A Japanese tech firm is attempting to improve wheelchairs by changing how they travel and how well they can do it. Nano-Optonics Energy’s newly released Unimo electrically controlled chair uses thin, tank-like treads to traverse the ground, which the company claims allows it to travel smoothly over difficult terrain such as gravel and sand that traditional models can’t easily handle. The chair can also climb up and down 6-inch stairs, nearly twice as high as what the manufacturer says most wheelchairs are capable of, and it can approach speeds of 4 mph.
