An electromechanical joint provides rotational movement in at least two dimensions while conducting electrical power between orthogonal hubs. The joint, shaped as a cross, has four conical shafts positioned orthogonally and apart from each other within an interior of a housing. Apexes of the conical shafts face each other proximate a centroid of the housing. A conductive fluid, such as Galinstan, fills recesses between the conical shafts. Separate yokes attached to pairs of the hubs may impart forces on the shafts, causing the shafts to rotate within the conductive fluid around orthogonal axes. The conductive fluid provides simultaneous conduction of electrical power between the hubs. The yokes may be affixed respectively to a current collector and conductive arms of a work machine for improved movement and power conduction without the need for additional components.
