LittleArm V3 Arduino Robot Arm

We want to build STEM kits that gets kids excited about technology. So far we have created and launched nearly 10 kits. And now we want to improve our original Arduino Robot Arm again.

In 2016, a guy in a garage built a small robot arm using an Arduino Uno and his 3D printer. After tons of people asked him to turn it into a kit, Slant Concepts put it on Kickstarter. It was funded in under a week and hit more than 260% of its goal by the end.

With the great response we took all of that feedback created a simplified and rugged version of the arm called the LittleArm 2C. It ended up raising 560% of its original goal.

Now, Nearly 3 years later, we are launching the third generation of Arduino Robot Arm. The LittleArm V3. We have again taken all of the feedback from hobbyists and classrooms all over the world to further simplify the kit.

The V3 is the third version of the LittleArm that we have made. It has fewer parts and relies more on 3D Printing than any of our previous kits have.

The LittleArm Original was the very first kit that we ever created in 2016. Then we followed that in 2017 with the LittleArm 2C. And it took quite a while to find a way to improve on that on. But we found it.

• Gripper - We have turned 8 pieces into 1. This gripper eliminates complexity that made it difficult for younger kids to work with the kits. It is also able to grab more stuff.
• Overall Design - Sleeker with even fewer screws and complications. Every piece has been optimized.
• Improved App and Demos - We have updated the software for the arm and will be releasing new demos.

Overall, we figured out how to further optimize all of the parts to make easier to put together. the gripper that was once 8 pieces is now just 1 piece. Only 2 of the 4 servos need a screw, so kids don't lose those tiny set screws in the rug. And we have made it even tougher so it can take the abuse of classrooms and groups better than ever.
