Alexander Key

A pint-size robot with a big spirit goes on an interstellar adventure

 Running low on metal, an assembly line spits out something unusual: a peculiar little robot, no bigger than a boy. His name is Sprockets, and though he is small, he has the most powerful electronic brain on Earth. “Destroy him!” cries the foreman, but Sprockets escapes. He runs through the moonlit city, pushing his little body as hard as he can until rain starts to fall—and he begins to rust. But Sprockets is rescued just in time by Jim and his father, Dr. Bailey—a brilliant inventor who sometimes has trouble with fractions. Luckily for him, there is no finer tabulator than Sprockets.
 
 They adopt this little robot as their own, and soon set off for another world—where Sprockets will be charged with saving the universe and learning what it is to be alive.

 Sprockets is the 1st book in the Sprockets series, which also includes Rivets and Sprockets and Bolts.

Sprockets: A Little Robot

Sprockets and his brother race across space to solve a martian mystery

 Life for Sprockets, the little robot with the giant brain, has been very exciting since he came off the assembly line. Backed up by Dr. Bailey and his son Jim, Sprockets has zipped across the stars, having fun all the way. Now it’s time for his greatest adventure yet, and he has someone new to help him out: his little brother, Rivets, who’s pretty handy in a pinch—even if he does have one or two screws loose.
 
 Dr. Bailey is working day and night to perfect an interplanetary radio, but Sprockets and Jim build one in a single night. When their new contraption picks up a signal coming from Mars, Dr. Bailey sends Sprockets and Rivets to investigate. Pursued by a mysterious gang of Mongolian researchers led by the fearsome Vladimir Katz, Rivets and Sprockets must escape the red planet with all their gears intact.

 Rivets and Sprockets is the 2nd book in the Sprockets series, which also includes Sprockets and Bolts.

Rivets and Sprockets

Captured by spies, a robot dog fights to return to his master 

 The Consolidated Mechanical Men Corporation makes all sorts of robots, but it has never produced a robot dog. When Bingo Brown, grandson of the famous navy inventor Commander Brown, sends in a request for just such a marvel, the engineers do their best, but no matter what they try, their standard brain just won’t fit inside the pooch’s head. Finally, they shave a bit off either side of the gray matter, and the result is Bolts: a scrappy little mutt with razor teeth, a razor wit, and a habit of speaking his utterly deranged mind.
 
 When a gang of Mongolian spies searching for Consolidated’s new superbrain diverts Bingo Brown’s shipment, the puppy puts up quite a fight. On the run from spies and desperate to find his owner, Bolts will prove that his bite is just as bad as his bark.

 Bolts is the 3rd book in the Sprockets series, which also includes Sprockets and Rivets and Sprockets.
