| | SCARA, Anyone?
|
|
Just curious... Is anyone else trying to do a SCARA? This is really an interesting robot-concept, and I'd love to see others ideas. Programming has been my main headache; I've not successfully implemented any sort of vector/servo typ drive tasks in (...) (25 years ago, 26-Jan-01, to lugnet.robotics)

|
|
(...) Hallo Ram, you are right that my solution for the Distance Tracker Bot, the interface for the GP2D02 is a real "resource killer". At the beginning i planned to istall two of the GP2D02 at my RCX with this interface. That's the reason i'd (...) (25 years ago, 26-Jan-01, to lugnet.robotics)

|

Yes, there are some chemical sensors available from (URL) other a pH sensor and an oxygen sensor. What sort of chemistry was on your mind? I am profesionally interested in among other glucose sensors, but I never tried to combine it with Lego. (...) (25 years ago, 26-Jan-01, to lugnet.robotics)

Alexandre, My guess would be that the the Motor killed the RCX, It seems to be that the newer Technic motors (i.e. Mindstorms motors) often exibit this failure mode. I have had three go this way, and I have heard reports of other people who have had (...) (25 years ago, 26-Jan-01, to lugnet.robotics)

The outputs on the RCX can sink about 500mA of current, and each motor draws up to 200mA when stalled. You can put two on the output and stall them before the thermal shutoff kicks in. I was under the impression (never tried it, mind you) that the (...) (25 years ago, 26-Jan-01, to lugnet.robotics)

(...) I find it really frustrating that this has to be "discovered" over and over. I believe my fix for LegOS (a year ago?) fixes this problem. The sensor itself is very good. It only ever returns the discrete voltages (which vary by cable length (...) (25 years ago, 26-Jan-01, to lugnet.robotics)
