OTO v2 is a compact whiteboard-cleaning hardware project and FDM mechanism testbed.
Improving on OTO, a senior capstone automated whiteboard cleaner built around printed parts, Arduino control, and rack-and-pinion motion, OTO v2 is being developed with three things in mind: faster, cheaper, and sleeker.
It is being used to explore how far printed parts can go when the mechanism, material, service behavior, and manufacturing method are designed together from the start.
The original OTO repo includes STL files, Arduino motor-control code, a capstone report, and media from the first working direction.
OTO v2 uses that work as the starting point, not as a fixed architecture. The goal is to keep the useful lessons from the original build while revisiting the mechanism, printed part strategy, pad service, packaging, and cost from a cleaner baseline.
See docs/original-oto.md for the short reference summary.
- printed mechanism design
- rail and chassis geometry
- pad interface behavior
- fastener boss design
- serviceability
- FDM prototype constraints
- measured behavior from physical iterations
Early prototype / active development.
The repo will start with documentation and design notes, then expand as files are cleaned up for public release.
Some projects are easiest to understand only after they move through real hardware.
OTO v2 is a place to document that process: the rough prototypes, the decisions, the failures, and the design changes that make the next version better.
