Robbins was arrested Sunday at the San Ysidro Port of Entry after authorities doing a background check upon his return from Mexico spotted a warrant from the San Diego County Sheriff's Department.
Robbins was best known for his performance as the voice of Charlie Brown on "A Charlie Brown Christmas" and "It's the Great Pumpkin, Charlie Brown."
Defense Attorney Marc S. Kohnen told the judge the bail was set too high for a man with no prior criminal record, who has lived in San Diego County for 30 years and whose work is watched by so many children to this day. He called him a "distraught man" and said "this is not a stalking case" but declined to comment on what led to his arrest.
"Mr. Robbins is an eccentric individual," Kohnen told reporters after the arraignment. "He's not a threat to society."
If convicted, he would face a maximum sentence of up to nine years in prison, prosecutors said.
