I want to test the trapezoidal trajectory planner recently implemented (Trapezoidal Trajectory Planner )
That would basically let me drop my own trajectory planner in python that basicaly forced to use a big PC instead of a small raspberry pi to feed the position commands fast enough on the USB link.
I love the testing jig that you guys used to test/stress the software here => https://youtu.be/8ZAALZAqtTo
It would also be super usefull as a “smoke test” to check some parameters or algorithm even before a given machine/solution has been designed.
I want to use on of those fitness weights I still have somewhere in my garage as an inertia constraint. (something that looks like this https://www.amazon.com/dp/B01CQLGB3A/ref=psdc_3408401_t1_B0041G3ZK6)
However, i’m concerned that making a PLA/ABS printed adapter could potentially makes the table vibrate a lot as RPM increases. indeed most likely the center of gravity may not be exactly at the center or rotation. And i’m basically a bit scared to create an accident having something that heavy spinning a bit fast in case something detaches… the resulting collision could easily create significant injury.
Except for good old common sense (dont spin too fast & stay away), would you have an advice about how to make it right while still mechanically torturing the system for validation purposes? (i have no lathe :/)
