An interesting little mobile robot is beginning to emerge. There are several methods for increasing the force of the closing grippers, such as a screw thread between the jaws, scissors can work if the pivot point is placed correctly, plus adding rubber or other non slip surfaces to the jaws also helps.

You can reduce the gripper jittering about by slowing down the speed at which it moves by inserting one ofr more way-points with small delays between them.

You could try an alternative approach of using two counter-rotating brushes to sweep up the objects, much the same as road sweepers. You would then have the problem of getting the dirt into the bin somehow, but the sweeping approach does work quite well.

Hi,

I really like what you have done and it is in good scientific protocol to show the weakness as well as the strength. If there is any chance that the force that opens the clamp has enough strength you could add a little counter tension with a spring or small rubber band. Then when the clamp closes it will have that additional force to help it grab on. Also you could add some rubber surface tape to the clamps to give them additional friction. Great project.

Nice try, but your whole set up will only work for light weight objects.
