I am imagining a very limited work space due to cable interference. Am I missing something?

[@cuhkc3roboticslaboratory443]

Yes, this type of robot (in this cable arrangement) would have significant cable interference.

[@cuhkc3roboticslaboratory443]

Yes! This type of robot is common within the cable robotics community, and for sure there has been many impressive examples before and after!

[@navid9852]

Great work. I assume the most challenging part of the design is cable management. I mean ideally you need some sort of ball joints at every connection point between cables and main body which should be difficult in real world

[@cuhkc3roboticslaboratory443]

Hi, thanks for the comment! Yes, it is important that the cables can freely move at both ends. One the base end, we use a 2 DoF rotating pulley, and on the end-effector we use a ring where the cables have some freedom to move on it.

Can you provide the published research paper of your work.

[@cuhkc3roboticslaboratory443]

Hi! We don't have a specific paper for this work in the video. But if you are looking for the research work of the lab on cable-driven robots you can find me on research gate or google scholar under "Darwin Lau" or you can contact me!

Damn that's a lot of extrusion for a simple frame.

[@cuhkc3roboticslaboratory443]

Yes, that's due to the maximum cable forces that the system can produce, and it's important to design future cable robots with more lightweight frames that can support the higher cable forces

3d printer for space?

[@cuhkc3roboticslaboratory443]

It could potentially be!

it can works as a big 3d printer?

[@cuhkc3roboticslaboratory443]

Yes it can!

[@dixeyfuly]

WELL done..

[@cuhkc3roboticslaboratory443]

Thanks!

[@dim3pap]

Great ; but what do you do with all those cables flying around, other then build a spider web.??.

[@noobdernoobder6707]

Motion simulation for an airplane simulator for example.

[@amos614]

Well done, C3. Looks simple but very challenging. The tension of the cable and the movement of the carrier will make the cable elongate and mis-align from time to time.

[@cuhkc3roboticslaboratory443]

Thanks! And yes, cable elongation is something that needs to be considered, whether it is calibration or adaptive control methods

[@zzzog2163]

Would be neat to see this applied to 3d printing

[@wei1224hf]

this is for VR game? Cool

[@FlashDrive356]

I don't think it is for VR specifically, but it could be used for it!

[@cuhkc3roboticslaboratory443]

@@FlashDrive356 Yes exactly!

Now put a chair and harness on the platform. The ultimate gamer ride. It would beat any roller coaster.
