i as thinking about this when i was playing with the new cyber spider
www.wowwee.com ]
with legs on both sides usually youdon't want the robot to move in such a
way that it is bouncing up and down synchronously it just doesn't look
right....
so what i was thinking for turning was to get the legs to move exactly in a
180 degree phase of each other on opposite sides.
my idea is that you could use a differential to drive the legs, and for
turning the drive motor could be stopped with another motor turning the legs
in opposite directions due to the differential.
now i see the problem of having the extra motor giving drag on the side that
it is on forcing the platform to turn, but maybe there is a way to use some
sort of centrifugal clutch to prevent drive until rotation of the motor. of
course this just came to me: a directional transmission may work but that
would only give turning in one direction. unless, perhaps the directional
transmission could be used only for the turning and still a separate motor
for driving. this would require good programming due to the fact that the
floating motor would have to be between the gears. but i ramble on.
any way i know of the float() command but i still think that the motor would
give drag.
well, i just thought that this would be an idea, no mechanical background
here except for mindstorms.
that is all.

| You could use the 6-Leg Walker "Mushi Mushi 7" at (URL) in the "Master Builder Tutorial" as the platform for experimentation. I thought the design was real good, ie, symmetrical and with no extra parts used. My only reservation was that 'turning' (...) (24 years ago, 12-Dec-00, to lugnet.robotics)
