Onshape Project - Robot Gripper - Step 7 - Assemble the Gripper Using Mates

[@david_manfredini]

That was a great course to understand the basics of Onshape. Thanks !

where are the connector pins???

your wayyyyyyyyyy better than my teachers

Halo, at the 3:42 mark of your video, I noticed that you were able to freely swing around that swingarm. For some reason I'm unable to do that as if it's completely fastened. I know I used the revolute mate, do you know what's the cause?

[@zen_end2]

Figured it out, I didnt fix the base.

Glad it helped

Thank you so much! I’m learning so much

I am really enjoying this, thank you, but at around 9:50 I get the same thing with revolute mate, the blue arm flies out to the new revolute mate but when I hit "solve" the bottom one flies out to - I have tried this about 40 times now and I can not get them to play nice - anyone have any tips? Thanks!

[@SamZhang-qg6gb]

you have to click the revolute mate on the red thing first then click the revolute mate thing on the blue thing; not the other way around. idk why the order matters but I had the same problem when I did blue part then red part so I changed it up and it worked for me

My mating on the link between the actuator and the middle hole of the gripper give me an error. I've gone back to the previous tutorials and my dimensions are good. Great video, please help.

Check the constraints that show up in red. Try deleting one at a time and see if it fixes it. If that doesn't work, start over.

when I unsuppressed revolute 2 the replicated parts just disappear with an error :(

[@Onshape.Learning.Projects]

Yes, some update in the Onshape program has caused this to stop working. A similar workaround would be to create a new assembly, this would be a sub-assemble of the gripper and one set of attached swing arms. After attaching one one swing arm with a revolute mate, use replicate to place the second arm on the top surface as shown in the video. Use the linear pattern tool to place the two lower swing arms like in the video. When done, this sub-assemble can be placed in the top assemble with the base and continue to assemble.
