The Waldo Units had Gappler Arms and Cutting Lasers with an empty Pilot's Cockpit ran by Artificial Intelligence Programs that replaced the need for someone to work the controls inside of the small device moving by Artificial Gravity Generators.

The Liir Construction Center began building more Waldo Units as the Mining Stations and Resource Processor Buildings started the hard task of providing the Resources to build the new Liir Colony.

The Waldo Construction Units looked more like a rectangular floating vehicle with one window in the Pilot's Cockpit and several tools on the sides of it while the back was used for storage like Semi-Trailers transporting supplies across the roads instead of the SCV Units that the Terrans used to mine with.

The only problem with the Waldo Units was that Electromagnetic Pulses disabled them long enough for enemies to hijack them and steal information on Liir Technology from the computers.

However when everyone in the Sword of the Stars Universe had started sharing technology and had their own Waldo Units working together, the Zuul and the Morrigi are the only ones at war with each other while everyone else was exploring the Universe.
