Testing the servo movement of my model. I will make the shell tomorrow and if I have time may back light the meters. This was supposed to be just an appearance model but I was eager to get it going so I wont feel too bad if all the features cannot be implemented yet. Now comes the graft of collating research, idea generation and design development together, and communicating the concept… I may back light the meters if I have time.

Got the pieces for the chassis laser cut and part assembled. Despite the no-drilling assembly so far, I still have some fiddly holes to drill with very tight tolerances (can’t believe how small I made this thing!) so although I am excited to see something materialise from a 3D CAD model, I press on with trepidation.

Love these tiny machine screws.

Another day of 3D work, and thankfully, it is now finished. I think being up-close and personal to my product in Rhino 3D has distorted my sense of scale – I ended up using 1.6mm machine screws to assemble my product. Tiny, but, like an intricate piece of jewellery it is a thing to be respected, and hopefully listened to! Been experimenting with producing different tones out of vibration motors using Arduino’s PWM output and the Adafruit Motor Shield. It got me thinking, it would be quite fun to make a simple robot mouth with one in the future, watch this space.

Meanwhile, here’s some inspirational design language.
