If I am not mistaken that would be the tensioner plate, and if it is, you could also attach a sensor at the point, or you could place it inside the gearbox extension which might be safer

I would have to say this looks like a fun CAD project to work on, but very unpractical to combine those two systems in real life. By adding a telescoping section to a poof style 2-jointed arm you are basically adding a redundant system to achieve the same goal. The whole point of the lower joint on the 'poof' style arm is to extend the arm to reach farther, higher ect. which can also be achieved by a 'pink' style telescoping arm with a lower joint. So unless you really can't achieve your goal with a 'poof' or 'pink' style arm, I guess this system could work... but that's very unlikely and makes this kind of system unnecessary.

The one advantage I can think of is having to reach up, and far over a large object. However, can't remember too many times this would be beneficial.

congrats im very impressed with your cad work. do u have any other completed designs? and how long did this take to draw this up? im sure u included all the measurements and materials in your design or you wouldnt have been able to calculate the weight and also to do that i am sure u were able to calculate the load it can take in different directions. if so what type of aluminum do u intend to use? is this design just an after thought that u wanted to get opinions about or is this something u want to use? if you are planning to use it idk if u should show the needy eyes all us competitors ur plans like this. again i wanna stress that i am very impressed with ur cad.

He does. He's actually one of the three most shown Solidworks designers on these forums. One of your teammates and another Northern California member are the other two. Search CD-Media by the uploader using these three members' names and you'll find plenty.

[joshy1323]

thank u erich i am relatively new to CD and im very good friends with RC. i see his designs before this site does usually and he is training me on how to use solidworks right not but im already used to his work im more interested in what others have to show. i did not kno that he was so well known on here btw i guess it adds up though since im often making fun of him for always being on here. btw i see ur kind uf well known on CD and im curious as to how to make a name for myself. RC says just start posting but i feel like i have no voice as a new member. any advice?

Follow RC's advice. We all start from the same place. If you aren't comfortable, try the Chit-Chat forum until you get a feel for the site. Also, if there's a forum that interests you, that can also be a good place. (For me, it was Rules/Strategy.)

[joshy1323]

thanks erich u sound just like RC haha. im still getting used to using the site. i have not really explored far out of the list of recent activity and i didnt even know that there was a chit chat part on here. ill check that out though thanks.

As a good friend of RC's, welcome to CD
Post if you have a valid question that hasn't been found through the "search" feature up top. Seems like we share a common teacher.

I would start by reading every single stickied thread. They're usually up there for a reason. Next, clean spelling and grammar helps a lot. After that, don't be afraid to ask questions (assuming you already searched)!.

thanks for the advice. sorry if this is a stupid question but what is a stickied thread? is that what this is? and ya RC said that my texting talk has got to go when im on here or i would not be taken seriously. btw do u guys only know him as RC? i keep writing his real name and then i have to go back and write RC instead because i dont know if anyone will know who i am talking about or not. and i apologize for clogging up this topic room can someone tell me how to reply to someone without putting it up here for everyone to read? im not anything close to a computer wiz.

Here's some advice:
Stickied thread: If you go into a forum here, near the top there will be a thread or several that say "Sticky: [thread name here]". Those are the Sticky thread.
Real names: Look at someone's profile (what you see with their username when they post) to find out if they have/use nicknames or real names. I don't remember RC putting one, but I haven't looked recently.
Replying privately: click a person's username. A list will show up that says something to the effect of "View public profile" "Send Private Message" and some other things. Select the Private Message (PM) and type what you need to.
One other thing: Editing posts. There's an "Edit" button on each of your posts for a short time. Saves you the trouble of posting again to correct a post. Can also be used to delete a post.

wow believe it or not he is just a regular student at my highschool. i was not aware that he had such an influence. and thank you i appreciate it. i hope that i am not hurting his reputation with my presence on CD.

I DO THIS STUFF FOR FUN.
Really, I do. I ran into a snag trying to figure out the gear ratio it needed for the design, so I decided to post it up here looking for help. I do most of my calculations using the JVN calc to make it easier, then optimize the ratios for part availability, machining complexity etc.

And yes, I have many other designs posted up here, and yes I put in all of my materials as I CAD my parts, this one in particular is made of 6010 (correct?) alum, and steel axles, sprockets, gears etc. what you saw is what SolidWorks did it's mass calculations from.

Also, i realize this design is completely, and utterly complex. I would not really even consider building something like this. But CAD allows us to dream right?

I agree with John V Neun simplicity is elegance and it works. This is me comming from a team thats made an award winning 8 wd 6 motor 2 speed drive system and a 5 axis arm. I like the fact that its CAD work practice and your asking really vaild questions instead of arguing why or why not this is needed. This is what should be happening on Chief Delphi people. Good work keep it up.
