Here, Now I'm going to show you how to make a 4 sservo robot arm. This robot arm uses linkage mechanism, controlling by arduino. This project started in May 2016 robot class. I've made the ai file of parts available for everyone to download for free. You'll need to adapt it to suit the file format of your particular laser cutter.
Step 1: Getting the Parts
To make this robot arm you need some parts:
-4 servo motors
-bolts & nuts
Step 2: Prepare the Base
I'd like to make the base part first, well without a strong base parts, robot cannot be strong.
Print the bottom parts. Combine servo motors with wood.
We have to print a ring which makes robot can spin around.
Step 3: Construct the Front Hand Side
Print the body and robot arm sketch using laser cutter.
Combine servo motor with body parts.
Step 4: Construct the Behind Hand Side
It's almost same with front hand side
Print the body and combine the body and robot arm
Step 5: Combine Front and Behind Hand With Base
It's easy ~ Just follow the picture then you can make it!
Step 6: Gripper
It's little bit complicated parts , so follow the pictures .
Step 7: Box
We need box to fix it ~
we'll combine base parts with it
Step 8: Code
I add the code file
f - front hand
d- behind hand
1 means first loop and 2 means second loop.
Step 9: Complete !!!!
Wow~ You made it !!
