Re: federated free software movement

[Arthur Torrey <arthur_torrey@comcast.net>]

We seem to keep going round and round on this one...

The original post on the topic was about a possible 'federated Free software movement' to include (among others) Free Software advocates, the right to repair folks and the open hardware community.  Each of these groups has their own lists, websites, and other methods of communicating within their own circles, and sets their own expectations of what is and isn't OK within them....

I would expect any federated activity to be in SEPARATE lists, websites, etc. that are NOT part of the 'internal circles' of any of the groups, but are rather an intersection of them.

What I am trying to say is that in those separate "federation" cooperative groups there needs to be a focus on the shared objective and willingness to accept that participants from other circles may not have all the same feelings about issues that are only tangentially related...

Think of it as something like the various ecumenical religious associations that are intended to allow persons of differing faiths to work together towards common goals without fighting about details of doctrine...

I never intended that we should promote non-free software / hardware on this Libre-planet list, only that we should be tolerant about it on whatever federation structures evolve.

In terms of the power chair, the hardware outside of the electronics is pretty universal, in fact there are only a few companies that make much of it.  The actual chair 'manufacturers' only really make the frames and a few other bits that they then attach outsourced parts to....  So basically you end up with two motors (almost always brushed DC gearmotors) for the main drive system, and optionally, one or more linear actuators for various seating functions.  The electronics typically consist of a pair of high current PWM  motor controllers that handle the tank-steer mixing of the drive motors, one or tw input module(s), usually just one, and a module to control any lights, actuators and other auxiliary functions.  There may also be extra added functions for things like Bluetooth input to a computer / phone, environmental controls and so on, mostly only seen on very complex chairs for those with extreme disabilities.

All the modules on a given chair must come from the same manufacturer and model family.  They will be linked together using proprietary cables, and communicate using proprietary protocols, so it is not possible to just reverse engineer one of them, you have to do the entire system.  There is also a lot of fail-safe / safe-fail engineering required to ensure that everything works properly.  

It is a seriously gnarly problem
