Source – Another Marlins player tests positive for coronavirus – ESPN

Another Miami Marlins player has tested positive for the coronavirus, bringing the number of cases in their traveling party to 18, sources confirmed to ESPN.

Major League Baseball had already postponed all of the Marlins’ games through Sunday after the team’s recent outbreak.

“It is most prudent to allow the Marlins time to focus on providing care for their players and planning their Baseball Operations for a resumption early next week,” the league said in a statement.

The Marlins have remained in Philadelphia, where they played last weekend and have been undergoing daily testing. Sixteen players and two staffers have now tested positive.

No Phillies players or coaches have tested positive for the past two days, a source told ESPN, but an attendant for the visiting clubhouse did.

Postponements announced Tuesday were among a series of scheduling changes involving four other teams as a result of the fallout from the Marlins’ positive tests. The Athletic was first to report this latest positive test.

Dr. Anthony Fauci, the director of the National Institute of Allergy and Infectious Diseases, told the ESPN Daily podcast that he thinks MLB has “handled it well, to be honest with you, in that they’ve done virtually everything that you could do to try to get the main goal … to protect the health and the welfare of the players and of the personnel associated with the team.”

He added: “When I had discussion with some of the officials of different teams, as well as of MLB in general, we went over the different kinds of protocols that they would need … the testing and the things. One of the things that came up as a big concern is what happens if a cluster of players get infected, and how are you going to handle that? Would that wind up not only shutting down the team? Would it then impact on other teams that would be playing? So it was a consideration.

“I think we’re going to have to take it on a day-by-day, week-by-week basis.”

The Open Source Mars Rover, One Year Later – Hackaday

As the name implies, here at Hackaday we strive to bring you interesting projects every single day. But that doesn’t necessarily mean a project only gets one day to grace these storied pages. Quite the opposite, in fact. We’re always happy to revisit a project and find out how far it’s evolved since we last crossed paths with it, especially when the creators themselves reach out to give us an update.

Which is exactly what happened when [Jakob Krantz] recently wrote in to get us up to speed on this incredible open source rover project. We first saw this 3D printed Curiosity inspired robot a little less than a year ago, and at that point it was essentially just a big box with the distinctive NASA rocker-bogie suspension bolted on. Now it not only looks a lot closer to the Martian rovers that inspired it, but it’s also learned a number of new tricks that really take this project to the next level.

The articulated head and grabber arm don’t just help sell the Curiosity look, they’re actually functional. [Jakob] notes that he doesn’t have kinematics integrated yet, so moving the arm around is more for show than practical application, but in the future it should be able to reach out and grab objects. With the new cameras in the head, he’ll even be able to get a first person view of what he’s picking up.

Last year [Jakob] was using a standard RC transmitter to drive the rover around, but he’s since put together a custom controller that’s truly a thing of beauty. It uses an ESP32 and LoRa module to communicate with matching hardware inside the rover, as well as a smartphone clipped onto the top that’s displaying telemetry and video over WiFi. The controller is actually its own separate project, so even if you aren’t in the market for a scaled down Mars rover, its controller could come in handy for your next robotics project.

Presumably the multi-mission radioisotope thermoelectric generator (MMRTG) on the back of the rover is just pretend….but with this guy, we’re not so sure. Give him another year, and who knows.
