NASA Lunabotics 2026 - UNH LunaCats presents ATLAS 2.0, a regolith mining construction prototype.

I worked on the 3D printed wheels and chain guard. The tire is 85a TPU, and the hub is ABS. The tire membrane gets pulled over the inner diameter of the hub, creating a hard on soft seal, keeping iron dense regolith simulator out of the limit switches.

We use a drum to mine and deposit remote piles (berms). Here you can see the robot mining and traveling to another location via teleoperation for deposition.

We drove to Florida (UCF) from New Hampshire to compete. Unfortunately, during our second run, the robot did not move. In the first run it did, however the linear actuation for the drum to move close to the regolith didn’t work and we couldn’t mine. A poor performance for this year, which was quickly corrected after competing, as seen here.

Instead of having brim material generate outside the printers limits why not use that material to add ears along the edge of the buildplate with the center of the boundary the radius for the extra material

I had a print fail because it had a ~15mm brim on an object (not this one) that was generated over the edge of the buildplate on my Mk3s+as the model was large and complex. All that extra material was deposited in the same spot and caused downstream failure with repeated failed extrusion due to the lack of space for each failed extrusion attempt.

It would make sense to add a feature that used this extra material to add 'ears' (a circle of what is effectively a brim around the ends of long parts) to the edge of the prints, such that it increases build plate adhesion, reduces wasted material and time, and dynamically restructures brims to have the frankly necessary bugfix feature for preventing prints failing, like mine did last time.

I theorize that this would promote functionality as often when i try to fit big objects they have long edges that like to curl due thermal shrinkage, which is why people add ears at the ends because they resist this. The ears would be cut off such that they are more like semi-circles or splines perhaps.

I took some of my gfs vaginal/gut probiotics, and my skin cleared up the next day. I didn’t take it that day, and the skin got worse overnight. I took it again, and skin cleared up the next morning.

Here’s the active ingredients.

FYI, I’m a dude, I just tried them because they were making her crazy bloated and I wondered if it was just her (it mostly was).

Did I just cure my eczema? I joked with her, “what if this is the cure” but then it actually worked and I don’t know why!
