Connection definition for robot

The connection strategy for the truss relies on the principle that we can precisely machine each connection face so that their relative positions are correct. This means that although our scanned mesh geometries are not perfectly precise (we find errors up to about +/- 20mm) we can use the accuracy and repeat-ability of the robot arm to ensure that connections will match.
As shown in these images, we define the connection machining volumes (that the robot will rout out – in red) in the global geometric frame and then re-orientate a connection set for each fork’s local reference geometry the matches the coordinate system in the robot cell. This local geometry is based on the 3 reference holes that we drilled in the 3d scanning process.
