This thread will be used to present the drawings (both fusion and laser-ready DXF files) for the five parts of the chassis.
As the choice and location of the sensors you choose is one of the “free variables” the drawings will not include any openings for sensors etc. Be reminded that everything you use/attach must be within the footprint of the bot itself, with the exception that you can place something on top - as long as it does not fundamentally alter the design. ( e.g. a rotating scanner of some kind mounted on a micro servo would be OK to fit on top).
- Spec and order link provided for wheels
- Spec and order link provided for Servos and trimpots
While links may be provided, feel free to buy your parts anywhere (noting that common, low cost hardware is part of the competition spec). Provision of a link does not infer any endorsement of that supplier, it just means that I got it from there.
There might be an update to the drawings for the chassis to accommodate the revised wheels - I’ll make any necessary changes and post the drawings once final (also DXF files that are Sophia-ready )
