I am glad to see that they are using LEGO Technic chains (https://www.bricklink.com/v2/catalog/catalogitem.page?P=3711 https://www.bricklink.com/v2/catalog/catalogitem.page?P=3711) , and therefore the gear pitches are LEGO compatible (at least with the non-bevel gears, but the traditional spur gears). I am excited about the potential of interacting with existing Technic parts!
