Hi Chris,
I just started building my AR3 recently, and saw that the AR4 was just released. I noted in the manual that the primary update is the use of the teensy 4.1, which I accidentally ordered for my AR3 build. Since I ordered most of the electronics for the AR3, would it be better to order a teensy 3.5, or do you think it wouldn't be too much extra work or cost to outfit the robot with the electronics necessary for the 4.1?
Thank you!
Al
Update 3 :)
Using AR4 software for calibration and movement right now, will be using Python ROS (https://github.com/ongdexter/ar3_core) and klampt (http://motion.cs.illinois.edu/software/klampt/latest/pyklampt_docs/) for control in the next month. Hope to show you some ex vivo surgical studies in the next couple months!
