How do you mount servos? Do you buy mounting brackets or make them yourself?
-
Double sided foam tape works great. But for more professional looking robots I sometimes use mounts from budgetrobotics.com
-
Zipties work well too.
-
Plexiglass. it helps that I have access to a milling machine. Drills and taps easy, looks great.
-
Use velcro or for a more permanent mount, screw them in to the material you're using.
-
I buy mounting brackets, my time is worth more than the time it would take to make them, plus I'd rather have a more professional looking robot.

I'm starting to think of using Sintra for brackets - as well as all my other robot parts .
I'll buy some Sintra in the next month or so and test it out

To bend a piece of Sintra®, you just boil it in water for 10 - 15 seconds (the length of boil determining how soft the material gets). After boiling, remove the piece with tongs (gently, so as not to leave an imprint of the tong in the piece), quickly bend it to your desired shape, and freeze it in shape with cold water. If you mess up, it's no problem -- keep your water boiling, and you can just repeat the process.
I assume that I can use molds as well.

My favourite solution is L shaped aluminium brackets. They are made to go on corners of kitchen units and stuff. Basically I just drill holes to match the servos on one edge and the same holes on the other then cut the pieces off.
I meant to do a tutorial on it but after cutting 36 servo brackets I havent needed any more doing just yet. As soon as I do I'll video the process. - this was when i realised how easy using alumium is, and its superb strength to weight ratio
Things like this can be really easy to do, its just a case of finding the right material and using a bit of imagination.
