Abstract:
1. A system for moving a platform, the system comprising: at least one actuator coupled to the platform so as to move the platform into different orientations; at least one sensor that provides signals indicative of the present orientation of the platform; a user operable control that allows a user to move the actuator so as to change the orientation of the platform wherein the user operable control provides signals indicative of the desired orientation of the platform; a controller that receives signals from the user operable control and the at least one sensor wherein the controller induces the at least one actuator to change the orientation of platform and wherein the controller analyzes the signals from the user operable control and the sensor and when the present orientation of the platform differs from the desired orientation of the platform by less than a pre-selected threshold, the controller induces the at least one actuator to move the platform towards the desired orientation at a first rate and when the present orientation of the platform differs from the desired orientation by more than the pre-selected threshold, the controller induces the at least one actuator to move the platform towards the desired orientation at a controlled rate, different than the first rate that is selected so as to reduce the risk of damage to the movement system and articles on the platform.
