31/03 : Research (Programmation)

A project log for Sonar Blind Project

The Sonar Blind Project tends to replace the blind mans canes with a wristband that works with sonar concept.

Almost every components are missing, so we can't do that much. We chose to make more research, about programming now.
We also have decided that, indeed, we should use a time of flight sensor and an ultrason sensor. We are going to set 2 modes on our device : an interior mode, that is going to use the time of flight sensor (2 meter range for a better accuracy), and an exterior mode, that is going to use the ultrason sensor. We will need a program that reduces the cone of the ultrason sensor from an angle of 15° to an angle of almost 0° in order to use it properly.

One member of the group has to focus on the time of flight sensor part, another one has to focus on the ultrason sensor : that means receiving the information and process the data.

The last member has to focus on the vibration part, that means using the data from the sensors to activate the vibration motors, depending to the received signal.

We are struggling to decide if we are going to use the ultrason sensor. We will find out after a few tests.

So now we will just need to wait for the components in order to test them.
