Just wanted to say hello to everyone in the group. I was also pleased at how easily I could make a shortcut to this group on my desktop. (If I don't see it, I...
Welcome to Science Central's Yahoo Groups. The purpose of this group is to promote robotic activity in the Fort Wayne, Indiana area. You may view the posts to...
Hello everyone! My Name is Tracy Eib. I live with my wife and four kids in Bourbon, Indiana. My two sons and I have attended the NEIRG Winter Games the last...
Tracy, It sounds like you are off to a good start. My first robot was a BOE-Bot that my son and I entered in 3Kg sumo. Needless to say, we didn't win a...
Rick, Thanks for your response. Wow - a BOE-Bot in 3 Kg sumo! That would be tough! Yes, the BOE is just a little too long to meet the mini sumo requirements so...
Tracy, It sounds like you are off to a good start on a new sumo robot. If you need anything, just ask. I have lots of old, spare stuff laying around. I did...
Rick, Thanks for the response - and the updated curcuit. I am just exploring feasability at this point. I want to finish the BOE/mini sumo converison before I...
Tracy, Before you get into a full H bridge, I'd suggest a Pololu motor control driving the motors in the servos. Just take out the servo electronics and tie...
Rick, Thanks for your advice. I hadn't thought about gutting the servos. The Pololu products seem like a great way to go too. It really frees up the Basic...
Tracy, I measured a very strong, fast servo and got 3 ohms resistance. If you ran them at 12 volts, that would produce 4 amps stall. Perhaps you are right on...
Rick, Sure, I would love to try that out! That is very gracious of you to loan me that stuff. My wife tells me I am busy this weekend but is next Sunday the...
Tracy, Dec 9 will work well for me. The SN754410 actually have standard (non FET) transistor bridges. Paralleling standard transistors does have some...
I see that the Science Central calendar has a NEIRG class next Saturday, 12/15/2007 as well as one in January. Could someone explain a little more about these...
Shane, Lou, I can do the classes, but I didn't write down the general topics the we talked about for the classes. Also, we do need to set a time, like 1:00 to...
Rick, Did you get my other email about setting up in the Demo Theater? I say we can do it from 1-3 pm. I had Shane update the webpage with that time. I...
Lou, Saturday 1-3 in the Demo Theater sounds great. I can fill up two table with working robots and literature...no problem. I'll be there ready to talk. Rick...
Rick, How did the class go? I could not attend, but I am hoping to attend at least one of the other two classes. Tracy ... table with working robots and...
Tracy, I had a great time at the class. Actually, we have tired to structure things a bit, but it never works out. Over the years, very few people actually...
What will you be bringing to this year's competition? I am planning to have my first robot this year - a mini sumo. Here is an update on my project; The base...
Tracy, It sounds like you are well on your way to an operational Mini sumo. As far as parts go, I've had great luck with QRD1114 sensors in my line follower...
Rick, Thanks for the feedback on the IR sensors. Those were the ones I was planning to get, since I am already used to them after tinkering with the ones from...
Tracy, On the Robo Magellan robot...actually I've been thinking about one for a few years. There has always been other robot projects that were a higher...
Rick, The Robo Magellen sounds pretty cool. Maybe you would consider doing a NEIRG demo? As for the Explorer post - I always though that there must be some ...
Tracy, I don't know how far the Robo Magellan will be by the end of February. It should be running, but all navigation won't be working. That stuff can only...
Hello everyone. I am Jerry Etnier. I teach electronics and computer technology classes at ITT Technical Institute. I have been working with Science Central for...
Hello Jerry! Yes, thanks for posting the great photos of those cool bots. There is something about treads on bots I have always liked... it gives them a more...
Sorry for the delay. I currently do not have any students involved in the robot competition. I am currently working with some area high school students. I find...
Rick, When wiring the Pololu Motor controller, there is an option to have the stamp reset the controller. Do you know if this is necessary? What is your...
