智能机械臂-个性设计3D打印:

Hardware

The design goal for me was to build a Robot, which is stiff and strong, but still small and easy to handle. I used the common NEMA17 Step Motors, which provide enough power for fast movements and high precision.
Almost every moveable joint has at least one ball bearing to reduce friction, overall stability and accuracy. The robot is designed to have a low center of mass.
The robot is powered over a Computer Power Supply (12V).

The gripper is easy to replace and is held horizontally in every position, which simplifies programming and also reduces the cost and complexity of additional axies.
Most parts have a industrial look like cast Iron parts.

Software

The control system uses an Arduino Mega with a RAMPS 1.4 Board and A4988 Drivers. I provide a solid and working programming base for the Arduino, which handles the Interpolation of the stepper motors, makes all geometric calculations and smooth accelerations. It can handle some sort of GCODE communication over Serial.

The software can be directly used without modifying or additional hardware like sensors can be added.
To get you started, I have a simple Interface for your Windows Computer, which has a sequencer and manual control options built in.

You should already have some decent programming skills to modify and use the Software

Assembly

There are multiple versions of the big Gears. You may want to print them multiple times, if needed to reduce the gear slack of the rotational axis to a minimum. Depending on how high your Stepper Motor is, choose an appropriate leg height. Use Superglue to fix the bearings, if necessary. I have not cut any threads in the plastic. With PLA (maybe also others) you can 'melt' your thread through friction in, but you might want to drill the holes out a bit.

The Wiring of the Robot is not different from a 3D Printer that uses a RAMPS board. Use the official documentation: http://www.reprap.org/wiki/RAMPS_1.4

You can find details about the dimensions in 'doc2.pdf'
