This blog deals with how an amateur like me made a stupid gripper that works perfectly only in opening n closing but unable to lift any appreciable wt.(applicable for the earlier versions).We have also discussed here of making another gripper that I’m using now in my now working project of a flood transporter.

Well starting with ,lets leap back from where I started. I was checking on many youtube videos n googled also of how to make an efficient gripper… bt got void in my hands as I surfed more … cause I donn  have of much of resources.. moreover most of em were using servos bt, alas!... I donn have a servo controller(2000 bucks here if I have to gt it online).

So same painful story ..I brought a toy dozer from market (Which in most of my projects serve as the “ore”). operated it up

Broke a old photograph frame(Plastic board source)

Took some gears from my odds n ends box.(keeping in mind the gear ratio required for my experimental project).

Put them together

N here they are 

Well here are some other ideas of making a gripper out of scraps like say for e.g. old cd drive

Jus open it up n see how it looks like put ur imagination into work

Think hard & make it work…. Pls Let me know when u did that…

Well moving on…..

This is the gripper that I am working on for a project at IIT kharagpur..(It’s a flood transporter , manually controlled) .

As you can see(well dat’s not a clear picture,I agree,, sorry frns not having a digicam)..inspite of gears I hv used levers.. these r better for my purpose here..as they can apply more force to the other member of the gripper claw at it’s vertex, n can move it more efficiently even when tangential force is acting, when the gripper is inclined to pick up things….

Inspite of the gear box ..it would be better if we can use a servo & a pot at the centre calibrated in such a way dat it can make suitable changes (control the servos degree of rotation)according to the programme written on our developement board … for a really controlled gripper…

Uptill dis folks for now…

Ne confusion abt this…
