Let's Make Robots!

My First Robotic Arm

Pick & Place

Hi there !

I am a new member here.

This is my first Robotic Arm that I built myself.

Most of the parts are made out of acrylic plastic.

I use a micro servo for the gripper,

a std servo for the elbow, two std servo

for the shoulder and a stepper motor for

the base.

 

«THE GRIPPER»

Motion of the robotic arm not so smooth , I want to make it move smoothly , but the space is not enough for my code.

If there are an expert that very familiar with basic stamp programming , I need some advice!

 

I feel very happy that I built my own Robotic Arm and also I become a member of

letsmakerobots(a place that full with robot builder's )

Hi there - I have to say that I glue my pivot points direct to the servo, I can then either use them or not as I choose. all it means is that you have a small screw sticking out of the back as in the picture.

 

You can use custom made mounts which fit round your servo and essentially do teh same thing, but these cost almost as much as a servo I don't tend to bother. I often tend to buy used servos from Ebay which means I don't worry so much about breaking them so much. You can make your own servo brackets with a bit of effort - take a look at Lynxmotion's site, then make your own - that's what I've done a few times !

Hi there in response to your question - I have to say I've permanently fixed the pivot points - i find it useful to have them there on so many issues, and you don't have to use them.

If you want to do a temporary solution, you could try using "polymorph" (without which no genuine robot builder will be happy) - this is a hard plastic that turns like putty at about 60 degrees C and liquid at 80 - I find it's quite handy  for sticking things and will come off with a bit of help from my wife's hairdryer.  You can get it on Ebay and it's brilliant for all sorts of things ( I know I sound like an advert but I'm not connected with them jsut really like the product)

I did experiment making a simple bracket for the pivot made out of a strip of thin aluminium, which went under the servo and up each side being secured under the fixing screws. It worked OK but was a bit of a hassle to produce, so I went for the easy option and reached for a tube of araldite and glued it on.

Hi Bro,

Last month I bought polymorph on ebay for my new project. I prefer  polymorph more than other , because it can let you make any shape you like .

Ya, araldite is more secured.
