Aiming　at　the　elderly　and　the　physically　disabled,　this　paper　designs　a　novel　Intelligent　Wheelchair　Bed(IWB)　to　solve　the　physical　problems　(moving/living/etc.)　in　their　daily　life.　Firstly,　the　proposal　of　IWB　is　presented　by　comparing　similar　existing　technologies　and　products　based　on　current　application　status.　Focusing　on　creative　features　of　IWB,　this　paper　analyzes　some　design　issues　of　main　functional　modules　(deformation　mechanism,　suspension　and　omni-direction-wheel　mechanism,　and　safety　system,　etc.).　Some　key　algorithms　are　also　discussed　such　as　interaction　control　between　human　and　machine,　autonomous　docking　and　motion　compensation.　In　the　later　part　of　this　paper,　implementation　and　tests　of　the　prototype　are　demonstrated.　By　these　efforts,　the　authors　believe　that　technologies　packaged　in　IWB　will　form　a　new　useful　robotic　product　and　make　contributions　to　the　upcoming　aging　society.　©　2018　IEEE.
