Inmoov's New Gripper

 
#1

I found a design for a robotic gripper on Instructables, so I thought I would make one for my InMoov. The basic design was done by Techiebot here's the link to it;

I had to design and print a few parts to adapt everything to fit into the arm of my robot. It will pick up small objects and with a little more suction the gripper could pickup bigger objects.
The EZ-Robot OS sure makes it easy to animated things like this but I don't need to tell you all that.

The first video shows it working and the second one describes the build.

That's really cool. I have been looking at these balloon grippers for a while, but I never would have thought you could use a servo to create suction. Very clever.

Nice work Bob.... Really nice!... Did you just print a new forearm and wrist and swat out your inmoov's original arm?

Never mind just re-read your post... Actually that's not a bad idea... swappable arms... Smile

That is a great piece of engineering effort ! Really works well, especially with smaller objects.

Nice work Bob! I've also wanted to try building one of those types of grippers but just never had the time. Sweet implementation!

#6

Great idea Bob, very inspiring.
Your Inmoov looks and moves so naturally.

Thanks for your comments.
I printed a new forearm so I can swap it out for the original one. I find that the HS- 755 servo has lots of power to pull the syringe.
This was an interesting experiment, I think I'm going to try a small pump for the next version, to create more vacuum, then the gripper can be larger. The problem is finding a membrane that is the right size.

COOL!

It,s cool but i was turned off by the look, it gives the robot a "nubby" lts better fit for a desktop arm instead of inmoov's.

I agree it looks a little odd! It was a proof of concept and a challenge to see if I could fit the mechanism in the forearm of the robot.
