Pump selection for parallel pump control is critical in determining the desired total system output. Check pump curves to make sure that the number of pumps, flow, head, and multi set points are adequate for your system needs. Head pressure may not remain constant in some cases, as the flow is increased to multiple pumps. Courtesy: Crane Pumps & Systems.

A new MIT-invented system automatically designs and 3-D prints complex robotic actuators optimized according to an enormous number of specifications, such as appearance and flexibility. To demonstrate the system, the researchers fabricated floating water lilies with petals equipped with arrays of actuators and hinges that fold up in response to magnetic fields run through conductive fluids.
