Analog sticks provide low values in the corners

There is no single best way of clipping joystick inputs and mapping them to control values of your motor.

It is a matter of personal preference, but here is what people have been doing in the past:

What do you think is a more efficient way to drive your robot?

@shota_irl Sure! I realized after posting that I had oversimplified the actual functions that I used. Since it seems like a lot of people found it useful, so I’ll explain it in greater detail Traditionally, you just set the motor equal to the the joystick’s value. This is represented by the dashed red equation y = x (see graph below). In order to get a curve with the following characteristics: You can use the equation with the form: [10%20AM] In this equation n >= 1, x = unmodified…

Optimizing Exponential Drive?

I am curious how you found those “magic” numbers (1.2, 1.0356, 0.2) for the function. Aside from trial and error, it seems a bit un-intuitive. I like to use power functions, because it is straight-forward to visualize how their curvature changes as power changes. I explained these power functions a while back here. I explained my motivation for using these functions here. I encourage anyone to read how to use these functions, and try them out for themselves. I also enjoy graphing in Desmos, s…

Arcade and X-Arcade Drive using full range of joystick without clipping

I responded in a couple other topics about Arcade and X-Arcade drive code. I had intended to post some tables to visualize what is happening in the code but discourse does not make that easy. So I converted a spreadsheet to HTML & JavaScript. You can pull or download the html pages from GitHub here: BTW, I’m sure I didn’t come up with the Arcade Drive equations. I remember seeing something like them a few years(?) back but it still took me a couple hours to figure out the math. If anyone kno…

Also, you could study end of the season code submissions fro the past seasons:

Change Up - Season code request

Worlds for the change up season is over. I watched for many hours yesterday, RECF did a great job to create a virtual event after a difficult year. Congratulations to the winners. Preserve your amazing autonomous and driver control programming forever ! As I do every year, I would like any teams that think their programing may help future generations to send me the code or (preferably) a link to a git repo I can fork, I will add to a github organization as I have done in previous years.
