MIRoC 2014. Rope Climbing: Old Design & Main Concerns

[shahmi sulaiman]

Salam & Hi guys,

Here are designs of previous rope climbing robot. 

and this is how the robot supposed to move:

http://www.youtube.com/watch?v=qSjn8b8uwU8

Basically the robot operates using 5 servos motor as shown in the video. I've been thinking about this and in my opinion, for this year we should adapt the same concept as previous year with additional improvements/updates such as improving the gripper or using powerful motor as prime mover. Just to make sure the robot run smoothly, faster and perfect! My concern is the time limitation we have. Last year we spent a lot of time on research on mechanism. So we are not going to start from zero, just continue to improve whatever things we already researched.  Besides, we will hv more time for Joe to program and testing the robot. So what do u guys think?

kot?? nice.

For me, I dont have any problem with this concept since it still can perform the task, but one thing that I really concern about this concept is it requires a lot of energy just to complete one cycle to move it a step forward and i think the effort for it 's one cycle with the time it consume just not worth it. remember the actual rope during gamefield is not just the horizontal rope. It is better if you guys can come out with a simpler and reliable mechanism and concept. I'm thinking about how the leech(pacat) movement and try to copy it's concept for this rope climbing robot.

Ajieb & Joee: I think a shorter robot body would required less energy consumption to rotates its body together with the load. Replacing a powerful motor to rotates the body also should improve the time taken per rotation. Its just my concern..if u think other concept works better, then lets go ahead and find it out . Imitating leech movement is a good idea though. 

KH: As i remembered, contestant from UiTM who won the game was using this concept. Correct me if i'm wrong :D

Shorter body surely will reduce the energy consumption but it also reduce the distance covered per cycle thus increase the time taken to cover the whole distance.we can increase the speed per rotation/cycle but it will give another bad effect when the rope bounce vigorously during climbing. Right now we have alot of time to brainstorm the idea compared to last year so keep the ideas coming guys. :) I'm in the phase to explore more about the leech method and i'll try to make the simulation so that you can get a better view about this concept.

The winner for last year is the one that climb like ghost.even i cannot brain how their mechanism works.hahaa..the runner up using the same concept but they should be disqualified since they exceed the extension limit during climbing but the organiser didnt take any action.

Dear MIROC and ROBOCON Technical Members,

Greetings. As mentioned before by Dr Haris, the engineers from Iratech (the new electronic board) will be coming over to UTP and stay from 21st January 2014 until 28th January 2014. Therefore please discuss with your team leaders and directors to join the workshop. The detail of the schedule will be notified later. 

Thank you.

Best Regards

Hoong Wei.

Yup. Joe masuk.

Assalamualaikum. Sorry for the late participation. Just got back frm dengue. Im saiful btw. Just a thought, how if the clamping mechanism stays, but the swing swing motion is replaced with a simple slider crank mechanism. To pass the pulley, just let go the front clamp, and the robot's weight should make it drop, then the robot extend, grip back the rope, the back let go, the robot retract, the rear grip back the rope. Am i making any sense?

Saiful, do u have any 3D modelling softwares like Autodesk Inventors or something? could u design it and bring it to our next meeting? we'll see if your idea can work or not.
