UF electrical and computer engineering master's student Andrew Gray and his pet parrot, Pepper, have been getting plenty of attention worldwide with their beak-driven "Bird Buggy". Gray created the robot for the College of Engineering's Intelligent Machines Design Laboratory course, in which students work all semester to create autonomous robots. When it's time to put the bird away, Bird Buggy is able to dock itself to a base station utilizing a web camera. The students are required to develop their own ideas and find the appropriate parts.
I like referencing Vernor Vinge's A Fire Upon the Deep, specifically his skrode, a machine designed to help a species attain its potential.
Sometimes, aliens need help in alien environments. See the martian perambulator from Between Planets by Robert Heinlein.
