Re: Complete Autonomous Robot
Quote:
A lot of people (ok, like 3) on here are talking about robotic cars. I competed at ISWEEEP and was next to the romanian kid that (got first and) made a completely self driving car with the opencv libraries. We've been talking since then and have been working on some projects together. The most ideal method would be doing a slam of the environment 30 times a second, but that is impossible, so we have to keep our data flow limited, but useful. The two depth cameras should be plenty. The A star will have to be able to decide which depth feed to use, but that wont be too hard. I've already discussed knowing position and rotation as well. But, an issue that could occur is if we are not getting a solution from the rgb camera. Then we would have to rely on our gyro. A team last year at terre haute spent 30 minutes with us going over how our vision worked just so they could block it and so we could not shoot at all 3 targets. They just put up a pole to keep the target from being a closed contour. It was really clever. I wasn't even mad. I was lazy and didn't put a bounding rectangle when around contours when there wasn't a solution. (only do it if there isnt a solution. It will shave a few microseconds off the program). That was my fault. Oh well. I learned my lesson. "Would it be hard? Yes. Would it be impractical? Probably. Could it be done in 6 weeks? Probably not. Is it innovative? Absolutely." Hard? Our team is up for the challenge. We aren't the most famous team in Missouri (cough cough 1986), and have only actually won one regional in our existence, but we are gaining attention through our software. Impractical? to the extreme. I just want to do one operation completely autonomously during a game. To see our drivers let go of the controls and for us to be still scoring points. 6 weeks? No. That's why we build 2 robots XD. And I may be going into the hospital soon for IVs for 2 weeks, so that's what I'll be doing for those 2 weeks. (no worries about my health, just have a bug that I can't shake) |

Re: Complete Autonomous Robot
Yes, we are still going for it. We are going to do cascade training on our 6 wheel robot to act as a teammate during the build season. We will track the wall (obviously) and use it to know where we are on the field. Simple math allows for you to calculate the speed of a ball on the ground and then the robot can autonomously go to where it will be to pick it up.
Cascade a friendly robot, calculate their speed and pass them the ball where they will be. Find the ball in mid air and automatically go to where is will land to catch it. Lastly, in a mode where our other 2 robots cant do anything (broken or otherwise), find ball, shoot it over truss, get it back, shoot it into target. I'm really tempted to write all the code real quick, but...I'm a senior and that would really not be good if a student didn't know how to do this next year. |
