Nasa concept robotic cell
grabcad
In a NASA challenge, two robots with linear motion create a flexible cell for additive manufacturing of spacecraft heat shields. With 3 DOF on X, Y, Z, they print by circulating around the heat shield's circumference, ascending each layer. Material is supplied from a container via cables, supported by pedestals to avoid tangles. The gantry robots initiate printing with head extruders; upon completion, they retract and the gateway opens. The worktable moves linearly for human operator access, detected by a photoluminescent barrier that automatically closes the gateway. A crane lifts and deposits the printed piece before the process is repeated.
