Throttle reverse issue in basic_motion.ipynb #43

Closed ChrisW0rk closed 4 years ago

ChrisW0rk commented 4 years ago

Hello all, happy holidays!

I am having a strange issue when running the JetRacer basic motion notebook.

When I run basic_motion.ipynb and adjust car.throttle, positive values actually make the car go in reverse, and negative values move it forward.

If I adjust car.throttle_gain to a negative number, that allows positive values in car.throttle to move the car forward.

Basically, things seem to be working in reverse for some reason. Anyone have any clue what's going on here?

Let me know if you need additional info to give an answer and I'll provide what you need. Thanks!

Hi cyte85,

Thanks for reaching out!

Do you mind sharing which car you're using (Latrax or Tamiya)?

I think one of those may require a reversed throttle gain. Perhaps I should document this better if it is the case.

Best, John

Hi John,

I'm using a Tamiya. I actually just set a reversed throttle gain and was able to get it running smoothly with positive numbers for acceleration, so problem pretty much solved. I'll close the issue, thanks!
