Man what a day. Sorry I’m just not able to make a decent video of the #cable-cat.
First it’s raining all the time so the cable was full of water and doesn’t allow me to move fast due to risking water spalshing and shorting the electronics.
Then it just stops raining to start again really makes it quite impossible to do it these days. But when you actually got properly one good take the camera failed saving the file.
So just this very short video that no one could say I’m too lazy or not willing to share And nope I’m not giving up on this. A better video will follow as soon as possible. prmised.
Thats an interesting idea! Hmmm
We thought about adding an gyro and make it work like a gimbal.
But maybe some balancing would be great for the bigger version as we thought about DSLR cams which are quite unbalanced depending on the Objective. So we definitly need something to keep banlance.
Thanks for your input!
Awesome input @Lukas_Merz and @Sebastian_Schmidt
Maybe a combination of counterweights to stabelize and counter moves sensed by a gyro would be a good way to go.
But also to mention is that the cable was very flexy which also causes in that low hanging. It comes loose at least two times and it slightly kisses the ground while moving forward.
While the moving mechanism seems to like the cable tautly to get a good contact and grip.
Another cable may works better in general
With all those rain inbetween we really haven’t that much fun at all and the cable was really wet even as we shaked it arround several times, just glitchy.
Next time we use an old phone i found matching the cam cage which was design for a #GoPro which is on a field Trip with @Michael_Schwerin the designer of this thing.
This would allready make it better, while also I just packed the LiFePO cells and the electronics on the back to the DC Motor. I will bring it to the front and may add some counterweights if nessesary.
Keep on with your input as it really helps the way it goes.
Thanks
Maybe a design in which all wheels are driven are better.
Design changes are minimal
One easy way would only add a few gears, the other way would be build like work like modern printers (I dont know how ti name it in English, I mean the “rubber cord” with its tooths on the inner side.
Or you can try to let your cable not only to go through the three wheels, but sling it one round on the middle driven wheel. It gives you more grip.
Also you can try add a layer of silicon to your wheels.
well @Markus_Osmers_mo22 the counterwights will increase overall wight. Bad idea. Put the Battery in top of the whole thing for example.
The grip is not a big problem since the motor has to mough torque anyway and your acceleration will be smooth based on the slick on the wire…
@Sebastian: they call it just drive-belt or tooth-belt. Actually we have some hot-glue in the driving wheel, which has a tooth profile. So with a dry cable it work almost OK, but still I’m sure a bigger diameter and less flex would make things better allready.
@Lukas of course the thing is very heavy at it is. I will definitly try to get the stuff mounted as balanced as possible for the next run.
May it comes out pretty good. well I hope so.
As we allredy decided to make a smaller version of it, We also will see to make it as light as possible in the first place.
And nope I’m not giving up on this. A better video will follow as soon as possible. prmised.
