Unfortunately, the standard electrode-over-skin method of control makes many of them unreliable and restricts their functionality, meaning that a number of recipients of these devices commonly reject them as a result. However, a Swedish man has recently celebrated a milestone in robotic prostheses by taking advantage of an osseointegrated (bone-anchored), thought-controlled, implant system in his daily life for more than a year and a half.
Gizmag previously reported on the initial pre-operative technology being developed for this operation by researchers at Sweden's Chalmers University of Technology, where the prosthesis was developed. At the time, the team had hoped that the sophisticated algorithms within the artificial arm would give the subject finer control over movements than electrode-over-skin control had demonstrated. Given the efficacy claimed by the researchers in subsequent testing, this hope seems to have come to fruition.
