The MeArm project aims to bring a simple Robot Arm well within the reach and budget of the average educator, student, parent or child. The design brief we set out with was to build a full robot arm kit with standard low-cost screws, low-cost servo motors and using less than 300 x 200mm (~A4) of acrylic. Where the MeArm project is different is that the problem it’s trying to solve isn’t about robotics but about getting people into science, technology, engineering, arts, and mathematics or STEAM. The more people who are involved with these STEAM activities the more chance we have of solving all of life’s problems, from cancer to getting humanity to Mars. There are well over 10,000 MeArms in the wild at the time of writing, we've just fulfilled a Kickstarter for the controller, which marks the start of a new chapter, taking the MeArm to anyone who wants to learn to code!


The MeArm is an Open Sourced Robot Arm. It's small like pocket-sized and that's for a reason. It can be cut entirely from an A4 (or more accurately 300x200mm) sheet of acrylic and built with 4 cheap hobby servos. It's live on our site for about $35 or £25 for those in the UK. All the files are linked on this project page and hosted on Thingiverse. It supposed to be an educational aid, or more accurately a toy. It still needs some tinkering but is at a good first draft state. There will be more instructions coming and no doubt more tweaks too.

Please get involved, build your own, break it, improve it and break it again.


  1. 4×9g Hobby Servo
  2. Cheapest servos you can buy. Want this to be affordable and hackable
  3. 1×A4 Acrylic Sheet 3mm
  4. The aim is to cut the whole arm from an A4 sheet, with a laser cutter
  5. 1×Arduino Uno or Leonardo
  6. 1×Various M3 Fixings
