Team 5190's Presentations at NC P2P Workshop

Recently (Saturday, Nov. 23), Team 5190 had the wonderful opportunity to present at the P2P (Peer to Peer) Workshop alongside other teams at North Carolina State University to our local NC teams. We had two representatives: Abhiram (our VP of Engineering) and I who presented to our peers.

Abhi’s presentation, titled “Rapid Prototyping”, went over the stages of quickly prototyping mechanisms through the build season to achieve an efficient final product. The link to the video is available here: https://youtu.be/WPX2YvE85-U

My presentation, titled “Zero to Trajectory Tracking using FRC 2020 Software”, went over how to program a robot to accurately track trajectories from scratch using the new tools available to teams in 2020. That video is available here: https://youtu.be/wqJ4tY0u6IQ

Please leave any questions you may have about either of these presentations below and we will do our best to answer them.

How many intake prototypes did y’all end up building for the 2019 build season?

These presentations look really helpful! Any chance you could post the slides shown in the videos as PowerPoint or PDF files?

We had several designs for intakes throughout the season; probably more than 6 or 7 in total. I’ve uploaded a few pictures with some descriptions down below:

This was a very early prototype of a cargo intake where we experimented with “moons” to hold the cargo ball in place.


This was one of our initial full-fledged designs, with a 2018-style grabber for cargo and 3d printed claws for the hatch panels.

After our first two district events, we were not happy with the performance of the 3d printed claws so we decided to switch to an active wheeled intake design, inspired by teams such as 1323 and 973. To do this, we modified our existing intake.

We used a variation of this intake (with longer hex churros to prevent the hatch panel from sliding backward) at DCMP and Houston.

There were several other designs that we tried out along the way as well, including a ground hatch pickup, hatch intakes with fingers (like 1114), etc. Those pictures are also down below:

This was an interesting design for ground pickup of hatch panels and worked well for cargo, but we couldn’t use it due to packaging constraints with our passthrough.

This was a 1678 style hatch-pickup. Although the hatch pickup worked relatively well, we were not happy with the performance of the cargo intake below it.

The “finger” style design worked very well, but we did not like the cargo intake below it (same cargo intake as the picture above).

I thought Prateek’s presentation was very informative. I’m hoping to see more teams (especially in NC) do more advanced autos this year.

Thanks for putting these resources up, Prateek. I wanted to come down to the workshops, but I had family in for the holiday and couldn’t make it. This will be greatly appreciated by the team (and everyone) as we work on this year’s bot.
