Is this legal???

I am not finished with this. I was just wondering if the “fingers” would be legal during inspection?

I don’t think we can see the picture…could you try attaching it as a file?

Please attach a photo or provide a proper link. Thank You

Is this going to be considered legal during inspection? I am concerned that the “fingers” will now be allowed.http://imgur.com/qOYpiOP

Id personally make them a little less sharp and deadly looking.

Not offering an opinion, but keep in mind that just because someone on ChiefDelphi says it’s legal doesn’t make it legal. Don’t bank on your inspector having the same opinion. Take everything here with a grain of salt.

7

Would it help if I wrapped them in either gaffers tape or electrical tape?

8

Apart from the various sharp edges (which I recommend you take a deburring tool and a file to), you’ll find your answer by reading through the manual.

I would recommend this as well rules are our friend, albeit an unwelcome friend that invites themselves over to your house. Better safe then sorry I would take off as mush of the points as you can.

My team is doing something similar :stuck_out_tongue:

R06 says “Protrusions from the ROBOT and exposed surfaces on the ROBOT shall not pose hazards to the ARENA elements (including the GAME PIECES and excluding a Team supplied ROPE) or people.” I would probably make them less sharp ::safety::

Thank you I was just looking over the rules when you posted.it was 2 pages over.

I have a few questions aside from the legality:

  1. Is it just me or are you using an AM9015 on one side and an AM775 on the other side? Those motors have very different specs so you might consider trying to match the motors (switch the 775 for a more powerful 9015) to gain efficiency and power.

  2. Are those blue things shaft couplers/adapters? What are they made out of? If they’re plastic (which is what they look like), are you sure they are strong enough?

  3. Are you confident in hanging the entire weight of the robot from the two inner .09" aluminum gussets? The gussets holding the motors should not be taking any force because that force would have to be delivered through the gearbox output shafts and planetary gearboxes do not like tangential loads on their output shafts. Did you consider doubling up the inner gussets for extra strength?

  4. How are the teeth attached to the shaft? Are they clamped on? If so, how much compression are you using to clamp between the plates? My team is also using clamping to attach to the climbing shaft and we are using ~.1" of compression/bending of our plates IIRC.

14

In addition to this, make sure that, however you mount this climber, that the bottom plate doesn’t flex. That could also put all sorts of loads on the output shafts of the gearboxes.

15

No it is not legal to use a AM775 at all this year. That is most likly the reason that AndyMark discontinued them or vise versa. R32 is the pertinent rule.

16

They look just like 3D printed couplers to me. I would assume they’ve tested the design with weights.

17

To answer a few questions the blue things are 3d printed adapters printed with 100 percent fill. I will check on the motors gearing. Thant you for the idea of doubling up on the musettes as I will probably be implementing that. I did not measure the amount of torque seeing that all the plates are doing is grabbing a not and holding the rope. Even if they aren’t perfectly tightened they should be able to serve their purpose.

18

I’m thinking for torque on your hooks will be fine, we are using coat hangers.

19

Has this assembly not already been tested with like weight plates or a filled box attached to it?

Thank you for pointing this out I will switch it out with a 9015
