I am no longer surprised to find things that use Hardware Libre since it is becoming one of the best options, something that until recently did not happen. But there are projects that surprise like the prototype of water robot what has appeared and what does it use Arduino to run. The prototype has been created by the Institute of Technological Education of Greece and its operation is the same as the operation of Arduino in 3D Printers: control the movement of motors.
In this case, the aquatic robot comes equipped with Arduino Mega and a Special firmware that controls the use of the membranes and the movement that they have to make. It also collects the ripples of the water so that the robot is able to modulate the movement of the membranes that it has based on the ripples of the water.
The tests of this aquatic robot are being positive and interesting but the best of all is that an institution has considered using the Hardware Libre and not create your device or opt for a more exclusive option. The robot, in addition to having Arduino Mega, has a 7,4 V Li-Po battery that will power the board, the video camera that it has built-in to make recordings and the bluetooth module that it uses to send and receive external communication.
According to the creators of the project, the battery is more than enough to power and give autonomy to the robotHowever, I really doubt that the battery does that, since there are more than four servo motors plus Arduino Mega, the bluetooth and the video camera that it has to support. In spite of everything, it must be remembered that it is a prototype, it is not a final robot or even a stable version of the robot. What's more, I personally believe that this project will be incorporated into another project before the final version is released since I don't see much use for this robot What do you think? What do you think of this robot?
