When testing the leg ultrasound sensor i am not getting the same results as mentioned in the build instructions. They state to start 2m away from a solid object (in my case i am using a wall). I start at the stated 2m, all good no blue light. At 1.3m the blue light comes on, at 200-300mm the light goes off again. This is the same for both legs, and also a 3rd sensor i have (i was sent an extra copy last month).

Surely this can not be 3 duff sensors if they are all doing exactly the same thing.

I notice there is 2 adjustable resistors on the sensor board, perhapse these are not set up correctly to set the sensitivity of the ultrasonics? Although that is jumping the gun as i dont know what they are for.

Please dont just give the standard order new parts line. If parts were faulty surely i cant have such bad luck that 3 dont work, unless the actual sensor board is faulty, but everything else works as it should, so hard to believe.

I would not read to much into it if the parts are not doing as the stage instructions say then there faulty and purely just that.

Personally I would not mess with anything and doing so could void the warranty on the part as it would no longer be as supplied.

The best thing to do is reorder new parts my sensors are working fine on the official build.

Yes i would totally agree with you there. We are both facing the EXACT same issue. It would be impossible surely for us both having the same results and both having 5 faulty sensors between us. Does seem sus, this needs to be looked into by a technician. I have a gut feeling that when everyone gets issue 53 next week they will all be here asking!

Ok is there any chance you can get a video sent to us with your test results?

To quote the instructions it says:-

Ensure nothing is directly within 2m of the shoulder sensor. Then hold up a solid object and move it towards the sensor.

Are you using the piece of wood as shown as it is a way of testing the sensor with low power from the battery test box. Its a simple low powered test to check the sensor reacts in a certain way ,hence the use of the wooden stick.

If the sensors do not react as they say in the instructions then get a replacement.

Have you followed the stage three instructions and used a stick as asked to do the test

Using the binder to carry out the test gives the correct results as the instructions ask for so the sensors are working correctly.

Again this is a low power test using the test box.

Asking the sensor to react to a wall on low power is simple asking it to do too much for the power available.

but again, starting the binder at 2m, and moving it towards as the instructions say to the light comes on at 1.3m. the same as moving towards a wall. so what is correct? move an object towards it, or wave an object at 500mm distance?

the instructions say to do 1 thing, the de agostini video shows a different thing (basically just waving an object in front at 500mm). this is where im super confused.

following 1 set of instructions i have a problem. following the other set i dont, so which is correct? as if im confused (and i build jet engines for a job that are far more complicated than this) im pretty sure there will be many more out there feeling the same way. and not everyone has access to here, or youtube so are relying on the magazine.

yeah, there's certainly some confusion somewhere.

up to date i have followed all build instructions religiously. if i have been unsure of something or had an issue i them come here and check the build diary, which usually clarifies things up, and to date the only issue was with screws early on when the mag said 1 size and the build diary said a different size, that was quickly clarified. the other issue was what everyone had with the projector only showing 1 vid, when it turned out that since the mag went to print the hardware had been changed.

so we havent had the best run of clear instructions through the whole build. its still confusing with the screws, sometimes it gives a size in the instructions, but none of the screws are marked up, sometimes its jsut use the black screws for eg (we have several) or others its just said use the screws supplied last time. but i think im muddling through pretty well so far. dont get me wrong, im absoluetly loving it, and challenges like this are what make it fun for me. im not trying to cause arguments, or slate anything or anyone. i have been collecting things from de agostini since i was 4 years old! (and other too over the years). some of you guys may recognize me from the rb7 that i built last year, even that was easier to follow foe screws and fixings etc. so im a bit lost with why the screws are so mixed up on this one. hey ho, im sure we will get to the bottom of this in the end. currently i firmly believe its and instructional error and that my parts are perfectly fine.

That would be amazing :-) because currently the way its testing my poor droid will not move in my house hehe.
