The short answer ti your initial question is YES. Robbery comes in many flavors and does not require application of force or use of a weapon. Robbery is, in any of its forms, a very serious offense. You should stop posting information about this matter in a public website like this or anywhere else on the Internet, including social media like Facebook. You should instead be consulting with qualified criminal defense counsel immediately. Most of us here, myself included, will provide you with a no-cost consultation. Take advantage of that opportunity to speak privately and confidentially with suitable counsel.
Stop posting incriminating information on line and retain an experienced criminal defense attorney to represent you. This is a serious matter so if you cannot afford a private lawyer, at least apply for a public defender.
