What is the definition of robbery and what is the force required to make the crime a robbery?

"'Robbery is the taking of "personal property in the possession of another against the will and from the person or immediate presence of that person accomplished by means of force or fear and with the specific intent permanently to deprive such person of such property." [Citation.]' [Citations.]" (People v. Clark (2011) 52 Cal.4th 856, 943; see 211.) "'"[A]ll the force that is required to make the offense a robbery is such force as is actually sufficient to overcome the victim's resistance ...."' [Citations.]" (People v. Burns (2009) 172 Cal.App.4th 1251, 1259.) "'If the other elements are satisfied, the crime of robbery is complete without regard to the value of the property taken.' [Citation.]" (People v. Clark, supra, 52 Cal.4th at p. 943.)
