Mounting brackets for SRF05 (Open letter to Jack / DAGU)

SRF05 is still IMHO the best low-cost distance sensor.

And there is still no good / smart / fancy / easy / pro / cheap way to mount the darn thing on a turning neck / servo / front..

We now have a good contact to DAGU from China who makes cheap and cool robot-stuff.

So.. I thought.. Why don't we make some suggestions to how we would like such a mounting thing(ey) shaped and made? And then ask Jack from DAGU if he could start producing it?

This was my idea.. and now I need your help and ideas towards the design :)

Yes! This is EXACTLY what I'm talking about. This is similar to what I did in my biped. The standard cheap R/C servos we mostly seem to use on LMR definitely needs a bearing on the opposite side as per Frits' working model.

What I propose is two versions of what Frits made: one identical to the above and another where the servos are rotated 90 degrees to one another in the x axis of his photo.

...or maybe just one which can be manually rotated in the middle.

This would form the joints in robot arms and legs, the joints between sections of caterpillars (or snakes), 2D pan/tilt heads. Armed with a fistfull of inexpensive servo couplings like these, there are no limits.


 Here's my version. It was a surprising pain in the ass to cut those holes out of aluminium accurately.

The drawing was borrowed from this awesome website.
Oh, cool site, cool work, skilled folks there! :D
Ya, absolutely not my work. It was Oddbot's!
The technical drawing are done using "Solid Works" by our talented engineer Gao.

Wham! Product has landed!


Telefox has suggested that a small servo could be mounted inside to tilt the bracket up/down. I will look into designing a second smaller bracket that will mount a minature servo inside for this purpose.

nearly 2 months ago Frits started this thread in hopes of a better sensor mounting bracket, after a few comments and some research by robologist I was asked to come up with a sketch or two. With more comments and more research by robologist we came up with a new product! Designed right here on this node.

Now where else can a group of people from all over the world come together and design a new product in their spare time and then have it go into mass production? Is LMR cool or what? Much thanks to Jack, Claudia and their engineer Gao for making this happen.

As soon as the brackets are printed they will be posted as LMR's first home grown component :D





Hey cool!

I would mount the sensor on "the inside", to make it more center over the axle. That would leave no room for a servo inside, I know, but it would look cooler over all.

Where can I buy some? Should we set up a shop, I wonder.. Anyone out there want to run a webshop?

Although most sensors won't care, some like the srf-08 and maxbotix EZ1 can only mount square and central on one side, pehaps we should sell them in pairs, one set mirror image to the other.
