Some of the robots on the International Space Station, some only one-way tickets

JAAA recently installed a robot on the International Space Station, whose main role is to save astronauts' time.

The name of the robot is Int-Ball, which is a spherical robot equipped with a camera. It can be controlled by a team on Earth, can fly in the space station (there should be no flight in the space station...), move with a series of thrusters, and then record what is happening in the space station.

Int-Ball is manufactured entirely in 3D printing using existing drone technology. It looks like a beautiful blue eye floating around. According to JAXA, robots can move through autonomous flight anytime and anywhere, and can record images from any angle. It weighs 1kg, has a diameter of 15cm and has 12 propellers.

Int-Ball was launched into space by SpaceX's Falcon 9 rocket on June 3 this year and is now in the Japanese experimental cabin of the space station.

JAXA estimates that astronauts spend about 10% of their time doing the work they do and send the images back to Earth for analysis. With Int-Ball, astronauts have more time to experiment and repair the space station.

Int-Ball is not the first robotic passenger on the station, but rather a paradise for robots.

Lei Feng.com reported that as early as 2006, NASA NASA sent three free-flying small robots to the International Space Station. These robots, called SPHERES, conducted experiments for up to 600 hours in space, carrying out rich experiments including autonomous flight, space station navigation and mapping, and even running a program written by middle school students in team competitions.

SPHERES needs to be under the supervision of astronauts (because they are more flammable, etc.) and rely on a disposable alkaline battery pack to power the CO2 propulsion tank.

SPHERES later had the successor Astrobee, a new platform that can operate completely autonomously and safely on the International Space Station, the biggest improvement being the propulsion system. And it uses the electric propulsion system completely, and it can charge itself through the docking station.

Astrobee is also much more free, and it can navigate autonomously in the US, EU and Japan cabins of the International Space Station.

Custom Slip Ring

What is a slip ring?

A slip ring is an electromechanical device that allows electrical current to flow through a rotating assembly. It is often used in conjunction with a commutator to create an electrical connection in a rotating system. The device consists of a number of contact rings mounted on the rotating assembly and two or more stationary contacts. When the rotating assembly is rotated, the contact rings pass by the stationary contacts, creating an electrical connection.


Types of slip rings

A slip ring is an electromechanical device that allows the transmission of power and electrical signals through a rotating assembly. Slip rings are commonly used in applications where it is not possible or practical to make a permanent electrical connection, such as on a rotating antenna, wind turbine, or radar dish. There are many different types of slip rings available, each with its own set of benefits and drawbacks. Some of the more common types of slip rings include fiber optic slip rings, rotary unions, and contactless slip rings.


Advantages of custom slip rings

When it comes to slip rings, custom-made ones have a lot of advantages over the standard, off-the-shelf variety. Custom slip rings are designed specifically for your application, so you can be sure they`ll meet all your needs. They`re also made to order, so you can get exactly the features you want. And because they`re made specifically for you, they`re often less expensive than generic slip rings.


Disadvantages of custom slip rings

In many industrial and commercial applications, a custom slip ring is the best way to transfer power and/or data between two systems. While custom slip rings offer many advantages, they also have some disadvantages. In this article, we will discuss the disadvantages of custom slip rings.


One disadvantage of custom slip rings is that they are often more expensive than other types of electrical connectors, such as wire harnesses or connectors. Additionally, custom slip rings can be difficult to install and may require specialized tools. Another disadvantage is that custom slip rings are not always as reliable as other types of electrical connectors. They can fail prematurely if not properly maintained or used in the correct application.


Conclusion: When to use a custom slip ring


A custom slip ring is an electromechanical device that allows for the transmission of electrical signals and power between rotating and stationary components. The use of a custom slip ring can be beneficial in a number of ways, including improved performance, increased efficiency, and longer life. In some cases, a custom slip ring may be the only option available for achieving the desired results. When considering a custom slip ring as an option for your application, it is important to understand the different factors that will impact its performance.
