[@controlit2021] is a middleware built around the whole-body operational space control algorithm first introduced by Sentis and Khatib [@Sentis2006]. In contrast to the existing libraries, ARC-OPT implements unified interfaces for different WBC problems on velocity, acceleration and torque level, as well as options to benchmark different QP solvers and rigid body dynamics libraries on these problems. Furthermore, it provides a novel WBC approach for robots with parallel kinematic loops, which is described [@Mronga2022].
