4 Large Claws to put heavy and large sections of walls or buildings up. 

3 Medium Claws to support the building as the welding parts keep it together

6 Smaller Claws for more precise positioning

4 Welding Lasers with the ability to drill through around 50 feet of dense metal. It's mainly used to weld stuff together in building projects but can also be used as a weapon of last resort. 

4 rotating tank tires that can be adjusted to go up and down landscape relatively quickly while keeping ahold of the ground. 

Enough storage to keep around 4 50 ton walls in the cargo section on the back. 

92 micro processors for all the different algorithms 

The Construction Bot is a relatively large and powerful vehicle that requires 4-5 large power cells to function with a running battery of around 4 days. Its main objective is to build but can also be used as a mining bot if needed to. Once its task is finished it will return to its charging station which is where it will stay until further instructions are given. They can also be used as a defense if everything else is disabled. It cannot take flight but it is mainly used in space, therefore, it is considered a 'Spaceship'. The ones on habitable planets are less powerful due to not needing as much energy nor as much fuel. Due to how large Scelfor IV they have been modified with more batters to make the long distances and build what they need and then ferry back. When a 'pack' of these bots are sent it can finish a base in around 2 trips to the site putting everything up from the oxygen holders right down to the launch pads. The weight of one of these on  Scelfor IV which has a gravity of 92.9 is around 90 thousand tons. it can also be modified to carry fuel or serve as an energy 'base'. it requires no crew to use but a human does need to monitor it from the base it was sent from. There are 15 of these per base.
