Can a jury be instructed that specific intent is an essential element of the crime of robbery?

No other instructions in respect to intent were given or requested. The court's failure to instruct the jury that specific intent is an essential element of the crime of robbery was clearly erroneous. People v. Sanchez, 35 Cal.2d 522, 526-528, 219 P.2d 9. However, upon examination of the entire record it appears that the error was not prejudicial. No other verdict than a guilty verdict was probable had the jury been properly instructed on specific intent.
