| This piece is essential to a CV-joint. The 8880 utilizes this in the joints that connect the wheels with the drive train. In real life, a mechanism, not unlike this, makes possible rear-independent suspension (on vehicles with rear-wheel drive), (...) (25 years ago, 27-Jan-99, to lugnet.robotics)
