Research and Development in Self-Replicating Open-Source 3D Printing
This is a project to create a neuromorphic analogue neural network. I wanted to get away from using conventional computers (including parallel graphics processors) to do neural simulations and instead to make something that is a lot more like a
We are in the process of doing major veterinary surgery on our Petoi Robot Dog to add organs to it, namely LIDAR rangefinding, a camera, foot sensors so it knows when it’s stepped in something, and recharging when it seeks
The other day I started a brief Twitter discussion by saying something that I thought to be true: “…SLA can’t do multiple materials in a single print.” But, as Bill Steele and Joel Telling pointed out, I was wrong. Also
We have been experimenting with 3D printed Ravigneaux epicyclic gears to get a high-reduction-ratio gearbox in a compact space for making robots. They work if you drive them with a high-torque from an already geared-down motor, but they suffer from
A while ago Naomi Wu 机械妖姬 very kindly sent us one of Creality‘s infinite-Z belt printers. Lots of people have printed long I beams on this type of machine, but we thought that we’d write a Python FreeCAD program to
For an introduction, all the documentation on this project, and to read what we did up to this point see our Github repository here. After a year-and-a-half gap (caused, inter alia, by the Covid pandemic) we have come back to
This is a project to create a painting robot. But this is a tricky thing to do, so we will do it in stages hoping that each stage on its own will be useful. Background A while ago any half-decent
In our previous blog post on this topic we finished with a joystick design that had two degrees of freedom: rotation about the X and Y axes. We have now added rotation about Z to that to create a device
A Project to create open-source 3D printed 6 DoF input devices Following a discussion on Twitter the general consensus was that a 3D-printed open-source spacemouse that anyone could make would be a good idea. These are used for input to
This post is about the work in progress on our design of an open-source 3D-printed brushless DC (BLDC) electric motor. These have the advantages of high torque, precise speed control, and no moving electrically connected parts. This is an ongoing
