Fabrication of Composite and Sheet Metal Laminated Bistable Jumping Mechanism

At a layer-based manufacturing method using composite microstructures, fabrication method for embedding an elastic component at an angled position is developed. Sheet metal is used as an elastic component, which is stamped after the layering and curing process, thereby changing the neutral position of the spring. By using this fabrication method, a small-scale bi-stable jumping mechanism is fabricated and can jump to a height 175mm with an initial takeoff velocity of 1.93m/s.
