From-scratch build for wheel steering (hardware)
#21
Some much better photos and a longer video here:
https://drive.google.com/file/d/1wlPZNV5...sp=sharing

I thoroughly recommend this type of motor - as I said, it has a lot of torque, has a duty close to what's intended for an AP and its worm drive reduction is beautifully machined. As you can see I have it wrapped in Denso Tape so I can see it lasting a good long time. The photos show the belt off, on the sprockets but not in tension, in tension - and the latter two positions from the lever side.

if someday I could adapt my outboard motor it would make an incredibly powerful and efficient wheelpilot. I would use a smaller motor probably.

Sean you might find this interesting re solar powered boat.  https://kitchener.ctvnews.ca/mobile/vide...Id=1770652

Hi, newbie in reading mode
My idea is to use a couple of bearings: almost touching the belt while the motor is engaged (1), and when disengaged(2) protecting the motor to be engaged to the belt.
The motor has to slide between 1 and 2

The wheel pilots on ebay for $500 is too high.  That's basically what it costs new, and the motor is weaker than a wiper motor.

For anyone who hasn't seen Sean's wiper motor install:

Wow, wonderful!  Please, we need a video showing everything up close!  Smile

I tried to find such a thing on Ebay, but couldn't.  Can you provide a link to a motor like this?

I circumnavigated the South Island of New Zealand last southern hemisphere summer using this arrangement - very successfully. Super low power usage so no worries powering it from solar panels. So successful that it completely displaced my windvane self-steering into second place - even when more or less hove-to in 40 knot+ conditions in Cook Strait.


Cheers

I was also on the idea of installs an Electric Power assisted steering unit for its reliability and torque. Great to see someone did an endurance test, As I want to circumnavigate with the device. Another reasons why I am in favor is because the EPAS (or EPS) had an Planetary gear already fit into it. If it has a planetary gear, why do you still have the engage function? Does the planetary gear has too much resistance? Great video here: https://youtu.be/em1O8mz7sF0?t=335

Furthermore, Staying in the automotive scrap place, have you thought of the Electronic Clutches used in cars. Video here: https://youtu.be/RFC5jMhUm4s?t=39 . I'm not sure however if a the clutch has no play since it is designed to spin only 1 way. Using a electronic clutch, you would be allowed to fit it below deck. What are your thoughts on this?

Hi Ted,
Your idea of an automotive power steering motor won me over.
For my 13m / 10tons boat, we produced a Renault clio engine at 70 €.
After fitting it with a toothed pulley (autohelm 3000/4000 style), it uses the original pilot's toothed belt.
We tried it this last weekend on Sean's pypilot and everything went wonderfully after some groping on the gain settings.
It remains to try the gps and wind modes of tinypilot and to polish the finishes of the coupling.
During the tests, we noted currents of 4 Amp Max, which seems quite reasonable!
Thanks again for this idea
cordially


ps:for the pypilot plugin problem on opencpn 5.2.4, I recompiled the source file of Sean's github and everything works!

how waterproof do you think this motor is? Are you able to disengage it?
