"An unmanned combat robot. The machine guns on its arms fire high-caliber rounds."
They resemble the Battle Jackets.
In Age 761 a RR Mech Soldier variant called the Rampaging Robots was rampaging in East Ravine. It was noticed by Android 8, who informed Goku about it upon meeting him. Goku dealt with the Rampaging Robots as per Eighter's request.
In Age 767, RR Mech Soldiers and RR Mech Commanders can be encountered in the Far Southern Islands Area where Papaya Town, Papaya Island, and the World Tournament Arena are located. Additionally, RR Mech Soldiers, RR Mech Commanders, & RR Mech Generals can be encountered in the North Mountains Area where Dr. Gero's Lab, the ruins of Muscle Tower, and Jingle Village are located. They are often supported by Red Ribbon Army drones such as the RR Attack Bit, RR Assist Bit, & RR Recovery Bit.
During the ten day wait for the Cell Games, Goku ends up encounteribg a RR Mech Commander named Guard Robot while searching for papers containing information on Android 8 as Dr. Briefs needs them to repair Eighter who has been feeling sluggish due to his internal computer malfunctioning. Goku manages to find the papers he needs but is located by the Guard Robot and his two RR Assist Bit support units. However it proves to be no match for Super Saiyan Goku (and Super Saiyan Gohan if he is on Goku's team). Humorously, Goku is unsure if the Guard Robot is a robot, despite it being obvious. Ultimately, Goku is able to get the papers back to Dr. Briefs who successfully repairs Eighter, who Goku returns to the forest near Bells Village via Instant Transmission.
