You could let your robot drop a block of white bricks (like 8x8x8 studs bug) and then let it turn until the light sensor on the other side picks it up. you could use a wire attached to the block to retrieve it into the original position. (25 years ago, 16-Nov-00, to lugnet.robotics)

Or make the extending "foot" actually turn the robot and use some mechanical stops to ensure it only moves through 90 degrees. Admittedly, this would not be an elegant solution : ) (25 years ago, 16-Nov-00, to lugnet.robotics)
