A 3D-printable robotic arm concept combining mechanical design and Arduino Nano–based electronics, with an overall budget target of less than €50.
Rotate and zoom the actual geometry provided for this project. You can also isolate the seven export groups from the OBJ file. These groups have not yet been identified as separate moving parts.
The project explores whether a robotic arm can be developed with 3D-printable components and a relatively inexpensive microcontroller. Keeping the total cost below €50 is a design constraint rather than a documented result.
The mechanical layout is being refined alongside the first printed parts. Actuator selection and movement performance will be documented once they have been tested.
The electronics are planned around Arduino Nano. Circuit design, control software and system testing remain part of the ongoing development.
A number of components have already been printed and the physical assembly has begun. The complete system is not finished.
A real 3D model is available in OBJ and STL formats. The browser viewer uses the supplied OBJ geometry.
Physical prototyping is underway: some components have been printed and assembly has started. The current build is still partial.
Electronic integration, component costs and functional testing are still to be documented.
Future case studies can combine models, detail photographs, short videos and concise engineering notes. Each project should explain what was designed, what was actually built, and what was tested.
