Abstract: The lattice selfreconfigurable modular robot has attracted more and more attention for its excellent flexibility in connection and separation movements. A novel selfreconfigurable robot module, called MLattice, was presented. A genderless pinslotbased connection mechanism was introduced. The static and dynamic experiments indicate that the selfreconfiguration connection can be accomplished by the mechanism smoothly and rapidly. The time cost of the connecting movement is approximately 2 seconds and the strength of connection between the two mechanisms is capable of over 50 N axial load.
