Tracy, Nope. Work sure does get in the way of fun. I'll be watching it tonight. Rick ... From: Tracy Eib To: ScienceCentralRobotics@yahoogroups.com Sent:...
Tracy, Still no videos. Apparently ExSpurt won UNI with Thin Man (by Bob Cook, Vancouver, with relatives in Fort Wayne) in second. Almost time to leave for...
Rick, Yes - I saw the tail end. Congratulations! I think ExSpurt's handlers were more in tune with your intended instructions this year. Thin Man is an...
who someone would contact if they wanted OTS to come to their venue. Probably the outreach coordinator, but that isn't necessarily true for everyone, plus the...
I see on the schedule that the Robotics Faire is on August 2nd, in just two short weeks! Wow - that time went fast. If we are planning to participate, should...
Hi Tracy, Two weeks! I'm just getting back from four days in Ann Arbor and haven't thought about robots. We (Science Central and I) have been talking about a...
Ye Olde Robotics Faire is this Saturday, August 2 from 11:00 to 3:00. We should have lots of robot related displays and demonstrations. The plans are to have a...
I came across a great tip for anyone (like me) who is trying to build a robot around the Tamiya double gearbox. These are great low-cost ($10) motor-gearbox...
Tracy, Your meter is intended to measure steady state voltage. It has low pass filters to eliminate any variable voltage. When you try to measure the PWM...
Rick, OK - thanks for the warning. I do not want to damage the motors. Do you think running the 7.4V through a couple of diodes to bring the voltage down...
Tracy, I'd use the 7.4 Volts. Your motor control should drop about a volt or more when it passes a lot of current. Just take it easy on change of speed and...
Rick, I was thinking about what you said about the BJT motor control taking up a volt or more at higher current. Although my line follower does not need the...
Tracy, I haven't seen this one, yet. It looks good. I assume that it is the same control that they are using it their 3pi robot. It will handle those motors...
Rick, I received the motor driver yesterday, but I am quite occupied trying to get my line follower more interested in following a line. I just started...
Tracy, I didn't know that super glue was an insulator. Normally, when I have that problem, I can't get the DIP in the socket or I can't get it out. It's been...
Rick, Yes, well, I did have trouble getting the DIP in there, but I stuck a pin in the socket to break the glue. There must have been an clear coating farther...
Tracy, The BS2 has plenty of power to do the Line Maze. The best instructions for Line Maze were written by Mike Dvorsky (CIRC Yahoo groups under files. Look...
Rick, That is a great expanation of how to program a line maze robot. Thanks for the link. Also, thanks for the head's up on the white on black. I intend to ...
... just read some of this thread. Rick, I found it simplified things a great deal to convert the Lat/Lon points to simple X/Y points. This incorrectly...
Steve, I'm sure that the GPS inaccuracies far outweigh all other possible errors, but this stuff is fun. I am using little bits an pieces of code from several...
Lou, Could you please post the 2009 NEIRG Flyer as a file on this group? Our local hobby shop has a bulletin board that I thought I might post it there if it...
Rick, Saturday I finally got to work on the h-bridge from Pololu. It worked great! After checking the datasheet, I just wired PWMA and PWMB high and...
Tracy, All that I can say is that I've been there and done that way too many times before. It is good to know that the little H bridge will be easy to...
Steve, The compass and encoder are working very well. I expect to come close to the finish pylon with just the compass and the encoder and several runs to get...
Rick, Thanks for the update on everything. You have been very busy. RoboMagellan sounds wonderfully complicated. I need to read up on whole RM concept...
