struggling with project

"I would add a simple robotic arm to grab the bottle and place it in the bin. the robotic arm will have grippers. who cares if the bottle is crushed. bingo"

how would you react the loads if your arm is only placed on the surface ?

picking up the bottle would be an ask, particularly with that offset.
maybe lay the bottle on its side ?

could the bottle have a hole in it ? maybe no cap ??

have they run a similar problem before ?

Time for OP to answer some of the questions we posed.

it would require a base that is bolted down.
since a bottle mass is lite. minimal FBD.
forces would be minimal. it have to be able to rotate and swing. requires an actuator for the Jaws. very light construction. will it work?

First, thank you to whoever helps. I’ll try to explain myself more clearly.

I need to build a device (asseble a product by using the components above) that will be able to pick up a full 750 ml bottle of water which approximately weighs 770 grams. That bottle need to be place onto a mini tower which is 20 cm height, 21 cm long and 19 cm width (mentioned in the attachment as “here is where the bottle will be placed").

Let's say I’m standing infront of the diagram I've attached, my device will be place to my right (as mentioned "the model place here") , the bottle will be to my left somewhere within the elliptical area whereever i want to (mistakly wirtten as “recycling bin” instead of "bottle of water") and the mini tower is on upper right.
Let me phrase it like this: pre-experiment - i can put, using my device parts only, something on top of the bottle or even grab it. Then experiment begin by me activating a trigger starts a chain reactions which eventually place the bottle onto the minitower.

So let's break it down into sub-goals:

1. Grabbing the bottle: a. How would you pick the bottle off the ground? b. How can i create enough friction and stability on one hand that keeps the bottle from slipping and on the other allows it later to drop onto the mini tower ?
2. Generating height of just over 20 cm – How would you create a potetional energy? So the second challenge, after i've managed to grab the bottle, is to create a potetional energy of a little bit above 20 cm height. So the only idea i've in mind is doing it by dropping small weight from tying it to my device.
3. How can I create a rotational energy of an approximately 90-110 angle degrees to the right (the mini tower is right to my device)?

I've added some illustration of the bottle and the rubber bands.
I appreciate your helping

Just trying to understand what you are doing.

1. You are not building the recycle bin.
2. You are building the piece of equipment that moves the full water bottle from the big ellipse to the smaller ellipse.
3. You are calling the equipment, the "model".
4. The model must set inside the rectangle.
5. You are allowed to "place parts of the model on top of the water bottle" before activating the trigger.

Assuming what I have said above it correct:

1. Are you allowed to use force to "place parts on the model" in the sense of stretching a rubber band or forcing something to rotate as you place it on top of the water bottle.
2. Is your model secured/fastened to the top of the bin?
3. Does it have to be lifted, or can it be tipped over or slid?
4. Can you baseball bat it into the opening?

For me, all problem solving starts with 2 things. 1) accurately define the problem (this definition should not include a proposed solution) 2) think of ALL ways you could accomplish this REGARDLESS of your specific project criteria.

With training, these 2 steps take about 5-30 minutes in many cases provided no one gets wrapped up in your project specific criteria.

1. Correct i don't need to build a recycle bin . what i do need to build is a device that be able to pick up a full bottle of water.
2. So to be clear I've mistakly written “recycling bin” instead of "bottle of water area". Let's say i'm facing the diagram to my left is the bottle to my right and the device and on the top right is a mini tower 20 cm height where eventually and bottle is needed to be put onto
3. Not sure if equipment is the correct word but what i mean is i need to assemble a product/ device that be able creating physics energies
4. Yes the device is rectangle.
5. Correct so before activating the trigger i am allowed to put something on the bottle or maybe grab it. also if it matter i can put the bottle whereever i want within the elleptical area (mistakly written as recycling bin

1. Yes As long as the bottle stays on its place without moving before the activating the trigger. i can put something on or even grab it (of course only by using the device's parts)
2. The device is put on 2cm height platform so i can tie it to its legs with threads or rubber bands. Just to be clear the device will be place within area the rectangler area which is 16.5cm long and 28 cm width and the ceiling is the height limit .
3. It needs to be lift off the board
4. Not sure what you mean - but generally speaking i can place the bottle wherever i want on the other half of the left board.

My three challenges :
1) creating a potential energy - how can i lift the bottle around 21cm off the board
2) I need to create a mechanism that as soon as one action ends, the next action will begin
3) Creating rotation - my device will face toward the bottle and i need to create 90-110 degrees to the right.
thank you for helping

So just to be clear I need to build a device that will be able to pick up a full 750 ml bottle of water which approximately weighs 770 grams only using the specific components from the list above. Let's say I’m standing infront of the diagram I've attached (instead of "recycling bin" it should be written bottle of water), my device will be place to my right (as mentioned "the model place here") , the bottle will be to my left somewhere within the elliptical area wherever i want to (the whole half side approximatly half of the board) and the mini tower is on upper right which is 20 cm height .
I will just point out that the water in the bottle must not spill, otherwise it is disqualified. I have a total of three attempts.
initially i've thought about making a hole and maybe transferring the water to a sealed plastic container, but the tester is very rigid and as soon as a drop of water falls on the board, I will be disqualified. So I'd rather not take the risk by tilting the bottle or removing the cap.
no similar problem before which leads me to next question if you know a simulator, even with payment, that can simulate the course of the experiment with all the details?
thank you i apprecaite your helping

 

[rb1957]

if you are allowed to bolt it down ... OP has said "placed", which open to interpretation

 

[MintJulep]

if you are allowed to bolt it down

No bolts in the allowed materials list.

There's masking tape and glue.

 

[rb1957]

yes, to assemble pieces together. OP, can you glue the device to the staging area ? (and leave it there to cure ...)

Seems simple enough, a 3 or 4-axis robot with path and acceleration control including a gripper that has a compliant mechanism that is just strong enough to hold the bottle and not strong enough to push liquid out the open top. 3-axis to put it onto a tower, 4-axis to turn and empty it.

With the main requirement now clearly stated, it's off to designing it from materials generally not known for use in doing any of those things and motive sources that aren't known for acceleration control.

Most robots used for this sort of task weight 10-100 times what the payload does and are still bolted in place to avoid tipping.
