Sruggling with Soft Air gripper. Only the two legs clode to the air tube blow up. How much air is needed to blow up the big air gripper?

Hi Mileyengela,

I'm sorry your question went unanswered for so long. For future reference robotics questions are better located in the Physical Sciences forum and not the Life, Earth, and Social Sciences forum.

These robots can be finicky and take some practice to get them to work. A couple suggestions:

Try using a large syringe like this instead of a squeeze bulb, it may be able to pump more air: https://www.amazon.com/Buorsa-Pack-Gard ... 074LV27LD/ (you may need to purchase additional tubing to adapt to the syringe tip)

Try partially wrapping the legs that are already inflating in rubber bands or tape. This will make it more difficult for them to inflate, and will help direct more air to the other legs. After a leg inflates once, the material gets stretched and becomes easier to inflate the next time (kind of like pre-stretching a balloon), so it can be difficult to get the other legs to inflate after this happens.

Hope that helps!

Thanks,

Ben
