14.75" tall (22.5" tall to top of wire antenna) made in Japan by Masudaya (Modern-Toys) in 1957. This is the second known radio-controlled toy and the first known remote-control robot. The Radicon Robot is also the first of the famous "Gang Of Five" classic Japanese robots. The robot was technically difficult to produce due to the complex mechanism and the thicker tin plate used to stamp the parts for it. The outside surface of this tinplate has a special textured paint that was electrically-applied. The robot is controlled by 3x7.25x2.25" deep remote (complete w/15" long antenna) that is battery-operated, as is the robot itself. Left side of the robot's head has separate wire antenna to receive commands given via remote. Both antennas are original as issued. Comes w/photocopy of the instruction sheet. When all batteries are in place in both remote and robot and robot's "Off-On" switch is turned on robot begins working and functions include - moves forward, arms swing, loud clicking noise is produced, both antennas on head turn and occasionally changes direction. This action (changing direction) as well as stopping and starting is supposed to be controlled by using the remote, but all but stopping and starting works on its own. Also working is the light in chest compartment as well as blinking eyes. Both remote and robot are in high grade condition. Both battery boxes are spotless. Remote has a few lt. scratches on lid, a few minor paint nicks on sides. VF/Exc. Robot is free of defects w/exception of a few small 1/8" paint nicks on edge of battery box lid, o/w Exc. An overall much above average example of this iconic robot, widely considered to be the Holy Grail of robot collecting.
