From: Milli-scale cellular robots that can reconfigure morphologies and behaviors simultaneously

a Assembly of bastinade-shaped mCEBOT by end-by-end connection and corresponding separation by removing magnetic field. b Assembly of biped mCEBOT by side-by-side connection and corresponding separation by removing magnetic field. c Protean morphologies achieved by introducing units’ number and combining two connection methods. d Multiple configurations of mCEBOT’s morphologies by controllable assembly and separation. e The construction of single mCEBOT in a large number of robotic units. f The construction of multiple mCEBOTs at the same time in a large number of robotic units.
