Cover Story: This paper presents a novel design for humanoid arm mechanisms, with a tripod parallel architecture actuated by linear motors. The design is validated with experimental tests on a prototype to characterize its performance and check its feasibility for implementation in the LARMbot humanoid robot. The design proves successful with a large, singularity-free workspace and a high payload to arm weight ratio. Furthermore, the prototype can be assembled with low-cost commercial components while still maintaining good motion and force performance for the successful integration with the LARMbot design.
