# Hardware

Delta Robotics hardware, the ThermoFlex SMA muscle system, Nitinol wire and springs, and the in-development AeroFlex and HydraFlex fluidic muscle lines

Delta Robotics builds artificial muscles and the electronics that drive them. ThermoFlex is our shipping shape-memory-alloy system; the Nitinol wire and springs behind it are sold on their own; and AeroFlex and HydraFlex are our fluidic muscle lines in active development. Pick a product below to see specs, interfaces, and how to build with it.
