TEST

Before we start to do tests, we need to do next actions:

On your Raspberry Pi type node assistant.js

On your computer's terminal type sam status and sam watch

Congrats! now you can test your robotic arm

CONCLUSION

The prototype worked very well, and is very useful to develop more complex actions with the robotic arm. however, I also had some difficulties such as:

• The board worked very well with 5 servos and when I used 6 servos the system was collapsed and the robotic arm made strange movements. Also in the servomotor configuration I changed to the value of: min_pulse_ms: 0.2 and the robotic arm worked much better.
• As I explained at the beginning of this tutorial, I had problems configuring the audio board, but this was successfully solved and now the MATRIX Creator board is very efficient even when it receives keywords at half a meter.

It's easy to say that in the future this prototype can serve as a model in every home, and may be, we will have a robotic arm at our tables to help us in multiple tasks.
