Tried making a 10-spoke speed encoder wheel that fits the Tamiya 4WD tires, its too brittle and uneven. My plan is to have the optical speed encoder just arch over the main wheels while they spin, instead of trying to read a separate encoder disc. I will try 5 spokes and wont bother with concave shape, I'll just have the holes flat and square. The diameter with the Tamiya wheels is 28.5mm, one revolution is 9cm, so two revolutions or 10 clicks is exactly one maze block traversed.>>969
Repost but the sumobots in action:
In the horizontal pic the bots in order of completion are 1,3,4,2,6,5.
Future bots are all waifu types, using some variation of the Fluffytail design and/or 3D doll pieces:
7. Micromouse (has its own current thread)
8. Cattymouse(larger micromouse with stepper motors)
9. Penguingirl balancebot(bluetooth control)
10. Kiwigirl balancebot(using 2.4Ghz RC radio and stepper motors)
11. Fluffy Rachnera-san(12-servo quadruped)
12. Fluffy Wresler(at least 14 metal gear servos)
13. Panzergirl waifutank (torso on tracked tank chassis)
14. Panzergirl devastator (torso on mecanum wheels). 13 and 14 will dress up like pic related.
Unfortunately neither of the future bots will stand taller than 40cm, I do not have the mechanical know-how to design for high torque, high weight applications.
I've noticed in related news, consumer home robots are closing shop: the makers of Kuri, Jibo, Cozmo, Vector. Most of the AI of those robots are in private servers so the bots will essentially die unless the AI is open-sourced.
Apparently the only successful "robots" are the Roomba, Siri, Alexa, Google Home etc. Either single-function tools or subsidized spyware. That is not good.
We must change that. Right now all I can do is work on creating a standard list of serial commands so that all my future waifubots can be controlled through a single universal arduino-compatible controller - either a physical controller that uses bluetooth or 2.4Ghz RC frequencies, or an app. Later waifus will have audio and video processing so I'm hoping I can offload that to a desktop computer.
I'm just sharing this infodump since I hope even though our paths may be plagued by a thousand PLA carcasses, there is a clear vision of what progress should look like, for me at least.
