Skynet (SCARA Robot)

Goals:

• CAD and Program a robotic arm to print 3D objects

• Design to be mostly 3D printed with limited support

• Budget at less than $1,000

• Make it reasonably precise (±0.1mm)

Timeline:

• February 2021 - Present

Features:

• Mostly 3D printed construction

• Total reach of 468mm

• Magnetic endstops on proximal and distal joints

• 32 bit controller with trinamic stepper drivers

• Carbon fiber arms for reduced weight

• High precision (21.875:1 and 14:1 reductions)

• E3D V6/Volcano compatible hot end

How it Went Down:

My goals were to enhance my CAD and programming skills. I started by researching and developing a fun, utilitarian, and challenging idea, building a robotic arm to print 3D objects.  After many hours of designing and iterating in CAD, the printing phase began. More revisions were made during this time, ensuring components' fit and function. Version A of the frame has been completed. The programming phase begins.
