Ri3D at Purdue is a student organization at Purdue made up mostly of FIRST Alumni from a wide range of teams. This is the organization’s first year and we will live streaming and posting videos over the next 72 hours.
We will be live on Twitch (Twitch) from around 9 am to 10 pm on Saturday, Sunday, and Monday.
We made a lot of progress on day 1, mostly prototyping, building field elements, and coming up with strategies. The videos of the strategies and ideas are up right now on our YouTube channel (https://www.youtube.com/@PurdueRobotIn3Days/videos), and videos of some of the prototypes should be out shortly.
All the day 2 videos are up, including a day 2 robot recap which can viewed here (https://www.youtube.com/watch?v=HNmldRb9Qrg). We are also going to be live on Twitch (Twitch) until about 8 pm or when we finish the robot. Over the next few days, we will be posting longer write-ups all about the prototypes and the robot.
After many long hours of making the robot and the update videos, we are finally ready to share the final robot with the world.
As a first-year Ri3D team, these last few days have been a huge success. There is still a lot of documentation that needs to be cleaned up over the next few days and will be posted on youtube and this thread below. Feel free to ask any questions here and over on the YouTube comments.
We are posting more videos that we took of the robot right before the end of the 72 hours going more in-depth over each of the major subsystems which can be viewed here https://www.youtube.com/@PurdueRobotIn3Days/videos. CAD and other documentation will be posted here once it gets polished up a bit.
I made the hooks in a few minutes, and they need some fixing up to make them work better. We will be posting the CAD along with some other surprises in the coming days.
We had a ratio of 10.71:1 because that is all that we could do because we ran out of planetary gearboxes. According to AndyMark, we should have gone with something closer to a 16:1.
I am very sorry about the delay, the CAD for the full robot has been done for more than 2 weeks, but we have been struggling with Onshape sharing due to how our team is set up. Worst case, it should be posted by Monday because I will reupload the steps and remake the assemblies on my own account.
We apologize for the delay in posting the Cad and are now finally able to release the robot Cad after many issues with Onshape link sharing. The Cad is not perfect due to us only using a super sketch and only putting the parts that we laser cut within the 3 days. Most of the Cad was done over the few days after the end of Ri3D and feel free to ask any questions about the Cad below.
Also after the 3 days, I realized that the hook design that I made was better at grabbing onto the hook which can be seen in the 3v3 exhibition match at Kettering. The hooks did have a problem where they liked to roll too much. So I redesigned a new version of the hook which can be seen at the link below.
We as a team apologize for the inconvenience and delay in posting our CAD late. This was our first year doing Ri3D at Purdue and our team is meeting together to discuss our achievements and fallbacks from this year’s experience. Thank you for the community’s positive messages and suggestions. We will definitely continue to improve ourselves in upcoming years and improve our documentation and communication platforms. Again, we apologize for the delay with CAD being made publicly available, and we wish all the teams the best of luck with their Crescendo season!
