(...) Somewhat unrelated, but does that truck have a tight enough turning radius to actually make the corner? I tried to build a car that could do this and follow the edge of the RoboSports test pad (would you believe I have mispaced the RIS pad?!) (...) (24 years ago, 7-Jan-00, to lugnet.robotics)

I'm trying to get the 8479 Truck following (the edge of) a line. It drives around the whole room, except it doesn't follow the line (RIS 1.5 Test Pad). Is it possible to build a rack-and-pinion steering controlled by the RCX without using a sensor (...) (24 years ago, 7-Jan-00, to lugnet.robotics)

(...) (URL) for the slow response; I've been offline for a bit lately. It was the steering assembly from 8437, motorized with a belt drive. Basically there's an offset axle that pushes two tie rods to move the wheels, which are mounted on ball (...) (24 years ago, 25-Jan-00, to lugnet.robotics)
