(...) I think that NiMH should be up to the task at that power level (difference between NiMH and NiCd occur at much higher discharge rate). But maybe there is one or more dead cell that cant't hold its charge? Since NiMH provide 7.2V instead of 9V, (...) (19 years ago, 19-May-06, to lugnet.robotics)

(...) The Lego geared motors can pull about 250 mA when stalled, and close to that when heavily loaded. So for three motors, that may be more current than your batteries can deliver. Rechargeable batteries, esp NiMH, don't deliver the same peak (...) (19 years ago, 19-May-06, to lugnet.robotics)

Can someone from the MDP comment on how multiple robots using the ultrasonic sensor interact. It is possible to use this sensor reliably when one or more other robots nearby are using theirs? -Tim (19 years ago, 19-May-06, to lugnet.robotics)

ok, I finally got to trying some of the stuff you recommended. I recharged the batteries and tried downloading the firmware. It can run the whole program without the motors being plugged in. It can even run the program with all motors plugged in but (...) (19 years ago, 19-May-06, to lugnet.robotics)

Hi Andrew, (...) there are actually 3 I/O lines on each sensor port: - 1 legacy sensor A/D with appropriate power supply on the same line. - 2 digital I/O lines, one of which can also be configured as analog in. The remaining lines are 2 GND pins (...) (19 years ago, 19-May-06, to lugnet.robotics)
