Cover Story: A modular deployable robot, which adopts an origami structure instead of a flexible hinge, has been proposed and is examined within this work. The forward and inverse kinematic models of the robot were established by using the screw theory. A prototype of this robot was constructed, and its folding performance and bending performance were tested. In the folding test, the folding rate reached 60.71% in an upright state and 61.75% in an inverted state. In the bending test, the robot reached a 180° bending angle in both upright and inverted states. Finally, this study also tested the motion accuracy of the robot and performed an error analysis and optimization; the optimized robot position error was reduced by about 65%, effectively improving the motion accuracy and stability of the robot.
