Autonomous Portable Power Unit

## Basic Description

The Autonomous Portable Power Unit (APPU) is a form of artificially intelligent robot fitted with advanced power generation systems for the purpose of distributing power in times when it is needed. They are designed to be able to operate independently, and their triad of universal sockets and cables allow for all sorts of machinery to be plugged into them. While they are relatively basic contraptions, these specialised units can prove a vital role in times of need, and are primarily used by engineering, construction and logistics staff - though have seen usage in other areas too, including the medical and even military sectors.

## Advanced Information

### Intelligence & Sensors

In terms of its artificial intelligence, the APPU is relatively basic. Despite the fact that it is capable of interpreting the full extent of human language, with subsystems permitting it to understand even the more advanced sections of said spoken language - including sarcasm and humour - though it, in itself, is not quite capable of emotion, independent thought and so on, nor is it capable of speaking (though it can relay spoken messages, and also record them). It uses a variety of basic sensory equipment in order to complete its duties, including thermal, gravitational, magnetic, optical and motion sensors, with additional abilities including detecting radiation and biological/chemical contamination in the air.

### Anatomy

The APPU follows an incredibly basic, bevelled cuboid shape, with various ports on its front and back to allow for cables to be plugged in and for the unit to be interfaced with. It is also bipedal, featuring two small, stubby legs underneath itself that allow for it to move at a relatively slow pace (up to 3km/h), but also provide relatively good stability - and in the case that it does topple over, movable counterweights fitted into the machine allow for it to tilt itself back onto its feet, which can then electromagnetically lock themselves to the ground. APPUs stand at 1.1m (3' 7") in height, and weigh approximately 32kg (70lbs), with their carapace being constructed from cheap low-density aviation aluminium to allow a basic level of protection - although it often won't stop bullets (however they have a better resistance towards heat-based weaponry due to their heat-resistant coating and insulated internals). On both their front and there back, there are access panels which feature a variety of electronics, including several universal ports to allow them to be plugged in, a visual interface panel (only on the front port), and various switches to configure the unit and control power flow. There is also a small filtered heat vent on the back, directly below the panel, which allows it to vent hot air from within itself. The heat produced by this isn't quite capable of being more than a major inconvenience, and the integrated filter prevents backflow of gases and fluids, ensuring a total seal (which also makes it waterproof and capable of operating on space). It can be noted that the APPU is vacuum-rated.

### Power Generation

Internally, there are also several different power generation systems. Depending on variant, they can feature a variety of different generators within themselves, though default variants feature a multipurpose chemical generators (which is capable of accepting petrol, gasoline and other similar chemical-based gases), a biological matter recycler (which allows for biological matter to be recycled into power) and a lithium-tungsten battery port. However, other variants feature more specialised equipment, such as integrated fusion and fission reactors, diesel-based generators, and battery ports for other forms of power cells. When run only by their lithium-tungsten power cells, they produce 250 watt-hours of power, which can be bumped up beyond 1100 watt-hours using other systems, especially with fusion generators. They also feature universal battery charging ports for all sizes of batteries, which allow for all IEC-compliant batteries to be slotted in and recharged, ranging from 3LR12 batteries to LR44 batteries in size, and even smaller. All of these can be accessed by opening the lockable & sealable hatch located on top of the unit.

### Storage & Modularity

Some variants can also be purchased with internal storage units of varying sizes, which, combined with the incredibly powerful leg servos of the robot, allow for it to carry up to 22 tons in weight before servos fail, and the unit can no longer operate under the weight it is subjected to. Some power generation systems can also be swapped out for additional storage on top of what is fitted to the unit by default, or the external baggage clamps fitted to the sides can be used to fit various forms of baggage, such as ALICE packs, travel packs, suitcases, and other forms of bags. The APPU is also highly modular, with its basic design allowing for consumers to modify them with little effort, and the universal components included inside allow for it to have internal components entirely replaced, added upon or altered with ease. Additional factory-issue components are also available for purchase, and the high software compatibility allow for entirely new segments of software to be uploaded into it, which can also allow for one to become sentient, if one wishes for such to be the case.

## OOC Notes

As long as one can comprehend and understand how the APPU functions, it is allowed to be freely roleplayed. The APPU is an incredibly basic robot, and, as such, should not be treated as a military machine that can take bullets like a tank. Its armour isn't thick enough to stop a bullet, with the exception of low-calibre rounds and hollow-point rounds, such as .22 LR, 9mm hollow point, .45 ACP hollow point, and so on and so forth. Please note that even a hard enough punch can leave a dent.
