From her message to us:
After getting a meArm, I went to work making a bigger stronger longer version. I doubled the size, added bearings to the joints and removed wobble from the base. This version uses an electromagnet instead of a gripper and can lift over 5lbs. The creation and success of this project has motivated me into making other styles of robotic arms. I hope this will be an inspiration for other to do the same. My design can be found on Instructables and Thingiverse.
And from her tutorial guide at Instructables:
Robot arms are fun to watch and more fun to play with. This design gives you the added bonus of building your own robot arm. Using a 3d printer and parts from the hardware store I was able to increase the lifting ability and strength of the original “meArm” kit. I added a few new features to correct issues I had with the original kit.
To view the original “meArm” check out his project at Pocket-Sized-Robot-Arm-meArm-V04. I purchased his kit from Adafruit and had fun putting it together and trying it out. I love the design, it looks like a robot arm in a factory. The original “meArm” is a good kit but a little weak for any real use. So I fired up SketchUp and warmed up the 3d printer. Time to make it bigger, stronger and longer! I doubled the scale, added bearings to the joints for smother movement, and bigger servos to help move heavier objects. I had some issues to overcome and have more improvements I would like to make but I am well on the way to a successful project.
…Special thanks to: phenoptix for releasing this project as open source. I have learned so much!
