UPDATE: The Astrobee Challenge Series has ended. Huge congratulations to everyone who participated! Stay tuned for upcoming NASA Contests on Freelancer.


The NASA Tournament Lab and Freelancer have teamed up to help crowdsource solutions to the most complex problems being faced by astronauts on the cutting edge of space exploration. Starting in 2015, this partnership has already spanned solutions from 3D tools for robotic astronauts to smartwatch mobile applications used for time tracking and important station updates.

In the latest set of challenges, we will be designing a robotic arm for the Astrobee, the next generation of free flying robots on the International Space Station. Get involved today and help NASA push the boundaries of human imagination and innovation.

The Robotic Arm

Create the plans for how the robotic arm will be built. Participants will be pre-selected based on suitability to the task by filling out a survey then hired to create the plans for the arm.

Robotic Arm Building

Once the plans are complete, contest challenges will be posted. Freelancers will be able to compete to create the best designs for all the individual pieces necessary to build the arm.


Learn more about free flying robots such as the SPHERES, the Robonaut and their role in space exploration aboard and beyond the International Space Station. More media will be added as the challenges get completed so check back soon!

Astrobee Challenges Series

NASA is designing a next generation robotic assistant to support astronauts on the International Space Station (ISS). The assistant will fly around inside the ISS, perch on a wall-mounted handhold ("Handrail"), and orient a camera, as directed. NASA has already designed the free flyer part, called Astrobee, and had looked to the freelancer community for great solutions for an attachment and orientation arm.

Over the next several months, ~$25,000 will be awarded, spread over more than a dozen contests, with individual prizes ranging from $250 to $5000. Each will ask for solutions to a particular (sometimes overlapping) piece of the attachment arm. Each contest has been defined to be solvable on its own, but you may choose to compete in as many contests as you wish. Winning solutions may be incorporated into the robotic arm design and used with Astrobee for years to come.

Application Challenges

Getting live updates and tracking your time is mission critical aboard the International Space Station. Our freelancers developed smartwatch concepts and applications for Astronauts to keep the ISS operational at all times.

Robonaut Challenges

Meet Robonaut R2, the humanoid robot who takes on the most dangerous tasks in space. For these challenges freelancers created 3D models of tools R2 uses to keep the ISS astronauts safe.

Robotic Arm Architecture

In a pre-cursor challenge, NASA selected 30 freelancers to suggest plans for Astrobee's robotic arm. These submissions informed the design of the contests that are open now and over the summer.

Branding Challenges

Inside of NASA there are many initiatives and programs to improve space exploration and the lives of those involved. To help further this goal, our freelancers improved the branding on logos, trophies and banners used at NASA.
