How Accurate is the Dobot Magician?

Question:

Just how accurate is the Dobot Magician?

Answer:

Short answer: very accurate. To 0.007″ to be exact. Verified by an independent study student of mine using statistical analysis.
3bots In May of 2017  I purchased a Dobot Magician from an Etsy shop, as that was the only way to get them at the time. It is now available at In-Position Technologies here for $1499.00.  Use the code “chrisandjimcim”  or mention us on your PO and you will get free shipping as well as US based help and warranty service!
First thing I did, and when I say I, I mean an Independent Study student (props to Vincent Paglia , who will be going to RPI in August, see his info below!) was do an Accuracy test. They claim it is accurate to 0.2 mm, and our test on our robot proved that it was actually more accurate than that.  Try that with the robot you use for CIM class now! The only one more accurate in my classroom is my Fanuc, and it cost almost 15 times what the Dobot cost!

  For those of you into POE and “data” you can you download the spreadsheet with data points, graphs, ect here: 2017 Dobot Repeatability Data.  But this histogram says it all:
Dobot Accuracy Graph When all was said and done, our robot was accurate to about 0.18mm overall. That is 0.007″ for those of you in England… I must say, very impressed with the accuracy.
