Screw wheels, treads or walking. For some robots and vehicles, their sole means of mobility is jumping or hopping around, as silly as that might seem at first glance.

In reality, this is a Justified Trope as this enables robots to actually walk and even climb the stairs without actually having any knees to bend, which simplifies their construction, albeit can leave them vulnerable to falling over.

See also Spring Coil.

Examples of Hopping Machine include:


Comic Books

Literature

  • In the Red Dwarf novel Infinity Welcomes Careful Drivers, cars on the Spanish-owned port of Mimas on one of the moons of Saturn are a variation on the trope: they normally employ wheels but can also use hydraulic legs to leap into the air in order to bypass the city's notorious traffic congestion. The first chapter, in which Lister is scraping a living hotwiring cabs for the night and picking up fares, goes into some detail about the disadvantages of this technology.
  • In the opening of Heavy Weather by Bruce Sterling, the heroine rescues her brother using one of these. Later, that brother has some drugs and other items smuggled across the border to him using a one-legged hopping robot carrier.
  • At the end of Bert's Hall of Great Inventions, Bert shows Ernie an electric hopping baby carriage. As in the rest of the book, Ernie is reminded of an animal with similar abilities.
