comment What are the biggest one piece wheel?
Confirmed, though it is missing a center hub and is thus difficult to use. The next in size that does have one is 59521 bricklink.com/catalogItem.asp?P=59521

comment How can a Mindstorms robot lift something very heavy?
Proper down gearing (and strong structures) can indeed make wonders... See this tiny LEGO RCX robot lifting and moving a 44kg load: philohome.com/hoist/hoist.htm

Problem is that I am not Python savvy... Might be a physical interface problem too?

The duty cycle percentage is the ratio between powered time over cycle period. Eg. here, a 30% duty cycle at 1200 Hz means 250µs on / 583µs off.

For the large linear actuator you can also used this specialized part (bricklink.com/catalogItem.asp?P=61905) but unfortunately it's rare and expensive

For the record, this part is also one of the two glued halves forming the old pin joiner (brickset.com/parts/design-75535). Its LEGO reference is 6221 (brickset.com/parts/design-6221)

comment How to unplug black friction pin connectors
My preferred method is the last one, but instead of using a Technic brick, I use a half width beam. The stick blocks the pin as it does with the full width brick, but once the stick is removed, the pin is very easy to pull out from the beam.
