An alien robot comes to Earth and determines that part of his plan here involves geting set up with a lot of cash in as short a time span as possible. He has a number of physical and mental attributes exceeding that of the average human to assist him with this; namely:
As a non-fleshbag, he does not feel pain, bleed, need to eat, and so on. He does need a certain amount of oxygen, although very little, and "sleeps" in roughly human-like cycles to recharge.
He is more or less indestructible and will quickly heal from most wounds, excluding severe bodily trauma (e.g. losing a limb).
He has peak-human strength and speed, and superhuman reflexes. His senses of sight, sound, and smell are also superhuman, but not to the degree that they would no longer be grounded in reality.
His robotic brain functions on a level basically equal to that of a supercomputer; he has a perfect memory and is able to instantly process even highly complex information. This also allows him to read and learn very quickly, as he only needs to so much as look at a page in a book to fully understand it.
As one would expect from these capacities, he has educated himself extensively on humans and human culture. He can be assumed to have memorized all of our publicly-accessible history and possesses an encyclopedic knowledge of the world.
This also extends to knowledge of psychology, making him a very skilled people person. He has no supernatural powers of persuasion, but having memorized everything we have to offer about how our brains work brings him pretty close.
He looks and acts perfectly human, and would only risk discovery by allowing somebody to observe his inorganic functions (such as his lack of blood). He would prefer to keep a low profile and especially avoid government scrutiny, so anything overtly illegal is a bad idea. He is a more than capable fighter thanks to having memorized vast quantities of relevant information, on top of his physical capabilities. However, he would prefer to avoid having to kill or fight very many people, due to the attention that kind of thing tends to bring.
I imagine that his best bet in accomplishing this would be putting his supercomputer mind to use in some kind of large-scale financial maneuvering, but I'm not really sure what specifically he'd be able to do. Any input would be much appreciated.
Edited for extra details: He can choose where he ends up on Earth, but it likely doesn't matter too much. Even if he's not able to procure transportation, he can really just walk or swim to wherever he needs to go. He doesn't have a legal identity, on account of not being born on Earth, but probably wouldn't struggle too much with obtaining one by going through the standard processes as a John Doe or immigrant.
To expound on his self-imposed restrictions, he is not significantly opposed to illegal or arguably immoral means. However, as a general rule of thumb, any legal method is better than an illegal equivalent, and possibly better than even an otherwise superior illegal equivalent. This is for no other reason than to minimize attention; if he was completely certain nobody would ever realize the crime had been committed, then it wouldn't matter, but that's rarely a safe bet to make. He doesn't have a real problem with screwing people over or even killing them/otherwise bringing about their demise, but this is generally to be avoided for similar reasons. Also, all things considered equal, it's better not to eliminate potential future resources, even if there isn't an immediately useful connection in place.
