This is the accompanying report and documentation for the rotocasting machine, made in 2025 for the KU Leuven soft robotics research team.
Software
Here, you can find the main code under RotocasterMainFirmware (arduino .ino files) as well as other people's libraries used for this project.
I changed some of these libraries to add or change functionalities, so be sure to add the ones you find here to your Arduino -> libraries directory
You should also have the Earle Philhowers Arduino Pico core installed.
Some useful tutorials for uploading:
https://randomnerdtutorials.com/programming-raspberry-pi-pico-w-arduino-ide/
Electrical Hardware
The KiCAD design files can be found here. If there is something that needs to change, you can find the current version of the project here. The small problems with the current version are already implemented.
Mechanical Hardware
A .step file is uploaded here to get a better grasp of what might be going on under the covers. This is not a build guide, rather part of the documentation. Same thing for the bill of materials, where you can find all the parts used in this project

Questions
How big is the LocalRoboCaster PCB?
It measures 100 × 83 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LocalRoboCaster use?
72 parts, built around the IRLZ44NPBF and IRL3705NPBF. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the LocalRoboCaster KiCad files?
From the JarneVG/RotocasterKUL repository on GitHub, at the commit this page was made from: the board is Electrical hardware/Electrical Design/LocalRoboCaster/LocalRoboCaster.kicad_pcb and its schematic Electrical hardware/Electrical Design/LocalRoboCaster/DataInAndOut.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LocalRoboCaster design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
