The robots were printed to stand vertically over the pillar connected to the substrates. a We show an array of robots standing perpendicularly to the substrate, b a top and tilted view with an angle of 45 degrees of a standing robot, and c a top-view of a robot detached from the substrate to show clearly the printing of the different components of the OPTOBOT; the helix, optical handles, and the indentation at the front optical handle.
