Wow, the updates to the graphical moteus monitoring application tview just won’t stop! We’ve had a lot of changes recently (python console, fault text decoding, fault monitoring, UUID addressing) and now here is yet another long requested big quality of life improvement – recording data to log files! As of pypi moteus-gui version X, tview now can write log files in either the .jsonl format as a single file or as a set of CSV files. Continue reading for more details!
Following a brief period with no stock, we’ve restocked the original 32mm x 22mm x 4mm diametric ring magnet at mjbots.com. Additionally, there are now 4 new sizes to choose from:
This should hopefully let you use low cost (albeit low accuracy), off axis diametric ring magnets in even more applications. Good luck!
Way back in 2020, I wrote about the motor saturation model that moteus uses to accurately calculate torque when a motor is operating in a region where the stator becomes saturated. What I didn’t write about was a method for actually determining those fit parameters for a given motor. This isn’t too critical, as most position mode applications don’t require the applied torque to be terribly accurate, but in some cases it does matter. When that is the case, there is now a tool that can calculate parameters appropriate for entering into moteus. Read on to find out more!
