DIY robots are nothing new. 3D printing parts is also nothing new. The combination of the two is also not unheard of. And yet even simple yet substantially functional robots are still in short supply today, despite advancements in the understanding of robotics or the accessibility of manufacturing methods. The problem is that event trivial robots need to be assembled, and that in itself is already quite an undertaking. MIT researchers, however, may have come upon an alternative: 3D printing a complete robot as a whole, no assembly required.
