In-situ testing for space equipment is complex when it has to be developed on Earth, which is the case for literally all of it, at least for now. Typically, engineers and scientists developing the next Lunar or Martian robotic explorer would seek out exotic destinations that, while they look like they fit on another planet, were just more exotic parts of ours. The robotics team at DLR, Germany’s space agency, decided they could do better. So they built a 1500 sq meter test bed for their upcoming Martian and Lunar exploration bots.

Maglevs are one of those technologies that still look like magic, even years after they were initially rolled out. While they have long been a workhorse of the transportation systems of some major cities, they don’t often impact the day-to-day lives of people who don’t use them to commute. But, they might be invaluable in another setting – lunar exploration. There’s an ongoing debate about the best way to shuttle stuff around on the Moon’s surface, and a team from JPL and a company called SRI International think they have a solution – deploy a maglev track on the Moon.

Robots will be one of the keys to the expanding in-space economy. As launch costs decrease, hopefully significantly when Starship and other massive lift systems come online, the most significant barrier to entry for the space economy will finally come down. So what happens then? Two acronyms have been popping up in the literature with increasing frequency – in-space servicing, assembly, and manufacturing (ISAM) and On-orbit servicing (OOS). Over a series of articles, we’ll look at some papers detailing what those acronyms mean and where they might be going shortly. First, we’ll examine how robots fit into the equation.

Germany’s DLR has been hosting a series of robotic teleoperation experiments where an astronaut abroad the ISS controls a robot back on the ground. We’ve previously reported on some of their successes. Now it’s time for the next round of experiments, with one individual astronaut on the ISS controlling four separate robots to perform a task back on Earth.

Building with Legos is a favored pastime for many small children and adults. We’ve even covered some more space-oriented Lego sets here at UT. But, as the Lego movie points out, they constitute “a highly sophisticated interlocking brick system.” So why not take the idea underpinning Legos – that you can make anything you want out of a set of generic pieces and apply it to a much more serious scientific topic…like robots.
