Robotics & Engineering - Week of 03/17/25
The first 2 days of shop this week were spent replacing XT30 connectors on the ROV’s power distribution board. There have been connection issues in the past, and I really didn’t want this to factor into existing reliability issues.
On Wednesday, Jonas Wirz and I got the ROV into the pool, however, we had some free time before then and were very productive with it.
Timothy Hunt suggested we insert a temperature and humidity sensor into the ROV for testing purposes. We put it in the tube while Jonas practiced the competition tasks. Due to a faulty seal, some water got into the tube. Our results with the sensor were a bit skewed.
The ROV’s power issue has been solved, and my software based solution seems to be working. A small bit of tweaking will make it more robust. Another issue presented itself as well. The I2C communication for the IMU at times will cut out. Due to a lack of proper handling, the code exits and the ROV shuts down. Some more investigation will help this.
Most excitingly, VECNA Robotics donated nearly $200,000 worth of unused sensors to our shop. The shipment mainly consisted of LiDAR and camera systeming, but it had various other misc. parts and tools.
Ultimately, we plan on putting the LiDAR sensors on the autonomous golf-cart project:
