VEX robotics and 3D printing ... And new goodies!

File

At my school I have a group of year 9 students building a VEX robot... An extra curricular after school club.

In a fit of madness we decided to not build the standard "protobot" and do a hybrid "clawbot/protobot". All very well but part way into the build someone noticed that we don't have the claw in our kit... Beginners mistake!

So, being a bit brave about it I said to the students that I would search the web and see if I can download the 3D CAD files so that we could print the necessary files.... And I found them!

Talk about a steep learning curve... I fired up Autodesk Inventor (I usually use Creo!) opened the .step file and exported the parts as .stl (then discovered that I could have used Creo anyway!.... Dohh)

So now they were printable files. Most of them are a bit challenging as they need support material, but with Axon 3 (alpha) the support generation looks to be superb, so I was up for the challenge.... And the photos show the results.

Having so much fun I printed most of the parts... I'll have to leave a few for the students to do in school. I don't think the PLA plates will be strong enough, maybe a bit of a redesign for these, but that's an extra project for the students to do :)

There can't be many clawbots out there with printed claws, maybe this is a first ... If it works! I'll post some more photos later (if we are successful of course).

Oh, nearly forgot about the new goodies mentioned in the title of this post.... I have just received (and fitted) a new bed and waste bin (commonly known at BfB as a snot box) and a new wiper (snot flicker?) to my 3D Touch.... Wonderful!.... I'll post some more info about these later.
