?
- Are the proposed ergonomic measures sufficient to ensure ergonomic conditions and prevent work-related injuries in terms of bio-medical aspects?
- How to improve the existing modelling of the human and effectively apply it to achieve ergonomic human-robot collaboration?
- Learning algorithms may help the robot to overcome some of the above-mentioned issues.
- What kind of additional sensory feedback systems are required?
- How can robot learning methods be utilized to this end? What are the challenges in achieving the proposed goal in different applications (i.e. industrial human-robot collaboration, wearable robots, service robots, etc.)?

"Prediction and optimization for ergonomics movement in human-robot collaboration"
In this talk I will present our recent results in prediction of human movement for improving human-robot collaboration and optimization of human movement with respect to ergonomics criteria.
"Improving workers’ ergonomics by cobots and exoskeletons"
Cobots allow to combine the dexterity, flexibility and problem-solving ability of humans, with the strength, endurance, quality consistency and precision of robots and can be redeployed to other tasks much more easily. By also placing health, the working conditions and the sustainable development goals central, we can ensure ourselves to reap the full benefits not only economically but also for our society. This talk will discuss the multidisciplinary approach to develop a new generation of cobots and exoskeletons and control algorithms for improving the ergonomics of workers in the manufacturing industry.

"Effects of a whole-body, powered exoskeleton on the completion of industrial tasks: current metrics and future adaptations"
Despite advances in industry automation and mechanization, the flexibility, dexterity and resourcefulness of humans are indispensable in diverse work environments. In these environments, workers are often routinely exposed to ergonomic risk factors for work-related musculoskeletal disorders (WMSDs), the single largest component of work-related illnesses in many industrialized countries. There is a growing interest in using wearable robotic devices such as “whole-body” powered exoskeletons (WB-PEXOs) to prevent WMSDs. Using an exoskeleton provides on-body assistance/augmentation to the wearer, thereby potentially reducing physical demands without limiting their mobility and resourcefulness in various work environments. Exoskeletons thus allow for effective and flexible integration of manual and automated operations by augmenting the physical capacity of workers (e.g., strength, endurance) while minimizing exposure to WMSD risks. Currently, however, there is a lack of understanding exactly how human operators learn, use, and adapt to such technologies. Previous exoskeleton research is largely limited to passive exoskeletons that require no power sources or actuators/motors, so there is practically no scientific literature available on human-subjects evaluations with WBPEXOs that can quantify the ergonomic impact on human operators. Understanding these effects is crucial to developing a robot that can closely interact with a human in a work environment.
We conducted a study in which we assessed how using a prototype WBPEXO (early pre-alpha version of Guardian XO with 24 total degrees of freedom, 8 active, www.sarcos.com) impacts human operators in terms of body motion control, muscle activity, and task performance. Five participants were evaluated during the performance of several industry-relevant tasks, both with and without the XO. Outcome metrics derived using body kinematics and muscle activity showed the current effectiveness of XO during the different work tasks, and identified specific aspects in which it needs further development to better collaborate with the human. Our results support the potential for effective use of whole-body powered exoskeletons in the future workplace, and contribute to the evidence base regarding the use of an industrial WB-PEXO by identifying the metrics that best describe the ergonomic state of the human while operating the WB-PEXO. The findings from this study will enable the development of novel controllers for the WB-PEXO that are aware of these ergonomic metrics and are able to continuously adapt to the ergonomic state of the operator, thereby increasing the ease and safety of the industrial environment, and decreasing the risk of WMSDs.
