RoboSub 2019 Report

RoboSub 2019 Report

RoboSub ended a couple of weeks ago, and we had an absolute blast! Eleven of us flew to San Diego for nine days to get Cthulhu, our new robot, up and running in the TRANSDEC. (Click on “Cthulhu” to see our team video and journal paper.) Above: Duke RoboSub 2019 team (from left): Samuel Rabinowitz, Neil Dhar, Eric Jiang, Nathaniel

Fall 2016 Wrap-up

Fall 2016 Wrap-up

We began our year with Bot Battle as a way to introduce underclassmen to both members of the club and the robotics fundamentals we work with. Partnering with the Innovation Co-Lab, we prepared kits, held office hours, and led workshops covering topics from controls to Arduino basics. In the final tournament, each robot fought in rounds against three others, who they

Bot Battle 2016

Bot Battle 2016

In 2016, we hosted the first Bot Battle competition designed to get students excited about autonomous vehicles and robotics. The competition took place from 9/24/16 to 10/2/16. Twelve teams came out and competed- each building an autonomous mobile robot with different strategies for staying alive and taking down rival bots- but there could only be one winner. Congratulations to our Bot

8/2/16 – Robosub 2016 Report

Robosub 2016 has come and gone already. It was a wild ride, and we couldn’t be happier with the way things turned out. Eleven team members flew out to San Diego from across the US, putting their internships and projects on hold for nine days to hack hard, test the bot, and compete at the TRANSDEC. Our team ended up qualifying for semi-finals.

5/2/16 – More Tests

We have finally mounted the DVL, fresh back from Teledyne after receiving a tune-up. We are continuing to fine tune the controls in a series of recent pool tests. Next step, finishing up acoustics and testing the system on board.

4/18/16 – Full Integration Testing

Last friday we executed our first fully-integrated test. This involved carefully sealings all the pressure hulls, loading up the golf cart with the robot, the support frame, the ethernet reel, buckets of supplies, laptops, and four people. It took us two trips to actually get everything. I think we can actually reduce it to one in the future. In the pool, we used the frame

4/8/16 – E-Social Robot Unveiling

This Friday, we hosted Pratt’s E-Social. This is basically a free-beer-and-pizza that our school helps sponsor every Friday for engineering students. We used it as an opportunity to unveil our new robot for the first time to the community. Reception was positive! Next time: better demo in a swimming pool?

4/7/16 – Potting Moulds

We are in the process of potting our cables to their respective Seaconn/Subconn counterparts. This process involves soldering the wires end to end, securing the connected cables in the 3D printed moulds we made, and pour potting epoxy into the moulds. They take 24 hours to cure, and we use a chisel to remove them. This stuff is super toxic, always remember

3/22/16 – Frame Assembly

3/22/16 – Frame Assembly

The sub is coming together! We have mounted the horizontal thrusters and attached the pressure hulls to the frame. Mechanical is now working on attaching the hull connectors. We aim to do our first swim test next week and begin tuning our PID controllers.
