Big bit of aluminium, carried home very slowly on a bicycle



Notice the pieces on the right are curved to create the taper on the robot's body



After folding



Sections of bar to make Ralph's feet



An inefficient way of cutting lumps of aluminium - must get a power hacksaw



Drilling a foot on the lathe



Completed feet



The robot 'necks' are made of offcuts of Corian, a kind of plastic used for kitchen surfaces



Cutting the grooves for the two domes that make up Ralph's head



Completed necks



Other parts (each robot needs two hands, wrists, shoulders, and thighs)



Completed hands



Metalwork painted, just have to trim 66 potentiometers...



A 'Weird Sound Generator' PCB from musicfromouterspace.com



Work in progress



I only really had to make one robot, and then it made the others all on its own...



Wiring made easy with photocopied diagrams and a highlighter to colour completed connections



Notice the useful sliding drawer compartment for the 9V battery



The pink one is called Ralphette






After finishing making these I discovered there were in fact other Ralph the Robots, including this slightly scary one.

He has lights behind his tie and his hat vibrates, but he sadly can't move his mouth.
