HiTechnic has released a new motor block that you can use in NXT-G. Here's an excerpt from the description found on the HiTechnic website . Why the HiTechnic Motor PID Block? This block is an alternative to the standard LEGO Motor Block. Unlike the Motor block, which when used with a duration of degrees or rotations, gives you relative control over the position of the motor, the PID Block is designed to give you absolute position control. With the standard Motor block, you might use it to go forward 45 degrees, go another 45 degrees, then go backward 90 degrees. Each time the motor turns an amount that is relative to the position that the block starts in. With the PID Block you specify an absolute position. For example, if you want the motor to go to position 45, you can pass in that value to the Set Point input of the PID Block and it will drive the motor to that position. If the motor starts at position 100, then it will go backward to 45; if it starts at 0 then it will go forwar...
