3D printable robotic arm
Description
Technically mk3 of internal development, but for y'all it will be mk1.
Feel free to remix/change as there are some things that are a bit iffy in relation to weight management and gripping things but other than that it works well.
This is less of a utility robotic arm but rather a more "fun" one.
Printed with ESun PLA orange
This only contains stuff for the robotic arm, no rover, as that is a WIP(and will be for a while as I've taken a break).
Components:
6 MG995 style servo motor (other versions work too, also for my build I specifically used 5x 180 MG995 and a 360 free spin MG995 for the base)
Lots of M4 screws and nuts of varying length, (Bare minimum: 4 each per motor and 10 for the claw mechanism)
The small screws included with the servo motor (3 per motor)
A microcontroller or something to control the servos. (Personally, I used an Arduino Uno)
(HC05 Bluetooth module if you want)
3D printing parts included in the .txt file
Assembly tip:
Build upwards, not in parts, as it will be painful to assemble later. Also, be wary that the support arms not connected to the servo motors should be connected first, as the servo motors will block the screwdriver.
For the pincer, check the txt file as I explain what the abbreviations mean.
Controlling the arm:
Because my robotic arm is connected to the rover chassis and controlled through Bluetooth, the code will be inherently different. However, I will provide it for you to modify, connect a cable from the arm's microcontroller to the computer and send character serial commands to operate the arm(this is how the Bluetooth app operates).
If enough people ask for the app, ill add it later. I made it long ago with MIT App Inventor, and from what I last remember, it doesn't work with iPhones, sadly and also release the f3d file after I clean it up.
