Blog update part 10: link at end of this post.

So a busy few weeks CAD’ing up bits and 3D printing them off.

Had a go at the probe mesh, lol. The first print the holes were too close, this showed up when test squeezing it. Moved the holes a bit further apart and this time it printed much better and stronger. If you wanted to it could be crushed obviously, but even a firm’ish bump, wouldn’t break it.


The ‘utility arms’ have been printed, assembled (carbon fibre tubes where needed), primer painted and silver painted.


It was too cold here (UK) to be painting outside, so the rest of it was done in work, using their spray booth and heating



Did the same with the base and the eye units.




Drew up some covers for the openings in the bottom of the eye units.


Tested out the servos for the neck and the eye unit up/down motion and am really happy with the results.


Am happy with the centre of gravity, it’s just about right.



The best part though was the neck servo. I wanted to get a servo in to test it, weight of head etc. I had the eyes on etc. and plugged in the servo to my tester. It centred itself almost whipping the mast out of my grasp and took out three paint cans that were on the wooden bench in the background (with the cloth on) . I took a few seconds videos, which I’ll post up. There are thrust washer bearing’s and washer’s between the (silver) base plate and the 3D printed non painted part.

The only slight disappointment was the testing of the claw arm lift. Think I need to relook at how best to activate it. But apart from that little setback, am really happy with the progress. I have cut up some wood for the bottom of the base, and have been looking at the wheels, motors etc.
