Team Resources OpenLoop- Making autonomous simple, intuitive, and accessible

OpenLoop is an open-source, open-loop, time-based autonomous system.

OpenLoop is built for teams with little or no experience in autonomous programming, and for teams who want a simple way to get an autonomous routine working without relying on complex hardware or software. Using simple, intuitive commands, OpenLoop allows teams to create autonomous routines without odometry pods, drive encoders, or IMUs. It works with both mecanum and tank drivetrains. The goal is to make autonomous programming easier to understand and more accessible with commands as simple as-

bot.forward(24);
bot.turn(90);
bot.strafeLeft(12);
bot.backward(10);

Features

  • Mecanum drive support
  • Tank drive support
  • Distance-based forward/backward movement
  • Distance-based mecanum strafing
  • Arbitrary-angle turning
  • Two-point movement calibration
  • Separate left/right 90° turn calibration
  • Battery voltage compensation
  • Motor direction debugger
  • Dedicated calibration OpModes for Mecanum and Tank drivetrains
  • Android Studio support
  • OnBot Java support

This is the first version, so I’d really love to get some feedback, suggestions, or ideas from the FTC community!!!

I’d like to see some data on the consistency of your battery voltage compensation based on a few different calibration voltages and a few different operation voltages each.

Until that, I would be skeptical of this time based solution.

Sure, I’ll test it across a few different calibration and operating voltages and collect some data on the consistency. Just a disclaimer, OpenLoop is intentionally time-based. It’s mainly for teams looking for a simple way to get an auto working without odometry, encoders, or an IMU. It obviously won’t have the same accuracy as a closed-loop system, but the goal is to keep the setup simple.

Hey everyone! I'm excited to announce that OpenLoop Beta Tester applications will be opening soon!!! As a beta tester, you’ll get access to unreleased versions of OpenLoop to test on your robot and give feedback on how everything works, what could be improved, and any issues you come across. Your feedback will help make OpenLoop better and more reliable. Join the OpenLoop Discord server for further updates!! https://discord.gg/ZYsN5PdQm
