Skill For Controlling Waveshare Serial Servos Type ST Series
These servos are high quality and the type ST3215 is also quite inexpensive. The type ST3025 (BL / metal housing) is suitable for semi-professional use. Robots for show cases and longer operating times could be equipped with this. The servos can already be activated with the Feetech RS RS485 skill. The two communication protocols are probably very similar. However, no positions feedback can be read back. I think this can be achieved with an appropriate modification of the exisiting Feetech skill. This makes it a Feetech / Waveshare skill. Certainly very useful with probably little effort
Do not use the ezb. Use the USB controller. If you use the EZB, you're introducing extra points of failure.
You also have to ensure the baud rate is correct.
... this is probably a stupid question, but how can you select a USB port in the Dynamixel skill?
It looks completely different in the Feetech skill.
Sorry and thank you very much
Ah, oh boy - that's because it's missing! We'll have to add that
Also - does your servo work with the Feetech bus servo skill? or only the rs485 skill?
No, I have now tested all servo skills.
The servos can only be controlled with Feetech rs485 skill.
There are some reports online that indicate that Feetech and Waveshare should actually be identical?
It is indeed the case, that there are some servos whose name and specification are the same for Waveshare and Feetech. This includes the ones I use. That gives me hope.
I have now also ordered a few Feetech servos. I can then test whether they provide position feedback and can also be used in multi-loop mode.
A quick update on Smart Servos, Feetech, WaveShare, multiple use of servo skills, and reading servo positions. The servos use the same protocol, but the transmission runs at different baud rates. I adjusted this outside of ARC via virtual COMs.
Acceleration and deceleration profiles are also roughly adjustable. However, reading the current servo position doesn't work yet.
Have fun watching
