Robronco was a Pre-War business that specialized in the market of robotics. They created numerous robot models including the Protectaponies and multi-limbed hovering robots. They probably had a hand in creating or mass producing the Sprite-Bots that continue to patrol the Equestrian Wasteland.
Littlepip encounters numerous robots throughout her journey, these include Protectaponies that had organic brains built into them. Robronco sold Robots all across Equestria and provided robots for the robot maintained Stable 24. Numerous robots have some form of energy weapon built into them.
In Project Horizons the company is owned and run by Mr Horse. He was involved in the projects run by the O.I.A and worked under Goldenblood. Robronco robots can be found throughout Hoofington, including an old academy were the robots were still working away. Ol' Hank was a sentient maintenance bot built by Robronco, he was overwritten when he heard Goldenbloods name and tried to kill Blackjack.
Robronco's CEO Horse also worked with Star Metal for a side-project, done as a favour to Goldenblood. They were also getting ready to make a line of Robots for commercial use, besides the Ultra Sentinels, like The Sweetie Bot. Horse also designed the self-replicating Mechasprite, which was sabotaged during it's display in front of the Ministry Mares.
In Broken Steel, Robronco's CEO Mr.Horse was aware of Krogoth's construction. Applejack was known to have spoken with him on numerous occasions and likely employed Robronco's expertise on robotics to make Krogoth a reality.
Project Horizons' version of Robronco is expanded upon, naming its ubiquitous CEO fully as Mr. Edwin Robert Horse and featuring him as indisputed lord and master of the titular city. Although he has never been seen by anypony in centuries except via a computer monitor, his appearance and voice are identical to the legendary Robronco founder, and he identifies himself as such. It is not known if this is the original Horse, a clone hiding behind a screen, or simply a computer simulation of some sort.

Victory-class Integrated Computrons - Big, blue, boxy, and balanced on one wheel, the VICs use clawlike appendages to grip and television screens built into their chests to communicate. They are known to take their orders directly from Edwin Robert Horse, but also have limited autonomous function to carry out mundane everyday tasks. VIC-20 is one example of this class.
Protectrons - Robronco's all-in-one security and protocol model, ponderous but dependable, with a pony-like conformation including synthetic nylon hair-plugs for mane and tail. A blue resin faceplate protects the configuration and memory access. Slimm-Two-None is one example of this class.
