  • 2017 Swerve Drive CAD & Code Release Over the 2017 offseason, Team 4774, The Drop Bears, have been working hard on developing our own Swerve Drive system. The project has advanced to the point where we anticipate using our design in build season. As part of this, we are releasing the designs and code that we have developed for these modules, as required by the rules. The mechanical design for the modules was developed on OnShape. All of the CAD and drawings on OnShape are available at this link. The code for the Swerve modules has been developed in the open on GitHub, and as such it is available on the team's GitHub. It is written using the RobotPy framework in Python. The code is structured ...

  • Week 5 - Build Season 2017 Week 5 of build season was very busy and hectic for The Drop Bears!In Mechanical, the section remained focused and hard working as they came to the end of the build phase. The climbing group had completed their game piece to a high standard and were very proud of their efforts. Soon after, they were able to mount the mechanism onto the drive base - it was all coming together. Gears completed their design and worked on creating and approving drawings so that the fabrication process could be started. By the end of the week, some components were finished but unfortunately the entire mechanism was not able to be completed.The drive base group worked on the bumpers to make ...

  • Week 4 Update - Build Season 2017 Week 4 of build season was one of our busiest yet, however our designs were coming together and our robot was starting to form.Mechanical was under the pump this week to finish a long to-do list. The climbing group had completed their CAD to an impeccable standard, and drawings had been made and approved. They then moved on into the fabrication phase to get their game piece completed and on the robot. The gears group was working on the very challenging design for our active mechanism. It was a tedious process, but one of the most complex mechanisms we have ever designed, so we needed to do it properly! Hence, the week was spent doing CAD, design meetings ...

  • Week 3 Update - Build Season 2017 Week three of Build Season was very busy for The Drop Bears. As we moved into the high level design phase, most of our days were filled with CAD, Design reviews and more CAD. Although this was a tedious process, we all understood that this was the most important part of creating a good robot.The climbing group was working hard and finished their final CAD at the beginning of the week. They then set off to create their drawings before final fabrication. As our team values our quality control procedure, we made sure every drawing was of high quality and signed off before anyone went down to the workshop.The gears groups continued to work on their CAD over ...

  • Week 2 Update - Build Season 2017 Welcome to week two of build season 2017! It was a very week busy as usual. As we moved into the prototyping phase, groups set out to make and modify the designs from week 1. The climbing group was off to a great start, they were able to produce their design and have a fully working prototype. At the end of the week the robot was able to climb at 100% accuracy. The drive base team has fully assembled the drive base and a temporary electronics board has been placed on to practice driving the robot. The drive base chassis has been fully CADed as well as bumpers and electronics. Driver training has been going well with our drive team ...
