Makeblock sells a “Robotic Arm Add-on Pack for mBot and mBot Ranger”, but a couple of posts here say that it won’t work with an mBot because either the mBot isn’t heavy enough or because four motor connections are needed and the mBot has only two. In the description on the Makeblock site for this product, they say it’s for use with the Makeblock Starter Robot Kit, even though the name of the arm clearly says mBot.
Does anyone know whether it works with an mBot? And, assuming it does, is there any chance that there is interface code for it in the MakeBlockDrive library?
