Great Hunt!
Wow this is great. A few weeks back their was a similar hunt I was completely fascinated with but this robot was only able to draw on a wall or whiteboard. But your hunt opens so much more possibilities to fiddle around with and express your creativity the way you want (looks like with the modular build you can do even more than those 4 things they indent). And toping all of this it is even way cheaper than the previously hunted model.
Keep on the good work!
You are absolutely right,one can easily perform 4 types of things with the help of mDrawBot in a very smart and simple way. Thank you so much for the appreciation for my work means lot :)
