Roberto Bolli, a PhD student in mechanical engineering from MIT, is on a mission to revolutionize elder care with his innovative robot, E-Bar. This robotic marvel autonomously glides behind seniors, ready to catch them if they stumble, inflating airbags in a flash. The conversation dives into how E-Bar can enhance safety and independence for older adults, making aging in place more feasible while complementing human caregivers. Roberto also shares insights from user testing, emphasizing the balance between technological assistance and human touch.
