4th Ergonomic Human-Robot Collaboration: Applications and Future Research
Friday, October 1st, 2021
We invite you to join the live sessions of IROS 2021 Workshop on “4th Ergonomic Human-Robot Collaboration: Applications and Future Research”:
* Time: 16.10 - 18.10 (UTC+2), 1st of October, 2021, Friday
* At least The WORKSHOPS & TUTORIALS registrations required.
Work-related musculoskeletal disorders (WMSD) often plague productivity of workers and negatively affect their living standards. The loss of productivity comes at the expense of competitiveness of companies and high healthcare costs associated with treatment of WMSD. These issues often arise from workers being exposed to various common risk factors during the physical work, such as improper working posture, repetitive high load, mechanical compression, vibration, etc. The experimental techniques to confront these issues are mainly based on heuristic strategies and ergonomic guidelines to work in such a way to reduce or eliminate the risk factors related to WMSD. However, these are mostly designed human workers only and often do not account for collaborative robots (cobots) or wearable assistive systems of the modern industry. Therefore, new methods have to be developed that effectively associate the ergonomics monitoring and risk elimination techniques to Human-Robot Collaboration (HRC). For example, cobots should be aware of the human worker's states and predict his/her actions and use physical or non-physical actions to improve the working conditions in an online manner.
Some methods have been recently developed, in part, thanks to a string of successful workshops on this topic that were organised by our team in the past. We organised the first workshop of this series at ICRA 2018 to introduce the field of ergonomic human-robot collaboration. We then followed up with a workshop at IROS 2019 to review the initial research progress based on the goals set at the first workshop and to identify major ongoing research problems. Finally, we continued with a workshop at IROS 2020 to discuss the emerging research opportunities and challenges. Now comes the time to discuss the potential applications and implications in real-world scenarios.
The proposed workshop will first review the progress of the research and development in ergonomic human-robot collaboration that was achieved since the last workshop at IROS 2020. In particular, we will try to reflect on whether the identified challenges were resolved and the identified opportunities were capitalised on. We will then focus on identifying the main real-world applications where the methods can be effectively applied, and discuss and devise the strategies to facilitate the identified applications. In addition, we will discuss potential novel research directions, ergonomic metric and robot control methods. This agenda requires experts from various research fields and interdisciplinary discussion. For this purpose, we assembled 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.)?
- Software for simulating, planning, and predicting a shared manufacturing workspace can be very useful to ensure correct task scheduling and agent allocation in human-robot manufacturing.
- Cognitive ergonomics-related problems (e.g., mental stress, etc.) will become more relevant in future when robots take most of the physical aspects away from humans.
- We need to strike a good tradeoff between productivity and stress. Game theory based methods can control this tradeoff.
- We need to strike a good tradeoff between involvement and stress. If we involve the human too much, it will stress him/her. If we remove him/her from the task too much, they will feel “useless” or “bored”.
- Collaborative robots should be equipped with human biomechanical models in order to optimize and adjust the collaborative task execution.
- Reconfiguring haptic devices during teleoperation can improve human operator’s working postures. In tele-impedance, commanding low remote robot impedance can improve execution of force-level tasks.
- Back pain due to improper working conditions is very common. Exoskeletons can be a very useful solution to this problem for tasks that involve heavy lifting and carrying. However, exoskeletons can take a lot of space to wear and time to equip, and can also add other negative aspects, such as increased sweating, etc.
- Workers might be reluctant to use exoskeletons, therefore a proper motivation and communication strategies are critical to promote acceptance.
- Mechanical design of exoskeleton plays an important role in ergonomics and its acceptance. Light passive exoskeletons can be a good alternative to bulky active exoskeletons.
- Field studies are crucial to accelerate the application of ergonomic human-robot collaboration and exoskeleton systems.
- We need learning algorithms that work in real-time and continuously.
- While we do our best to prevent injuries to the human musculoskeletal system, they will still happen from time to time. Therefore, we need effective robotic physiotherapy/rehabilitation systems that can sense humans and perform safe physical guidance.
- Physiotherapy/rehabilitation systems should use feedback from biomechanical models to ensure safe, fast, and more complete recoveries. However, models have to be personalized correctly to be effective.
- In some cases injuries require use of a prosthesis to replace the lost limbs and restore functions. The control of the prosthesis should use predictive machine learning systems to account for ergonomics.
The workshop will take place on Friday, 1st of October, 2021.
