My daughter's science fair project last year used an RCX and 3 light
sensors to time a LEGO sled sliding down a metal ramp with a LEGO
light on the opposite side of the ramp from each light sensor, she had
a primitive break-beam sensor. She used the first sensor to start timing
and then recorded the time in the datalog for the sled passing the second
and third light sensors.
The biggest problem was the response time, if the "hill" was too steep
the light sensors wouldn't register the passage of the sled.
She got some very interesting data and learned a lot about accelleration,
etc.

| Hello, Sounds like it was an interesting project. Could you tell me what grade was your daughter in and did she use the standard RCX/Lego Software or something else? thanks (23 years ago, 1-Sep-01, to lugnet.robotics.rcx)
