**3. Future**

The elderly population is growing year-by-year, and therefore, assistive robotics could help to improve their standard of living and quality of life. Additionally, it can also go beyond this group of people and help others that also currently live with disabilities and impairments. Machine learning techniques will help in developing robust methods in this area, creating products (robots, devices, etc.) and solutions that live together with humans on a daily basis.
