Risk of the Lift?

[cgredalertcc]

This is my personal apology for my "attitude" earlier. Turns out after crunching the numbers lift = lighter than ramp. So drum roll please 1741 is.......lifting!! We'll see how it works. I do have a question. If we were to use honeycomb (the metal used for certain surfaces on comercial air craft) and used glue to attach the skin is that within the rules? As they read it says that you may not use adhesive back tapes, but this isn't tape so I think its legal but I wanted other opinions if you wouldn't mind.

Thanks

remember last years ramp was pretty steep and also made out of diamond plate neither of which are requirements for anyonesramp

IMO, if done correctly, a lift can be just as safe as a ramp.

You could technically have a pneumatic lift that lifts your own bot so another bot can drive undernieth then you could raise your lifting mechanism thus you are off the floor!!!!

Wouldn't it damage the other robot thus no alliance parter would want to drive under you and most offensive teams will have an arm or manipulator that is at least 3 feet high.

Yeah, and the weight issue is a biggie there too...

[kyleg242]

Yeah there's a big risk with that stragedy. This will only work if teams design has a large flat area with no appendages sticking out. Also if your arms were to give before your partner was fully in position the fall could cause huge damage to the front of a robot. Also unless other robots are benching 100-120 lbs...

It is almost going to be impossible to use a lift to elevate your alliance's robots. It is going to be impossible because pneumanic cylinders are not going to give enough force to exert a lifting device.

im pretty sure that the pneumatic cylinders come in larger sizes than they gave us so i think it will be possible to lift other robots with a lift. and i thin the largest size is a 2 inch cylinder.

[mizscience]

Good point. I think many people would overlook the possibilty of being dropped if planning on being lifted instead of the one lifting...

[cgdtgurl07]

if they are planning on being lifted they might design the robot so that it can take a little more impact from the bottom (if dropped). But if the lift is designed correctly it probably won't be likely that it will drop a robot. Teams will take the risk into consideration and make it efficient because they wouldn't want to be dropped either.

Thanks for letting out our secret!!!! Just kidding... At first our team went unanimously for the ramp, then the vote flipped and I was stuck on the ramp. Now, well I still think a ramp is going to be lighter, safer, and easier to build, but a lift does have its advantages. So I guess it's official that our team (1741) is lifting...

For those that are lifting and for those that plan to either climb or be lifted, I believe that the lift is much more dangerous. Although with the ramp you have to to keep it in your base and with 2" of clearance due to bumpers you will need to have a small angle thus a longer ramp, it is much more safer. Your robot is always on solid ground. With the lift you are in the air. Are you sure 30 points is worth the risk of your robot falling twelve inches off of the ground? Although I hope this never happens, I think before teams start thinking of being lifted that they should all consider the possibilities both positive and negative. The main one is a robot falling, and today when my team was discussing this I thought of the fact that if you are being lifted up, you are no longer in control of your robot, and that if anything happens your robot will fall. What if it does? Will your team build a more robust robot that can take a twelve inch fall? Will your team prepare for a worst case scenario?

Before you answer keep in mind that six hard weeks of planning, designing, and building went are going to go into your creation.

hi my name is Matt and I think that if you have 1/3 of the robots w/ramps that they will be more valuable than others. I also think that if you have a bot that can be like a tank or a blocker and or some how create a robot with a arm that sits stationary in between your rings and the spider rack and with a pivoting arm meaning that if you create an arm that rotates 180 to 270 degrees that I think would also be valuable

In 2004 team 1141 had 4 pneumatic cylinders (one at each corner of the robot) that lifted them 1 ft so that their 9ft arm could grapple onto the bar. This allowed them to make it geometrically impossible for the robot to not be high enough. So the stock pneumatics CAN lift a robot.

Cmon man you gotta put up a better argument than broad statements like "its almost going to be impossible..." or "im pretty sure..."...If you think teams cannot be lifted with pneumatics, you might wanna scroll through CD-media back to 2004 where quite a lot of teams used pneumatics to lift there 120lb+ selves............VERY SUCCESSFULLY

Get creative...impossible is a dangerous word my friend

[pascoea]

Why are you limiting yourselves to pneumatics? There are MANY more options that would work just fine.

And I would agree, things that were impossible 10 years ago are now old news.

Keep the good ideas coming.
