Hello everyone!
Yes, I am new to the forum.
I came across a few parallel SCARA robots as I was looking for a new project to work on, as I just finished with my 3-D printed robotic arm.
My inspiration was drawn from this youtube video

From my understanding, 2 servos will be needed (which I have recently ordered, I went with teknic). I was planning on using an Arduino uno but realized that I could only control one servo at a time using an Arduino. I am leaning towards a raspberry pi now as I have read some people having success with this. If someone has had success with possibly a Arduino Mega, please let me know!
I have been teaching myself reverse kinematics since it seems to be necessary in order to move the two arms with an end effector to a specific point. Though, I am kind of thinking of using Solidworks and finding my angles from there. (Please let me know if there is a better way to go about it).
I noticed that one servo is lifted above another. I am assuming this is because it helps one of the arms clear the other in order to create a 360 work envelope? Is there a specific distance that the motors should be placed and lifted? I am having a difficult time finding any information about this. From my previous knowledge, I am assuming that the length of the arms would dictate how far the servos would need to be in order to create a 360 work envelope? I suppose what I am here for is to ask for advice in building one from scratch.
Thank you so much in advance! I appreciate any advice!
