Item is as described, good info and documentation with the package and in the link provided including stl file, arduino sketch, assembly instruction, operation instructions, wifi details. As for hardware, besides what is seen in the pics you get a charging cable, data usb cable (for the nodemcu that serve as the brain), screws and servo horns for everything, and a battery but that is marked as a gift. The robot's firmware is customizable.
finally I got the articles. very slow delivery, it took 1,5 months longer than initially estimated. there were also no exact information avalable about the delivery. after contacting the seller, i got only the answer, that if the maximum delivery time is expired, i can open a dispute case. not really a customer friendly answer.
