5 major challenges of Robotics Adaptation in Healthcare

Healthcare robotics are making exciting progress and it has an incredible ability to bring physical change to the world. But it is important to carefully consider some of the key challenges inherent in healthcare robotics, particularly in terms of the safety and well-being of individuals, who may be particularly vulnerable to harm due to their disability, disorder, injury, or disease. Concerning the use of healthcare robots, stakeholders face five major challenges.

Usability

To control robots with multiple degrees of freedom, such as wearable protheses or wheelchair-mounted arms, a high level of cognitive function is required. However, some people who need such robots often have co-morbidities that can cause another exhausting process to take control. It is likely that robots that are hard to use will be abandoned.

A 2010 study reported that as many as 75 percent of robots for hand rehabilitation were never actually tested with end users, making them totally unusable and abandoned in practice. One of the main challenges is that clinicians often have low levels of technology literacy, even those in their disciplines who are well-educated and accomplished. Therefore, if they themselves find a robot unusable, their likelihood of successfully training a direct robot user or caregiver to use the robot is greatly reduced. There are several ways this issue can be addressed. One approach is to reduce the complexity of the robot by robot manufacturers. Functional simplicity in the design of therapeutic robots can result in robots that are easier for all primary stakeholders to use, control and maintain.

Acceptability

Another important barrier to healthcare robot adoption is its acceptance. They immediately call attention to their disability, disorder, or disease when people use a robot in public. Users are already faced with significant societal stigma, so often avoid using anything that advertises their differences further, even if it provides a health benefit. Expert argues that robot manufacturers should use a “design for social acceptance” approach in addition to functional accessibility that goes beyond purely functional designs that may look awkward and clunky.

Safety

In dealing with robots, safety and reliability are incredibly important. This is even more critical for users who can rely extensively on robots to help them perform physical or cognitive tasks and who may not be able to recover as easily as non-users from robot failures. A fair amount of work has been done on safe human-robot physical interaction, especially with regard to enhancing collision avoidance, passive compliance control methods, and new soft robotics advances to facilitate gentle interaction. However, little work has been done to date on safe cognitive human-robot interaction.

People with cognitive impairment and children are especially prone to deceiving robots. In the robotics community, this is an important and under-explored issue. One way to help bridge the security gap to ensure transparency in the way decisions are made by a robot and to maintain the privacy and dignity of users. Robot manufacturers should also use in-depth testing and training schemes to allow users, caregivers and clinicians to fully explore the capabilities. This can help prevent people either relying too heavily on the robot or relying too little on it, and help to foster confidence.

Functional capability

In recent years, robotics have seen incredible gains in capacity, but many demonstrations have failed beyond highly restricted situations. When designing healthcare technology, this is particularly problematic: most problems are open-ended and there is no “one-size-fits-all” solution. Each person, task and care setting is different, requiring robots to be able to robustly learn and adapt on the fly.

Real-world, real-time, robust perception in human environments is another major challenge in robotics. Computer vision has seen progress in still image resolution, fixed camera recognition issues, but these algorithms perform poorly when both cameras and people move, data is lost, sensors are occluded, or the environment is cluttered. In human social settings, these situations are highly likely, and in these settings, feeling, responding to and learning from end users is an open challenge.

Cost

They were claimed as a means of saving time for clinicians and patients when electronic health records (EHRs) were first used in hospitals. Because EHR systems were so poorly designed, hard to use, and poorly integrated into existing, however, they ended up creating much more non-value-added work. This led to “unintended consequences,” including higher costs and harm to the patient. Therefore, it is important to consider their cost-effectiveness beyond the cost of buying, maintaining, and training when robots are introduced in healthcare. The Agency for Healthcare Research and Quality (AHRQ) has created a guide to reduce unintended consequences for EHRs, and the same approach can be used for robots.
