Spherical robot

Spherical mobile robots have applications[8] in surveillance, environmental monitoring, patrol, underwater and planetary exploration, rehabilitation, child-development,[9] and entertainment.

[1] Other driving mechanisms[8] make use of: (1) conservation of angular velocity by flywheels,[3] (2) environment's wind, (3) distorting the spherical shell, and (4) gyroscopic effect.

The research on spherical robots involves studies on design and prototyping ,[11] dynamical modelling and simulation,[3] control,[12] motion planning,[2][4] and navigation.

Some current commercial products are GroundBot, Roball, and QueBall, as well as Sphero's BB-8, based on the droid character of the same name introduced in the 2015 film Star Wars: The Force Awakens.

Parents could ask Ballie to check up on kids to make sure they’ve completed their homework, for instance, or monitor the types of television shows and movies they’re watching.
