Hardware systems were designed to support different types of parasitic mobility:

1) Active Node Design based on the natural behaviors of fleas and ticks. This hopping robot can sense a nearby object, hop at it or onto it, and attach. It is 40mm tall x 30mm wide x 30mm deep and contains a hopping piston and a planetary-geared motor.

2) Semi-Passive and Passive Node Design: These nodes have semi-passive and fully passive attachment/detachment mechanisms. The electronics were enclosed in a plastic sphere (diameter= 2in.) For semi-passive nodes, the surface is coated with a polyester double-sided adhesive tape. For the passive nodes, a silicone adhesive is used.

3) Value-Added/Attraction Node Design: The basic spherical node, with its full-spectrum LED, displays attractive patterns that catch the eye of a passerby. Once attracted, the host can receive instructions from the node. For example, a label can provide instructions to the host. This can be combined with a reward (i.e. discounts on purchases while carrying the node.)
