Orthogonal Cross Mill is a hands-on, mechanical & electromechanical interactive exhibit manufactured by Hefei Panda for science centers, children’s museums, discovery centers, STEM learning centers and family entertainment centers. Engineered for durable, robust, low-maintenance, high-traffic gallery installation, it turns abstract scientific concepts into direct, interactive visitor exploration. Hefei Panda is a global exhibit manufacturer exporting hands-on science displays to 50+ countries, with in-house engineering, fabrication, installation and commissioning.
Exhibit Summary
Orthogonal Cross Mill is a Mechanical Interaction interactive exhibit in the Mathematics category, designed for science centers, children’s museums, discovery centers, STEM learning centers and family entertainment centers. Built as a hands-on, mechanical & electromechanical display, it turns an abstract scientific concept into direct, interactive visitor exploration, and is engineered for durable, low-maintenance, high-traffic gallery use.
Scientific Principle
Demonstrates the working concept of the Cardan ellipse compass. Rotate the handle, and the two fixed-distance slide blocks attached to the handle link move orthogonally along the cross groove in the grinding plate. The handle always moves on an ellipse due to the constraints of four forces - the linear motion constraints of the two slide blocks and the rotational motion constraints between the rocker and the two slide blocks. The distances between the handle and the two sliders are the major semi-axis and minor semi-axis of the ellipse respectively.
Operation
Demonstrates the working concept of Cardin's elliptical compass. Rotate the handle, and the two fixed-distance slide blocks attached to the handle link move orthogonally along the cross groove in the grinding plate. The handle always moves on an ellipse due to the constraints of four forces - the linear motion constraints of the two slide blocks and the rotational motion constraints between the rocker and the two slide blocks. The distances between the handle and the two sliders are the major semi-axis and minor semi-axis of the ellipse respectively. Press the rotating rod, watch the reciprocating movement of the two slide blocks along the cross chute on the disk, feel the 360° rotation of the rotating rod, and watch the trajectory of the end point of the rotating rod.
