A Drawing Robot Kit That Can Be Assembled Into 4 Different Robots

Posted April 16, 2015

The mDrawBot is a drawing robot kit which includes four different drawing robots in the form of the mScara, mCar, mSpider and mEggBot. The Kickstarter project has already blasted past its $50,000 pledge goal. Designed to be customizable, the kits allow to build robots that will draw on walls and floors, and draw little faces on eggs.

mScara is a SCARA (Selective Compliance Articulated Robot Arm) driven by stepper motors. If you install a pen on mScara, it can draw pictures on a flat surface.


Replacing the pen with a laser diode, it can turn into a desktop laser engraver.

mSpider is a drawing robot which can draw pictures on a wall or a white board. Two stepper motors control the movement of mSpider though strings.


Theoretically mSpider can draw in a huge range by increasing the length of strings.

mEggBot is designed to draw on things that are improbable to print on, such as eggs or ping-pong balls. It can be used to write letters or to draw expressions on eggs, or to draw Easter eggs.


mEggBot is suitable to draw Easter eggs.

mCar is a three-wheel robot car. It contains two stepper motor drive wheels and a ball caster wheel. It can draw its own movement tracks on the surface. If you install a chalk instead of a pen, it can draw on the floor.

The kit includes a small programmable Arduino-like module, but you can supply your own and even add a Bluetooth system for uploading images wirelessly.

This kit consists of Makeblock parts and a powerful software named mDraw to control these robots.

mDrawBot contains over 60 components (and countless screws and nuts)

mDraw is a powerful software designed for mDrawBot, which is an open source project hosted on Github. After installing the mDraw software, you can import images and make the robot draw them. Here are some features:

  • SVG import
  • BMP to SVG conversion
  • Support Gray-scale laser engraving
  • Several customizable parameters including limit switch location, stepper motor direction, drawing range
  • Zooming the drawing with the mouse wheel

mDrawBot kit cost $168 and include all the parts necessary to create multiple robots. For $299 you can get a laser engraver pack that allows you to shoot high-powered lasers at your surface. The team hopes to ship in May.
