3D-printed, driverless boats developed

The self-driving vessel has a high degree of operability and precise control.

They can be used low

Make batch manufacturing more feasible.

Scientists at the Massachusetts Institute of Technology have designed a 3D fleet.

Printed unmanned vessels that can transport goods and personnel, helping to ease road congestion in waterways

Wealthy cities such as Amsterdam, Bangkok and Venice-

The canal extends beside and below the bustling streets and bridges.

The self-driving vessel has a high degree of operability and precise control.

They can be used low

Make batch manufacturing more feasible.

In the future, the researchers also envision that driverless ships will adapt to night-time city services, rather than further reducing congestion on roads and canals during busy days.

'Imagine transferring some of the infrastructure services that are usually on the road during the day --

Waste management, waste management

'Until the middle of the night, on the water, use a team of autonomous ships,' said Daniela Ruth from the Massachusetts Institute of Technology (MIT. The boats -rectangular 4-by-2-

Rice hull equipped with sensors, micro-controllers, position trackers and other hardware-

Can be programmed as self

Assembled into a pontoon, concert stage, food market platform and other buildings in a few hours.

'Similarly, some activities that are usually carried out on land, and activities that cause interference with how cities move, can be carried out temporarily on the water,' Rus said . '.

These vessels can also be equipped with environmental sensors to monitor the waters of the city and gain insight into the city and human health.

In order to make a vessel, researchers 3-D-

rectangular case was printed with a commercial printer, producing 16 sep pieces of arate spliced together.

It took about 60 hours to print.

Then seal the finished hull by pasting several layers of fiberglass.

The power supply is integrated into the hull, Wi-

Antenna, GPS, small computer and micro controller.

For accurate positioning, the researchers put the indoor ultrasonic beacon system and the outdoor real-time

Time Dynamic GPS module, allowing centimeters-

In addition to other indicators, an inertial measurement unit (IMU) module is included to monitor the course and angular velocity of the vessel.

The boat is a rectangular shape, not the shape of a traditional kayak or catamaran, to allow the vessel to move sideways and connect to other vessels when assembling other structures.

The researchers used an efficient prediction.

The control platform runs their algorithm, which can quickly determine upcoming actions on similar systems and increase the speed of the algorithm by two orders of magnitude.

When other algorithms are executed in about 100 ms, the researcher's algorithm takes less than 1 ms.

Innovations in design and manufacturing, as well as faster and more precise control algorithms, point to viable driverless ships for transport, docking, and self-control

The researchers said it was assembled into a platform.
