The remote tracking device is an extremely intelligent tracking device disguised as a ladybug. It was created by Dr. Gero to study Goku and the Dragon Team, and gathered genetics from the greatest fighters to create Cell.
The tracking device is created by Dr. Gero after the Red Ribbon Army is defeated by Goku. The design of the device differs at the two points it is shown in the Dragon Ball Z anime, it only appears once in the manga bearing its second design.
Dr. Gero uses this tracking device to study Goku and the Z Fighters for years on end. The remote tracking device helps him to collect cells from Goku, Piccolo, Vegeta, Frieza, and King Cold for the creation of Cell, as well as to collect data from the other Z Fighters. During Android 20's flashback regarding the tracking device being used in all of Goku's battles prior to his leaving for Namek, it resembles a ladybug. While the device continues to collect DNA as it collected Frieza and King Cold's after Dr. Gero stopped collecting data on the Z Fighters battles as he did not know about Future Trunks or the Super Saiyan form which he would have known had they collected data on that battle. It is also implied by Cell that they are controlled by Dr. Gero's Supercomputer to collect cells after Dr. Gero's death.
Dragon Ball Z
Main article: Saiyan Saga The tracking device witnesses the battles between the Z Fighters and the Saiyans, it collects the genetic makeup from Piccolo as he is dying from Nappa's attack, and then from Goku and Vegeta at the end of the battle.
Main article: Androids Saga The tracking device witnesses Future Trunks' battle with Mecha Frieza and King Cold, collecting genetic material first from Frieza after he is cut in half and then from Cold after he is killed by Future Trunks.
During the fight between Piccolo and Imperfect Cell, Cell points out that the device used to track and collect their DNA is observing their battle. To make sure it does not collect anymore, Piccolo destroys it with a Ki Blast. When it appears during Cell's battle with Piccolo, the tracking device's head resembles Cell's in his Imperfect Form, except for the pink eyes.

Video Game Appearances
Ladybug robots that bear the insignia of the Red Ribbon Army are enemies in Dragon Ball Z: The Legacy of Goku II. The ladybug tracking device is also seen in the menu of Ultimate Battle mode in Dragon Ball Z: Budokai Tenkaichi 3.
In Dragon Ball Z: Kakarot, Dr. Gero references his remote tracking devices when explaining how he knows about the Z Fighters. Though they do not appear in-game, there is an archetype of unmanned patrol drones (RR Attack Bit, RR Assist Bit, & RR Recovery Bit) that appear as enemies and resemble a miniaturized Battle Jacket crossed with the Remote tracking devices used by Dr. Gero's Supercomputer to collect cells. In "-Trunks- The Warrior of Hope", there are also old security drones that appear in certain areas. Though originally designed to patrol Red Ribbon Army installations, they have since gone rogue and now consider Earth as an installation (possibly due to Future Android 17 & 18 effectively lording over the planet's remaining inhabitants whom they slaughter at their leisure). The drones emit a detection field that paints a target that enters them causing their alert meter to fill, which will sound an alarm if it fills up completely, alerting the Androids to the presence of potential prey. However they can be destroyed and if their commander drone is destroyed, it will free the area of surveillance. If the Androids are alerted, this leads to an Android Assault Battle, where Future Trunks and/or Future Gohan must fullfil certain conditions to open up an opportuned moment to escape and flee. If they are defeated,during one of these battles they will be admitted to the hospital to heal their injuries. Bulma will alert then when drones are in the area. Defeating the commander drones will reward Future Trunks and Future Gohan with Drone Parts which they can exchange for items to the male Researcher who they save from the first of these drones they encounter. The Researcher explains that they are state-of-the-art experimental Red Ribbon Army tech and as a result their parts are extremely valuable to researchers such as himself.
