It　is　a　challenging　task　to　carry　on　the　research　concerning　the　lateral　stabilization　of　Single　wheel　robot　(SWR).　The　lateral　dynamics　of　earlier　flywheel　stabilizing　SWR　is　derived　to　explain　the　shortcomings　of　such　a　mechanism,　and　the　recovery　torque　proportional　to　the　acceleration　and　moment　of　inertia　of　the　flywheel　is　proved.　But　as　the　motor　being　a　speed　server　system,　it　is　difficult　to　control　its　acceleration　to　actuate　the　flywheel　to　provide　recovery　torque　for　SWR;　and　the　moment　of　inertia　of　the　flywheel　must　be　large　enough　to　produce　adequate　recovery　torque,　which　makes　such　a　system　rather　cumbersome.　We　proposed　a　new　mechanism　to　solve　the　problem　by　introducing　an　electromagnetic　force.　The　proposed　mechanism　is　described　briefly,　and　the　dynamic　analyses　of　such　a　new　SWR　is　given,　then　the　stability　analysis　is　also　done.　Three-dimensional　(3D)　multi-body　simulation,　numerical　simulation　and　physical　invented　pendulum　prototype　experiments　were　conducted　to　verify　the　proposed　mechanism.　The　experiment　results　verified　that　the　proposed　mechanism　is　feasible　and　have　some　advantages　over　the　flywheel　balanced　SWR.
