According to the Internet Movie Database the Lost in Space episode War of the Robots came out on February   and credits Robby the Robot as a robotoid and William Bramley and Ollie OToole as uncredited robotoid voice actors A fansite Character Studies Analysis by Charles Mento claims Robot Robby knows the term Robotoid th Century Fox Home Entertainment describes the episode as The familys robot is seemingly replaced when Will repairs a robotoid from an advanced civilization  until the new machine wreaks havoc by trying to take over the ship   And in April  Marvel Comics released Avengers  which introduced The Robotoid  Obviously Beter didnt coin the term but I think all of these references should be listed as being notable
