Tools for Building Poppy

Is there a list of required tools for building Poppy?

Specifically, is a special crimping tool required for the wiring pins? If yes, please post a link where it can be purchased.

Please also note any additional special tools if a list is unavailable.

Important aspects indeed, some info were available on the old BOM list, yet it is good to remember them here:

Mechanical assembly:

  • Hex keys: 3 / 2.5 / 2 / 1.5 mm (take several 2 and 1.5 size because they are really quickly damaged)
  • Small screwdrivers with Phillips heads (M2 & M3 size)
  • Threadlockers (2 bottles for a whole Poppy humanoide)

Wire connection

  • A glue pistol is convenient to fix some wires where you want
  • If you want to create custom wires you will need a wire stripper, some Molex connector and terminals, and a small plier such as this one.

Also you can see on this picture (on the right) all the tools we have used the last time we built a Poppy humanoid:

Hi,

Thank you for the reply. I checked the Molex pins and they do need to be crimped. The photo seems to show a crimping tool on the right. Crimping tools can be costly. Can you provide a link where the appropriate tool may be purchased?

Thank you.

It is not a crimping tool, it is a (very useful) automatic wire stripper (20€)

Nice tool! However, it means the correct crimping tool still needs to be identified.

I would like to investigate this myself, however, when I click links in the BOM, they are broken.

I need to know what Molex connector is used then I can try to find the appropriate tool for the pins of that connector. This is the actual connector, (i.e. not just an example, but the one that should be used), right?

Assuming this is the required connector:

I believe this is the correct crimping tool for its terminals:

The price is ÂŁ190.26/$305.84 (Ouch!)

Please tell me if I am missing something…

Right

Personally I only use classic small pliers because crimping tools are way too expensive. It takes about 30-60s to crimp the terminal on the wire. Maybe it will take 3/4 attempts to learn how to do it correctly but buying a specific crimping tool is not really a relevant investment if you just need to create a dozen of custom wires.

The ones displayed on the picture do the job, here is one of of them.

I will build a new Poppy the next week, if you want I can take pictures of the step-by-step procedure to crimp a terminal on a wire ?

Thanks for the detailed reply. I agree the crimping tool is too expensive for only a dozen or so wires. I am sure we can improvise with small pliers or another way. Thanks for your offer to make a video, it is not necessary for us, but perhaps other people would appreciate it.
