With unwavering basic in our thoughts, we compass adversity and emerge stronger on the other side. After a few trials and errors, we know that the distinctive feature of human-robot collaboration is the absence of physical separation between robots and humans – as they work with no safety gear in the same work fields. In addition, we know this research will show that intelligent robots will soon be ready to serve in our homes, hospitals, offices, and environments. In support of our previous paper, rehabilitation robotics has produced exciting new ideas and novel human assistive devices in the growing field of biomedical robotics. We know that these experimental results showed that the recognition accuracy was 94%, and the average delay time was 300 ms, which met the requirements in the actual rehabilitation process at this moment. Therefore, many hope among scientists, robotic enthusiasts, investors, and learners for the knowledge to get harmony with the information will be a good reference and basis for other variants and methods in our further implementation progress of bio-robotics development in these fields.
