Hello everyone,
I just bought a Arduino Braccio Robot Arm, but I'm having difficulty assembling the kit. From the instruction, I'm struggling with this step
When I put the screws in place and try to tighten, nothing happens the screw doesn't tighten. I feel like screws lengths which is 6 mm is too short. Anyone experienced this issue? I was thinking of buying screws with same diameter but with 7-8mm lengths instead. But I'm open to any suggestions.
Thank you
I don't know anything about that kit, but I wouldn't recommend getting longer screws. I would figure out what is wrong with the assembly that is causing the problem, since I would assume the screws are the correct size.
The plate you are trying to fix is not symmetric, it fits correctly only in one position.
Make sure the concave side points away from the arm.
Hello so I fixed that issue but I've ran into another assembling issue. For this step
The part they sent me is missing a screw hole
That's not too bad but the problem is I can't fit the motor through the hole, it's really tight and the motor gets stuck
So I don't know if they also made a mistake with the dimensions, in the video tutorial it seemed so easy to fit through
I fixed that but not I'm having another assembling issue...
How was the issue (screw not reaching nut) fixed?
I am sure you are anxious to get this working, but accuracy is more important than speed.
There are five (?) servos to be mounted. The engineers determined a nut (where indicated) would not work (maybe it impeded movement of another part). Are you using the correct part? The parts count in your instructions will identify every part.
Are you using the correct motor?
Clearly assembly instructions present different adapter from yours. They likely modified it to be compatible with different servos. If it prevents the servo to be mounted and work correctly, I suggest you to return the kit.
I reversed the motor side to fit into the part, and it fits perfectly. But the issue is that it doesn't match the instruction manual
I think they messed up my kit
It's not the same part (or it's upsidedown). Have a look at the other servo mounts.
The only difference between your image and the official video at 9:43 (steps 16 through 18) is the one screw hole.
Insert the motor correctly.
nope mine is mirror the other way, I can't insert it the other way, it gets stuck
it is the same part, but the one they sent me is missing a screw hole.
For step 17, I tried mounting the motor based on the manual but the motor cannot fit that way. it fits if I flip the motor the other way. I honestly think Arduino messed up.
use the 3 mm × 6 mm self-tapping screws (usually silver or black).
If the screws are M3 machine screws instead of self-tapping, they will NOT grip.
Check the tip of the screw:
If it’s sharp, it’s self-tapping (correct).
If it’s flat, it’s a machine screw (wrong)
If keep spinning with 6mm screw use 8mm because some kit shop wrong screw
Okay... so you have a part that was formed in a factory, yet completely opposite the part that everyone else gets. Good luck.
orly.
its not the screws, I don't know how but I can't fit the motor 6 into the hole in the direction the lab manual says, its so tight and it gets stuck
This is the furthest I can fit it.
The 3mmx6mm screws don't even touch the screw hole. I don't know how the person in the video fit it through so easily. I feel like the hole is just too small, I don't know does Arduino have the STL file I can use to edit the hole to make it bigger?
Dude I literally cannot fit the motor in the way the manual shows, the motor is stuck and the screws don't even reach the screw hole
