Developers at Laser Zentrum Hanover (LZH, Germany) are using their two-photon polymerization system to create 100-200 nm structures. The idea is similar to rapid prototyping, but in 3D rather than building with 2D layers. Twin laser beams, generating femtosecond laser pulses focused at the same point in a liquid resin, sweeping through three dimensions, form the nanostructures or microstructures. Two-photon polymerization solidifies the resin at the localized focus area.
Festo's BionicKangaroo combines pneumatic and electrical drive technology, plus very precise controls and condition monitoring. Like a real kangaroo, the BionicKangaroo robot harvests the kinetic energy of each takeoff and immediately uses it to power the next jump.
