Supernumerary 4-Handed Manipulation

Supernumerary manipulation refers to the usage of robotic/artificial arms in conjunction with one’s biological arms to perform a task.  Supernumerary robotic manipulators (SRMs) consist of one or more arms that extend the person’s workspace and the number of actuated degrees of freedom (DoFs). SRMs enable a single person to do tasks that would otherwise require a team of two. Control of SRMs is challenging, as it must be done concurrently with the control of the operator’s biological limbs. For instance, an operator may use a pair of extra arms to support a load, freeing their hands to perform finer-grained manipulation on the carried object. Acquiring expertise in controlling SRMs necessitates training, and even after achieving proficiency, utilizing SRMs imposes a significant cognitive burden that limits their sustained use over prolonged periods.
