Remember the Myo Armband? We have covered many Myo projects here in the past. It can be used to control smart devices, robots, and even prosthetic limbs. As the below video shows, Johns Hopkins University researchers have developed a new surgical technique that allows an amputee to control a modular prosthetic arm with two Myo armbands.
This MPL relies on Myo units to pick up muscle activation signals in the upper arm. It can make life easier for a lot of people. More information is available here.
