AISD ROVLatest update April 10, 2015 Started on September 18, 2014
To get video footage, we have mounted a GoPro camera on the top of the ROV. This has caused some buoyancy issues. we are planning to attach a piece of foam on the GoPro to make it neutrally buoyant in water. That way, When we use the GoPro, it won't effect the buoyancy of the ROV.
The ROV was almost assembled and we ran into a malfunctioning ESC. The starboard motor would only run one way. If we tried to make it run the other way, it wouldn't respond. It took us several weeks to isolate the problem. When we did, we replaced the ESC with one from the mark 1 ROV and the motor worked fine.
Work on the ROV mark 2 has gone well. We had gained a little experience from the work we did on the mark 1 so we knew how to avoid the mistakes that had been made there.
Because of the rust on the motors on the mark 1, we investigated how to fix that. We found a link in the instructions that showed how to epoxy the motors. We epoxied the motors (it wasn't the neatest job, but was effective).
By the end of the first semester, the ROV was assembled, but still had major leaks and engine trouble. After much thought, we decided to retire the Mark 1 and began on a second kit that had been donated to our school and multiple others by the Phil Knight Foundation and other anonymous donors.
At the start of this School year, most of the team was unable to continue work on the ROV. Only Teacher Jason Pipkin and one other student were able to pick up project. As with last year, we had to work through all of the problems that that the team had run into or created. Most of our work was troubleshooting.
The OpenROV project started at Metlakatla High School during the 2013-14 School year. At the start of the year, the STEM students were deciding on a project to work on. They had seen the OpenROV on TED Talks and were interested in it so they contacted David Lang, who generously donated an ROV kit for the students to work on.
