Joe, (...) Maybe a special kernel build for testing purposes that increments the lower sys_time word by 0x4000 instead of 1. This will greatly increase the opportunity for this glitch to occur (from once every 65 seconds to once every 4ms.) You (...) (23 years ago, 13-Dec-02, to lugnet.robotics.rcx.legos)

Thanks for the response. I've decided to stay away from string on the robot as string can get easily entangled, especially if battling another robot. I took a break from trying a design using gears and differentials - I was getting really (...) (23 years ago, 13-Dec-02, to lugnet.technic, lugnet.robotics)

| | Re: Hammer Help

In the prototype I used string and winch to set the hammer. I've decided not to use it on the robot - string can too easily get caught and entangled in stuff, especially if it goes up agianst another robot. On the prototype it works surprisingly (...) (23 years ago, 13-Dec-02, to lugnet.robotics)

(...) The problem he's describing, if it's the same one I have, is independant of the position, direction, and power level of the tower. It seems to have something to do with BrixCC itself. The only thing I find puzzling is that Matt (the other Matt (...) (23 years ago, 13-Dec-02, to lugnet.robotics.rcx)

Steve, I checked in some changes this morning (into cvs) to put the motor controller back at the 1 ms interval. However, I want to complete the get_sys_time() updates that Mark Riley has proposed; so that can be tested as well. I am not sure when (...) (23 years ago, 13-Dec-02, to lugnet.robotics.rcx.legos)

(...) It's funny that you should bring this up - I've had exactly the same problems with several RCX's and downloading firmware from BrixCC. The only solution I've been able to find is to download the firmware using the RIS2.0 software and then (...) (23 years ago, 13-Dec-02, to lugnet.robotics.rcx)

(...) It turns out that the nature of the glitch depends on the order you read the upper and lower 16-bits of sys_time. If the compiler generates code that reads the high word first (which it seems to do), then your example will work. However, if (...) (23 years ago, 13-Dec-02, to lugnet.robotics.rcx.legos)

I was wondering if anybody would improve the power focus for the Lego camera. You have accomplished this very well. I especially like your tilt drive. Sticking that 40 tooth gear without glue is super. Congratulations! Bob Fay (URL) Haye" (...) (23 years ago, 13-Dec-02, to lugnet.robotics)

(...) In trying to balance an RCX on two wheels, every little bit makes a difference. I didn't think it would matter quite that much, but my robot really shakes more with the new version. Thanks for the work, Steve (23 years ago, 13-Dec-02, to lugnet.robotics.rcx.legos)
