Robots are available all styles and sizes, however some of the fashionable kinds for industrial purposes is the SCARA (Selective Compliance Meeting Robotic Arm). These have a number of levels of freedom, every of which rotates across the vertical Z axis. However they’re in any other case constrained, which might have benefits for sure purposes. For instance, they have an inclination to have comparatively excessive payload capacities. When you’re on a price range however need to dip your toes in, tuenhidiy’s SCARA plotter is an effective way to begin.

This can be a follow-up to tuenhidiy’s earlier SCARA design from a few years in the past. The brand new model is extra sturdy and features a homing characteristic, which is vital for repeatability. That is arrange as a plotter and the firmware displays that, however it will be potential to adapt the mechanical design for different functions. 

To maintain prices down, many of the construction is PVC pipe. Stepper motors present actuation through GT2 timing belts and pulleys. An Arduino Mega 2560 board controls these steppers via a RAMPS 1.4 board with A4988 stepper drivers. An interface module with a 2004 LCD, rotary encoder, buzzer, and button lets the consumer begin jobs.

On this case, these jobs are G-code recordsdata containing the motion instructions to breed the drawings. That works as a result of the Arduino runs Marlin firmware (fashionable within the 3D printing neighborhood). Using Marlin made homing simple and it accepts g-code that customers can create with many of the normal software program instruments.
