Building a robot to survive 2 districts, a Regional, a Region Championship, and World Championships (plus 4 - soon to be 5 - off season events) is a challenge in itself. - Jared Russell [more]
Basic design spreadsheet to analyze the pull-in process of a choo-choo type mechanism, for determining the optimal gear ratio and geometry given a constantly-increasing spring load during pull-in
Gear ratio selection is typically based upon theoretical top speeds or pushing power, but oftentimes, this isn't the criterion, and is a poor model for actual events. Sprint distance can play a much bigger factor for agile defense.
In this, we'll take a look at how to optimize based on reaching a certain point first, rather than being as "fast" as possible.
VIEW code update to Team 1153's Autonomous Echo to simplify the model and recording process, and to Lab run more easily on the RoboRio. We chose to forego the ability to sequence small operations, for easier recording and selection of complete autonomous routines.
Based on inputs from several on Chief Delphi. The goal of this version is to get some data points on how long it takes to complete the survey in paper form.
This is an analysis of the forces in a torque-actuated strafe drive, to determine what angles of tilt are required to prevent wheel slip. It is shown that for wheels with a coefficient of friction greater than one, any angle will work.
Overclocked's official release of the 2015 Recycle Rush code for our Scorpion robot! This code brought us all the way to the FIRST World Championships.
Zebravision 3.5 is Team 900’s work done in the postseason of 2015 and preseason of 2016. Our focus has been finding new ways to gather information about our robot’s surroundings. We have been working to integrate the StereoLabs ZED, a stereoscopic camera, into the 2015 vision system with the Jetson TK1.
