Simulator rig with ODrive


#21

Hi,

The chanches are small but the program could fail, so I would take a NC limit switch and put it between the power cable, be sure to take a big one to not lose to much voltage

Hi,

How are you planning to connect with the Xsim software? Are you going to connect the odrives to your computer or are you going to send it to a raspberry pi for example? Do you have some more information for me about the Xsim software because I havn’t figured that out jet.

greetings Stijn

Hi again Stijn, it is recommended by XSim to use a go between (Arduino UNO will suffice) a lot of people using XSim are using the Ard, as its affectionately known, if you haven’t already XSim is a great place to start.

Hi,
my goal is to connect the simtools direct to ODrive. Have a look to the above video. The motion comes direct from the game engine.

You can use the ODrive arduino lib and connect it through an arduino. But I want to use the ASCII interface and my tests are quite good till now.

Register to xsimulator.net and download the package. It’s for free. You need an addin for every game you want to play. That will cost some money. But for testing you can use the lfs https://www.lfs.net/ sim the addon is also for free.

hi,

its me again, how is the project going? I have another question, why is everyone using a carbon tube and not stainless steel or something else?

greetings Stijn

Hi Stijn, how is the project going? mine is slow, waiting on bits :disappointed:

CF vs SS, for me SS was the same price, CF is supposed to be stronger, lighter and looks better :grinning:

and

hope this helps

hi,
thanks for the link, I’ve started the build of the first linear actuator, I’m now waiting on some aluminium

Hi all,

here is an update about the weekend work.

The upper rig chassis is welded.

The cardan also. Comes from a Mercedes SLK :grimacing:.

Now waiting for:

  1. limit switch firmware
  2. CFK tube for the second actuator
  3. base chassis
  4. heatsink for the resistor

Greetings / Zennix

hi,
how much did the cardan cost?
greetings stijn


#31

Hi,
it was a used part from ebay, About 29,- €.

Greetings / Zennix


#32

but you only have one now


#33

Hi,
this is the main joint between the upper chassis and the base chassis. Every actuator will have an little joint at the bottom and a ball joint at the top.

#34

hi,
is the cardan your center of rotation then? or?

Hi,
yes.

#36

hi,
Ow okay I’m making a 6 dof :stuck_out_tongue_winking_eye:

greetings stijn


#37

OK, great.
The goal far far away should also be a 6dof. But we are the first using ODrive for that and I want to keep the cost and effort as low as possible if it fails.

#38

hi
hi that’s also true but normally it should work according to me, am I wrong?

I’m using a 6368 motor so that’s a bit bigger than yours

Hi,
Can you share the ODrive case with us?


you can place it here

Hi,
how did you attach the carbon tube to the ballscrew nut?
