Homebuilt ROVs Forum

We have to measure the length of many different objects. For example we need to measure a "iceberg" that's made out of pvc. It has to be accurate to about 5mm. With lasers wouldn't refraction be an issue?

So for the mate completion this year we need to measure ALOT of stuff. But in past years we tried slapping on a tape measure on it. But I want to use a more eligent solution . But I also don't want to spend an arm and a leg.
Thanks

I have a brushless motor that had a 3 mm shaft on it. I need to waterproof it but I can not find a 3mm seal anywhere! Does anyone know where I can get one from? I really need it.

Thanks-

what are you doing for your thruster housing? im working on making some brushless thrusters but the housing has stumped me.

Which u cup seal? They have so many different kinds. And also do you know the difference between the u cup seals and the oil seals.

Glad to see you started a thread. I feel your pain on the small school thing. The team I mentor comes from a private school with only 50 in the high school. Three of the 7 seniors were on the team. We had one 50 minute team meeting a week and the rest of the work was done after school. Very cool th...

That is awesome to hear! keep up the good work.

Ok so this is my first post. I go to a small school with only 200 people in the whole high school. So this means that my school doesn't focus much on engineering. So everything done with this rov is completely on our own time after school. So why not start from the most important part...... the cont...

thanks for the responses! so I guess we will just be going with our old thrust setup.

My old rov set up was two up and down, two forwards and backwards, and two opposing horizontal motors for strafing and turning. would this setup be able to be switched over to a vectored setup? would I be able to do all the same things? what are the pros and cons of a vectored thrust setup?
