This is a project I started a few days ago. I mean to have it finished before summer 2022.
I love how it lands the wheelie at 0:18 ;D
Like someone said on Discord, I really need a little action figure on there!
The Simtools plugin for GPbikes is outdated unfortunately, so for the moment I am stuck with mgp18..
I have started looking into rewriting the plugin for UDP instead, should solve the 64-32-bit problem.
Very interesting. Good job!
Wow. I have also a project but 2dof only. Good job !

Cool! How's it going?
Are you running it straight from gpb export or with something like simtools in between?
I'm plannig getting data from the same output as Max use for his MAx HUD plugin. It is still in plan phase, nothing really started, but i will also start from scale model like your's
Just wanted to say that the stuff you're doing is awesome and it's so much fun watching your projects progress over time.

Thanks David! I appreciate that! :D
I agree. With David. Congratulations to the progress you've made so far.
I'll keep you posted with progress.
That looks really cool. I'll be following this and might take some idea from you for my motion ;D
What do you think about adding a traction lose?
The prototype has traction loss, it's just that motogp18 doesn't output that.
The rig will have 4 dof:
- Traction loss
Sway can be somewhat simulated, but I'm not sure how useful that effect is.
The motors and electronics just arrived and are waiting for me to pick them up at the post office.
In two weeks the design phase starts, not long now! :D
Nice! Looking forward to it. Do you have an x-sim build thread?
Me too. Have been looking forward to this for a looooong time!
There is a thread at xsim, but not sure where I will focus on updating.. There are many places 😆
Traction loss is yaw?
Not exactly yaw. Rather rotation with center point somewhere around where the front tire contact patch would be.
Front traction loss will have to wait until V2, It's kind of pointless to simulate 99% of the time since it usually can't be saved anyway. The handlebars will have to convey that instead.
I wonder how all this will be perceived by the "popometer".
Not sure it will show on such a device ;D
I don't know. If you manage to utilize gravity in the right way, a well timed heigh shift could be sufficient to trigger the tingly feeling that makes you pucker up.
Have you thought about some strap support system that helps you stay on the bike as compensation for the lack of cornering forces?
What about putting a few electrodes into the seat to give you some small current when the rear is sliding :D :D
There are many things I want to research when it comes to output and input data translating into motion.
Electrodes in my ass is not one of those things!
However, there is a detail in vehicle simulation that gives researchers trouble. That is that there is no real fear of crashing or failing, so the results aren't always relevant to real life.
The groin electrocution would change that.
I'm not 100% sure I understood what the "popometer" is.. :)
"Popometer" is an established term in racing german which translates to "ass-meter", or the feeling you get from your ass over what the vehicle is doing. Specifically rear slip and yaw angle.
The electrodes (or metal seat surface) are not supposed to replace the pain of crashing, it's supposed to replicate the tingly feeling you get when your bike starts getting light at the rear. Similar to when you are standing next to a steep cliff etc. you get what I mean.
An alternative would be pressure outputs at different zones, similar to how F1 teams simulate Gforces.
There will be shaker speakers in the seat and tank to be able to communicate popo-feelings! Those in combination with rig motion should be enough if triggered correctly.
I wrote some wheel spin code for simhub which seems to work very well.
Monday I finally get to start working on this. Some of the hardware has arrived, so electrically we're pretty set except for cabling.
Heck yeah! Looks like a good project.
What motors did you get?
Also, on your scale motors did you print some levers to go on the end of the motor shaft? I can seem to find any levers.
Good luck with the build!
440W 60Nm something. It's going to be interesting!
I just used normal servo horns and some rc car spares I had lying around.
