K-9 Robot Dog

Ever since i was a young boy in 1984 and i saw Doctor Who on the local PBS station in Tulsa Oklahoma, and his trusty robot dog K-9. I have wanted one, fast forward 34 years, technology has finally developed to a point that this is becoming possible.

First I pulled some measured drawings off line, and I desired that a full scale one would be a little big for moving the project around with the vehicle i have, So I derided to scale him down to 80%. See picture of K-9 on front seat.

Using blue painters tape and cardboard to firm out the design,

using 1/4" PVC foam board grey and black. Also found a soft vinyl flood light ring, I had in a parts bin. to clean up the neck hole.

used laser cutter an this file to make side K-9
