The collision gate was designed to allow for the colliding LMs to have a free path post-collision. This enabled the monitoring of the LM paths, and the future design and implementation of exiting pathways, creating a logic gate. Two 16.0 cm acrylic pathways were slanted towards each other at 20 • , affixed to an acrylic base sheet (3.0 mm thick). The acrylic base sheet was then aligned with a pitch of 38 • from horizontal, giving a final LM pathway slope of 16 • from the horizontal plane. This gave reliable LM rolling without extreme angles. The gap between the two slanted pathways was set at 1.6 cm, after empirical testing. A 2.0 cm, length at the top of each pathway was made hydrophobic, as discussed above. Parallel autoformation of hybrid LMs was achieved using the syringe driver, delivering 11.6 µl of water per syringe per drop. Each droplet of water was permitted to land on the treated section of each slope, before rolling across the powder beds of UHDPE and Ni to form LMs. The two rolling LMs were then captured using the electromagnets, allowing for any slight timing deviations to be accounted for. On controlled synchronous (or asynchronous) release of the electromagnets, the LMs simultaneously roll off the acrylic ramps on collision trajectories. Collisions were recorded at 120 fps using a Nikon Coolpix P900, and played back frame-byframe for analysis.
