Elevators/ Forklifts

[Rick TYler]

Remember that the lifting apparatus can push against the floor directly underneath the robot being raised. There is no need for it to be a completely cantilevered structure. Think "automotive floor jack" instead of "forklift."

[zander_108]

Yes. That is exactly what i was thinking. It is to have a sicssors lift that is completly self supported from the ground. This means that in will be able to lift the robot relitivly quickly with the right set-up .

The presentation titled "Designing Competitive Manipulators: The Mechanics & Strategy" offers some details into how to possibly build an elevator.

There are more pics on the robonauts website here if you are interested and there are some videos too.

Thaks for everyone's help and especially team 118 for the photos. I looked more into the 2005 robots and saw that wildstang's and team 64's forklifts were the kind we would want to build.

Also this elevator is used excusively for picking up INNERTUBES and not robots.

A regular nylon strap is light and can lift quite a bit of weight. We used it to telescope our 15 pound arm. That was back in the days of the Van Door motor...

what about using pneumatic pistons how do you think they will work

We're looking into it [Team 168]. The only problem is that they weigh so much.

[agndoggieboi]

Our team made an elevator for the 2005 competition. You can see the pictures on our site, www.mckinleyrobotics.org and go to the 2005 website link.

One of our off-season projects involved making a lazy boy into a moving robot with pneumatic lifters...lets just say that was the inspiration for our manipulator this year.

This Question is referring to the concept of having a component push against the ground and raise the robot.

According to <G56> "Robots score bonus points at the end of the match if they are entirely in their HOME ZONE, not in contact with any element of the field (carpet, alliance station, goal, etc.) and the lowest point of the ROBOT is higher than 4 inches and/or 10 inches above the carpeted field surface."

So my question is, can you have an entity on your robot push against the ground and not qualify as being the lowest point of the robot? Or are there some special circumstances?

Thanks.

That rule is referring to a robot that is being lifted by another robot. So the robot that is being lifted can not come in contact with the field and its lowest point must be higher then 4" and/or 12". But the robot that is doing the lifting can and will come in contact with the field, unless your robot has an anti-gravity machine.

If you can do that, you will:

a) have a very good chance of winning the Championship
b) have a very good chance of winning a Nobel prize, assuming you manage to get the credit.

try this link for a really quick rundown of folklifts. There's a really nice picture there to get the brain moving. Just trying to figure out where we can get, or produce cheaply, the rails/tracks for something like what's on page 14.
