Question about a circuit

http://livedoor.2.blogimg.jp/robolabo/imgs/e/b/ebb5adcd.png HI could someone tell me how the following circuit affects the signal of the gyro sensor? XV3500CB is the gyro chip. Vref is the reference voltage and Vout is the output voltage of the gyro. Could someone please explain to me what the op a...

Re: Straight lines

gearing up would take too much space. the m motors are small and fast. nxt motors are just too bulky.
the nxt motors just take too much space, especially when my project requires the robot to be as small,accurate and fast as possible.

Re: Straight lines

the nxt motors are much too slow. i need a fast motor for my project. how about using a differential from both motors? so eg when it goes forward, the differential turns but when the robot is turning, the differential stops. then accuracy wont be needed, so i would have no problems using the rcx rot...

Re: Straight lines

well its not hard to get absolute heading from a gyro.
just integrate the rate of rotation.
i need my robot to turn as well, so i cant use a single motor.
how about using two of legos old style rotation/angle sensors?
is that a good idea?

Straight lines

hi, for a project, i need a robot to go in a perfectly straight line.
i am not using nxt motors, but pf m motors. is there a way to sync them together?
i am planning on buying a gyro to help me with that but i wanted to know if there was a better alternative.
i am using nxt-g btw.
