it's about robots that are untethered that can jet up from water and glide in the air for 26 meters.

Manta rays and flying fish transition from the sea into the air in breathtaking fashion. Now, a team of scientists has developed aerial-aquatic robots that can glide and have a similar ability to transition seamlessly between the air and sea.

The new type of robot could be used in areas where quick movement is needed, such as disaster relief zones, reservoir management, and agriculture.

A new propulsion approach

Researchers have created untethered robots that react with water to generate combustible gas in order to blast from pools of water into the air. Once in the air, the robots were able to glide for a short time before reaching the ground.

This new approach could be used as a critical design feature for aerial-aquatic robotics. These could be used in disaster response for floods, agriculture, reservoir management, and oceanography.

The robots could also be used in situations where time and resources are of the essence. We can imagine them being used in remote watery terrains such as caves to find people who have been trapped in dangerous conditions.

Transitioning from water to flight

Designing a robot to move seamlessly from water to flight requires a power-intensive unit that is especially challenging to make in a small size.

The more traditional method of combustion usually requires a tethered robot connected to supplies. This would make it difficult for the robot to glide.

Raphael Zufferey and his colleagues have designed untethered robots that they were able to launch multiple times from the water using an impulsive actuation force that was over 25 times the robot's weight. After the launch, the robot was able to immediately start gliding.

They managed this by adding a small reserve ( 0.2 grams) of calcium carbide powder to the robot, which reacts with the water when exposed. When reacting, combustible acetylene gas is formed, which is ignited in a small combustion chamber, allowing the thrust that launched the robot out of the water like a manta ray.

The prototype could achieve a flight distance of 26 meters and was able to run a total of 22 flight on 160 grams of calcium carbide powder, in an indoor tank and an outdoor pond.

The robot can operate over small waves, though big ones are still a stumbling block. The researchers will look to make future models more robust.

This article talks about robots being able to shape-shift by dissembling and reassembling. These are robots that will drive passengers across a canal.  These robots a  being developed as part of the ongoing "Roboat" project between MIT and the Amsterdam Institute . The robots are good for moving both people and good across a body of water and collecting trash. They are hoping to make the "Roboats" a new way of transportation so that the roads of Amsterdam are not as crowded. These robots can also  locate each other, agree on how to break apart and reform, and move around freely.

This robot, developed in the Dynamic Systems Lab at the Italian Institute of Technology, is able to pull a 3-ton passenger plane. Named, the HyQReal, it is powered by four hydraulics, one in each leg. The scientists behind this robot have been developing others like it for more than a decade to help humans in disaster situations, agriculture, and more.

Using data from electrocardiograms (a test used to measure the electrical activity of the heart), a robot can "scan" a patient and accurately guess their age and gender. While not extremely useful or world-changing now, if similar, more complex robots are created, Baymax might be a reality! (At least, that's my hope)

This article highlights the new robots that NASA is making specifically made to  climb cliffs on Mars. This robot has been in testing for years but was recently tested in Death Valley. It has hundreds of tiny fishhooks on each of its 16 fingers. This allows it to scale large rocks and uses a scanning system and artificial intelligence to get smarter as it climbs. It can also drill into rock without sharpening and extract samples.

MIT engineers have created a small robotic thread that can be directed by a magnet. They are planning on applying it to brain surgery and preventing permanent damage from strokes. The thread is small enough to navigate through brain vessels under the direction of the remotely controlled magnet, meaning doctors can be in a Ohio, performing an operation on somebody in New York. The remote abilities of the thread also keep the doctor away from potentially harmful radiation of fluoroscopy, which is used to show images of the surgery.

When searching for a project a found a project called the Roomba https://www.irobot.com/roomba
This robot is a self driven vacuum cleaner. This vacuum uses  Dirt Detect ™  technology  which will detect the more dirty parts of your house. To get there it has sensors all around it so it can get along walls, under beds, and right around furniture. once it gets to the dirt it uses 3-stage cleaning  to pick up all the dirt.  First it will loosen the dirt, then pull it into the container that is located inside the vacuum.

There are a lot a different interesting robotics projects. Including making a remote controlled robot. Most things in robotics have something to do with robots and tech. Another cool one is human detection robot. The human detection robot is radio frequency and RF technology. This robot is controlled by using received data. There is a human detector sensor in the robot also. Almost all 25 of these projects are of robots. A lot of these robot are to do stuff that human usually are supposed to do (fruit picking robot, window washing robot, Stair climbing robot, and more).
