Mini Darpa Challenge

[irishninja]

This mostly applies for people in the NYC area, but I'm sure it will give others ideas. In the recent upswing of people who own VEX kits, and after PBS's NOVA show on the Grand Challenge I had an idea. It would be really fun to have a mini darpa challenge with vex/miniature robots. In NY, probably in Riverside or Central Park or something, but I'm sure it could happen around the country. No standarized courses, different for each one. I'd be willing to host the one in NY, although I'd want to enter. The course would be setup on that day with rails on either side so you don't need to rely on gps. It would be much much much smaller, and there would be height and weight restrictions, although they would be loose. However, I need to know how many people would be interested in doing osmething like this, so if you are in the NY area, please respond to this with questions, concerns, or just sure that would be great where do i sign up? For there to a be a prize there wouuld have to be an entrance fee, something like 5 dollars, and winner takes all, or we can donate it to FIRST, or something of that sort. ANyway, please post. I'll come out with some rules later, if enough people want to do it.

I'd love to be apart of it, but we don't Vex and getting my team to do Off Season Robotics is almost near impossible.

It wouldn't have to be VEX parts, I just suggested that because they are a) on sale, I think still, b) easy to get c) easy to work with, and d) come with things that would make this slightly easier. So as long as it didn't break the weight, height, width, length, requirement, and I'd probably put a price tag on it as well, as well as number of sensors, (although they would all be LOOSE requirements, sI'm thinking like 3 by 3 by 3 feet, (probably bigger) or maybe just 27 cubic feet, price tag of like 1000 dollars and max 20 sensors. Depending on interest in it, and people who actually show up, these rules would tighten/loosen. However, I wouldn't reject anybody who fit in these guide lines, just because theyre slow or something. I know DARPA had a pre race race to see who would be allowed in.

There is a competition like this called robo-magellan some information is available at http://www.robothon.org/robothon/challenge.php If you do decide to start your own competition and It is in the NYC area (or closer to RI) I would be more than happy to help you with planning or would atleast like to compete.

I would be interested, but my team is not in the area.

However, if you guys try this out, I'd love to see how it goes, as I might want to host one outside of SVR, or another local regional that I attend.

The rules would generally be the same, but there are some things I would like to change. Also, there would be another competition for people who don't have the programming kit. It would be human controlled as a seperate one, so people who don't have the money can still partake in the festivities. Some rules I would change would be allowing people to measure the course, that woul dbe illegal. Wheel diameter would be restricted a bit, and there would also be limit on number of motors. People could take part in both if they wanted to.

maybe make it really hard and do not limit any hardware, the real hard part will be setting the direction without the GPS but it sounds like a lot of fun

Here is a link to a post I just posted about this topic.

This talks about my Mini DARPA Challenge I am in.

You said you would not need to rely of GPS, you did not rule it out.

You can get GPS units on ebay with serial outputs for $100. Its a great way to get from A to B if you know where B is, but GPS is not a magic solution. You still need to avoid obsticals and not run into other vehicles.

GPS would only be one subsystem of the navigation design.

[Gdeaver]

A digital compass with tilt compensation and a gyro help when the lock is lost. The lazer stuff is big $$$$$. However ultrasonic and IR sensors are very usable and relatively cheap.

[Rohith Surampudi]

GPS is only accurate toa certain degree, for something this small, i mightactually hurt your performance.

Great idea,
using the walk paths in Central Park and Battery Park would be a great challenge course. Probably with permission from the NYC Parks Department a sectioned off area would be given to this event.

Suggestions:
1. For the first year, keep it simple and run two weight classes- FRC and VEX.

2. Create black & white pattern marks along the route for the cameras or senors to detect and to maintain their direction.

3. set limits on size, weight and sensor type for each class of competition.

4. Get some really nice trophies with the team entry fees.

5. Create a team festival or picnic during the event (like a team post-regional social)

6. Lots of planning, logistics and volunteers will make this a fantistic post-season event.

In answer to some questions.

It would not be limited to VEX parts, thats just a suggestion because they are easy to get and to use. If we did have lines i would space them out quite far because otherwise one could just use the line tracker kit from vex to do it. But i would put lines.
