Unmanned system designers are exploring bio-mimicry and hive intelligence. The video of “BionicANTs” below illustrates both trends.

Each individual mechanized ant uses control algorithms to cooperatively solve complex problems. Although they collectively perform a task, each individual ant engages in actions at a local level that are determined by autonomous decision making. Thus, they mimic real ants.

The ants have piezo-ceramic bending transducers in their legs’ actuators, which enables precise control and minimize the energy needed. Stereo cameras and floor sensors allow them to navigate their surroundings as well as identify objects that are to be manipulated. They communicate with a radio module that is located in their abdomen (the next time you are tempted to grouse about fitting a radio component into a small space, remember the challenges facing the designers of these ants).

To build the bodies, the manufacturers used 3D printed plastic powder, which was melted layer by layer with a laser. 3D printing was also used to create the electric circuits.

The ants are also cute, in their own way. I especially like how they use their antennas to charge their batteries.
