Newer devices are currently being marketed to the blind community, but today, most people still rely on a long cane or guide dog to get around. Its similar to the way we learn to differentiate, through echoes and vibrations, the sounds of a booming cathedral and a tiny closet. pain. In the decades since Griffins early work, we have discovered that bats approaches to echolocation are incredibly diverse. "We're going after this disruptive opportunity," says Winter, an assistant professor of mechanical engineering at MIT. Due to the properties of a fluid-filled cylinder, the amputee is able to increase and decrease walking cadence with the knee automatically compensating.
