(...) I guess - but surely - having an asymmetry in the robot's construction is more likely to cause it not to drive straight than the 1% to 2% due to the motor rotation direction. You may be a 'better' builder than I am - and perhaps be able to (...) (25 years ago, 23-Jan-01, to lugnet.robotics)

(...) Yeah, I saw that. nice work, that. I figured I'd throw it in anyway on the principle that eliminating error of any source is always a noble cause. I like to use worm drives to 'turn the corner' anyway to get the extra torque so it's not a (...) (25 years ago, 23-Jan-01, to lugnet.robotics)

(...) Well, the RCX (the computer "brick" that comes with the $200 Mindstorms set) has Infrared communications with the PC. The amount of RAM in the RCX is rather limited for fancy AI stuff - but plenty for taking simple commands *from* the AI (...) (25 years ago, 23-Jan-01, to lugnet.robotics)

(...) Well, if you read my *long* post from a week or so ago, you'll know that motor mismatch makes up at least 11% of performance, motor direction perhaps 1% or at most 2%, and HOW YOU BUILD YOUR MODEL accounts for at least 7% ... even when you are (...)

(...) No - I'm a Linux user and *none* of the software on the CD would work for me anyway. You don't need spirit.ocx for NQC programming. Download the firmware file from Lego's web site - that (and NQC which isn't on the CD anyway) is all you need (...) (25 years ago, 23-Jan-01, to lugnet.robotics)

| | What specifically is the difference between RIS1.0 and RIS1.5
|

Does anyone have a part-by-part listing of the differences between RIS1.0 and RIS1.5? I am under the impression, for example, that there is a white clutch-type gear intended to permit a motor to continue turning if the drive train/robot becomes (...) (25 years ago, 23-Jan-01, to lugnet.robotics)
