In the summer of 2019 I found myself with a bit of time on my hands. So a great opportunity to do some experiments with soft robotics. The first step was ordering a lot of silicone. This isn't cheap, however 1kg of type shore 8A (very flexible) will go a long way and it is super multi purpose. luckily [[https:// | In the summer of 2019 I found myself with a bit of time on my hands.

It lets you get the hang of both motor control and pouring silicone. |

The winter festival is a weekend long event with, by and for our neighborhood. It's free and anyone is welcome to visit. The soft robotic bubbles garnered a lot of attention especially with the many kids at the festival. The bubbles themselves proved to be very robust which made the installation weirdly interactive. It is nice to have something to show for your work and I really enjoyed my time at the festival. | The winter festival is a weekend long event with, by and for our neighborhood.

- | The festival bubbles have some unresolved challenges. Time constraints made the neopixels run a selection of the code used to test LED-strips.Thankfully the Adafruit strandtest.ino code has some beautiful parts, especially the rainbow chase can be quite nice. Another weak point was that it wasn't possible to control the airpumps and the neopixel animation at the same time. This made the whole thing look very rigid. | + | The festival bubbles have some unresolved challenges.

When I heard the announcement of the raspberry pi Pico, I got pretty excited about the PIO functionality. PIO seems to be perfect to control both neopixels and airflow, while still being able make decisions with the main loop. So a great prospect for soft robotics control. Thus I decided to reincarnate the festival bubbles into a desktop bubble, a portable soft bubble for code testing, prototyping and showing of soft robotics. | When I heard the announcement of the raspberry pi Pico, I got pretty excited about the PIO functionality.

The next milestone will be adding the pressure sensor and making it battery powered. My main goal is to turn the Desktop Bubble into a learn guide and the electronics into a feather wing. Hopefully this will make starting out easier and also encourage more people to give soft robotics a try. It would be nice to see more hobby level projects using these techniques.So if you see something cool let me know! | The next milestone will be adding the pressure sensor and making it battery powered.
