I wanted to start a new thread to avoid hijacking James micro SES thread.
I have been designing this custom gripper that’s a little more compact as a solution for the micro ses series brackets. This gripper utilizes the standard ses bolt pattern, so it could be used with any ses bracket series if desired.
The general idea is to have three lexan layers of the outer main frame (chassis) giving the gripper two internal fingers. So the assembly would be frame, fingers, frame, fingers, frame. Plastic standoffs or plastic washers would provide the gap needed for the fingers to move freely between the layers. The design is also stackable, meaning you can add as many additional fingers as needed anywhere from 2 layers (frame finger frame) or 5 layers (5 frames with fingers in between). You also have the option to skip fingers between the layers to position a “thumb” in the middle or to either side. Each finger has two holes to attach the gear finger to all the other fingers using standoffs or plastic washers and screws. Rubber tubes could be used to cover the fingers providing added gripping ability.
Below is some pictures of the open and closed range of these grippers.
I was thinking that a push rod would be used. The fore arm would have the micro servos shaft in the x plane and mounted to the grippers wrist ses bolt pattern. I’m not sure really how the servo would mount, I would have to try a few things to see how it would work.
Do you have any suggestions? how would you go about attaching this to fore arm? Would a push rod be sufficient? I would love some input on this.
i know im new to all of this but you have gave me so much info i thought
id give you an idea so here gose
what if you used a small dc motor and a long worm gear on the push rod
sorta like a make shift linear actuator or rack n pinion steering
sorry ima automotive tech
maybe
thank you robot dude but he would still have to work on how to mount such a thing im working on more ideas an ill try to put the one above in
to a drawing or a picture
thanks again
I see the worm gear on the push rod but I don’t think that will cause any push pull action. Usually worm gears are stationary and a ball slider that works like a nut, does the linear motion. A rack and pinion would work.
Using small dc motors and gears would certainly make a very compact design, however, I’m looking for something a little less complex and can be easily attached.
yea its was a bad drawing and i was at lunch an in a hurry i put the worm gear on the wrong part and your rite now that i think about it a worm gear is not the rite way to go
i will do a better one after work and post it so you can have a better idea of what i got in mind more of a rack pinion style set up
time to dig out my auto cad software where ever i put that
but you might be rite sometimes simple is better
