Using Linear Actuators for Articulated Steering

There has been a debate on how to build proper articulated steering with the use of double linear actuators (LA). The problem is that the steering ”speed” will vary over the steering ”cycle” when only using a single LA. As a result, when using double LA:s, there will tensions, that might be large enough to engage the built in clutches in the LA:s. However, depending on how you choose your ”geometry”, this problem can be reduced. This video shows one example of a geometry that will work fairly well, using the mini LA:s. It has been tested in vehicle up to 70 cm / 2 kg.
