Update: the castor stl file was the wrong scale It was 10X the right size. I reuploaded it on Sep ,12,2019. Sorry for any inconvenience.
This is my design of a half scale Robie Junior. The Robie Junior was a robot toy sold by Radio Shack in the 80s. The original had remote controlled and autonomous modes. Mine is only remote controlled. This is not an exact copy. I designed it around an 80 MM clear Christmas tree ornament available on Ebay, but I got mine at Hobby Lobby. I designed it so I wouldn't have to cut on the clear globe. It doesn't have the front bumper switch or the switches in the arms. It also doesn't talk like the original. The two N20 gerarmotors are controlled by an Arduino Pro Mini driving an L9110S H bridge module. The gearmotors could be 60 or 100 RPM. It has a TSOP4838 IR receiver in the dome to receive signals from a universal remote sending Sony 12 bit VCR codes. It can also be controlled by the Attiny85 based remote I built for another project.
