A Training Robot is one of a series of floating, spherical robots used to help warriors practice combat techniques. They have a blade for one hand and a blaster for the other, allowing them to utilize both melee and ranged attacks. Teela has been known to hone her skills by fighting Training Robots, though she once needed He-Man's help to defeat one.
Training Robots can be set to operate either automatically or by remote, as seen when Orko controlled a Training Robot that Teela was fighting and later fought one on his own.
