In the video below I show you the tests with a water bottle.
Now in the video below, the robot arm helps me unsolder a breadboard´s wire.
Finally, and as in the first version, I order the robot arm to move a box containing a lamp.
This was a good experience as I used a free tool to control my robot arm with the Alexa Echo Dot device. Also increase the functions without problems. The results were satisfactory and you can see them in the videos above.
