Hello everyone again! Doodl3r is my version of Breberky‘s EV3 Doodler. Doodl3r can draw using a marker by use of a scissor linkage. Two large motors drive the ends of the linkage’s arms at different speeds (depending on what type of picture you want). The basic core of Doodl3r is basically from Breberky’s LDD with a few structural tweaks, but the rest of the design is mine. Special thanks to Breberky who allowed his EV3 Doodler to be worked on by others like me. I recommend checking out his robots.
