Another Competition Robot Parts announcement! This is a project I’ve been working on off and on for quite a while, but I recently decided to make a big code push to get it ready for the 2020 season.
It’s a web-based simulator for linear FRC mechanisms. Linear mechanisms could be anything from an elevator to a drivetrain (running in a straight line of course).
Full disclosure: this is very much a beta version. I’m sure there are bugs. If you find any, send me an email at: firstname.lastname@example.org.
- Up to 3 motor types driving the mechanism at once (any quantity of each motor type).
- Up to 5 stages of gearing reduction.
- Simulation at a user-specified supply voltage.
- Simulation of horizontal and vertical mechanisms (and any angle in between).
- Multiple different options for converting rotary motion into linear motion.
- 4 different motion profiles (constant throttle, trapezoidal, and 2 trapezoidal variations).
- Individual current limiting for each motor type.
- User-friendly graphs (Google charts) for viewing data.
- Generation of CSV data (in case you want to do your own analysis).
Let me know what you think! I would love to hear suggestions of ways to improve it.
- Simulation of, and compensation for, battery voltage drop from current draw.
- Simulation of friction (wheel slip) for wheel-driven mechanisms (drivetrains).
- Torque limiting for avoiding wheel slip.
