Tried with both acetone and chloroform to degrease the surface / make it rougher but neither worked, the latex doesn't stick properly.
One problem could be that the diameter of the thread decreases when you stretch it. There is a lot of extra room for the thread when it is stretched out fully.
Tried to superglue the layers to the thread but I couldn't make it work properly unfortunately. The thread lost all elasticity and got stuck in a semi stretched state. I think i need to find another way to keep the layers straight.
If i use a tube i could glue them together, but then i can't stretch it anymore.
Tried making one arm with elastic thread, based on the model from yesteday. 2mm ish acrylic with spacers, 20 layers. The market was closed by the time i got there, so will try to go again today to see if they have any other material.
It is pretty flexible and there's not too much resistance, however i think maybe rubber bands of the same size could be better? Also I think it could be possible to limit it to three threads instead of four as well to reduce resistance even more.
Currently it just chooses a random servo and a random angle between 0 and 180. It goes back and forth like a a conversation, but I think it is not that clear.
I think I should make it so that it always chooses an angle that is far away from its current position (fixed this, just not shown in the video). Alternatively maybe do a "Simon says" version instead, where object B just copies A everytime? Or a version where they both copy each other but add on to the loop. E.g. first A sends [180], then B sends [180, 45], A sends [180, 45, 160] etc.
Or if it should just be an off - on situation?
Only did four servos this time, should do a version where i use more servos as well.
Testing the power source with eight servos running simultaneously.
Different alternatives for the spool. Tried to match the rest of the object a little more with these.
A few variations for the object. Still have to make a spiky one.
If i place the object in a 45 degree angle inside the tank i can control each end of the obcect as well as the middle part. The middle part can be pretty much fully controlled as it will have 4 motors pulling in different directions. But for the ends to work, the motors need to be paired, e.g. the combined value of the motors can't exceed 180 degrees -> if one motor is turned 120 degrees, the other needs to be turned 60 or less (for the object to be able to move up and down without the thread becoming loose enough to jump off the bearing. However, there may be a lot of water friction if I use complete discs?
Instead of pull each arm outwards. It will pull the arm in the opposite corner of the motor to turn / twist the arm. Similar to the kinetic snake arms. But i think this one may be impossible as the arm closest to the motor will collide with the thread.
Laser cut the base shape and connect it together with gussets. Then connect the "spikes" to the base shape with elastic band. The layers need to be pretty tightly knit together for the shape to bounce back to its original shape.
This one is a combination of an acrylic cage and silicon. With a cage like this the silicon can be attached on the inside. Would also only need a 2D form.
Another similar to the first one, just in a circle instead. I think this one has less options in terms of possible distortion. As its a circle the distortion will in way be mirrored. Also if i use rubber bands / flexible bands to keep it together, there is no way it will retain its shape. Will end up in a square.
The rubber bands used here are way too strong. It is very stretchy but requires too much strength for the servos to be able to pull it. The model itself is also way too big.
LED chip test. This is a single LED chip placed 9.5 ish cm away from the tank. This is more or less the same as the LED strips, just a different pattern / distance. Would of course use just the LED chip and not the case around it. Found this laying around in 504.
The light is much warmer than the LED strip. It also has a pretty distinct hotspot, but i think this may be becuase of the case and not the light itself. The box that keeps the tank up is also casting a shadow which obstructs the light.
