Type: Wedge - Fairyweight
Weight: 5.3 oz (150 g)
Created in: 2009

Its structure is made of carbon fiber that, when compared to steel, has a much larger strength/weight ratio. In a design of this minuscule size, a lot of attention is required, because details are much more critical and have larger consequences.

Type: Drumbot - Lightweight
Weight: 60 lbs (27 kg) 
Year of creation: 2007

It is so compact that it has been confused with lighter class robots, but it has sidewalls as thick as Touro, and a drum with a surprising amount of kinetic energy.

Touro Feather

Type: Drumbot - Featherweight
Weight: 30 lb (13.6 kg)
Year of creation: 2008


In weight proportion, it’s the fastest, strongest and most resistant robot from RioBotz. Still, its high-end components work below their nominal conditions, which increases their durability and makes the robot very reliable.
