# Chinese Robots Worlds

Does anyone have pictures of the chinese middle school winners? I would like to see pictures of there scissor lift? Also could someone explain there scissor lift because it looks different from other scissor lift designs?

Here is a rough sketch.

The Green gear is attached to the blue bar (but it can’t rotate). Then the gray gears are attached to the red bar (but they can rotate). Also one side is fixed at the bottom and the top and the other side could slide.

Is the gray gears connected to the blue or red bar?
So basically since the green gear is fixed that means when the gray gears rotate they rotate around the green gear in place. Thus leading to the bars raising like a scissor lift, but not like a corperalchee scissor lift?. Right?

Yes, the gray gears would be powered directly by motors on the red bar.

The corperalchee one has little lifting force when the lift is at the bottom, but a lot when it is higher. This one maintains more constant force.

Is there a name for this type of scissor lift? I don’t want to sound dumb when I report this to my team. I want them to learn/know the name of this type of scissor lift?

How fast is this type of scissor lift? Would the speed correspond to gear ratios or not? For example if I had 12 tooth gears motorized, and a 84 tooth gear that is stationary will the speed be like an arm geared at 1:8?

First question, its just a scissor lift. i suppose you could say its powered through spur gears rather than a linear slider.
Second question, youre getting the same torque as a 1:7 ratio but its applied through more joints i believe. by the way, 12:84 is 1:7, not 1:8.

We built this scissor lift, and it works well and fast. The only thing we are encountering are gears skipping the same thing with our claw.

How could we prevent the gears from skipping? We added free spinning gears, and made sure everything was tightened.

This can happen alot if you are not careful we also built a scissor lift like the chinese from gateway it was just a model but we encountered these problems aswell what we did is added an extra support bar to the opposite side of the moving bar(the red bar from the previous example) This bar was more secure after that and the drive shafts had no where to go so it stayed perfect we are now currently building our full size scissor lift.

Well any questions just ask and if info on the chinese scissor lift please provide

Thanks

How does the other scissor lift robot not 8192 work?
When I mean by work how come the top of the scissor doesn’t have to slide like 8192.
How does the scissor lift attach to there scoring mechanism?

I’m not sure which robot specifically you’re looking at, but any robot with a scissor lift needs to have pieces that slide when attaching to the robot and the intake platform. The lift can be made such that the intake platform stays directly above the robot or so that the intake platform moves out while the lift raises.
It’s looks like both robots with scissor lifts keep the intake platform directly above the robot by securing the lift on one side of the robot and allowing it to slide on the other side.

You can both of the robots’ lifts raising/lowering here.

The one with the center grab in blue?

The red robot or the blue one? The red one has a claw and straps with standoffs for the scissor. The blue robot with the needle has what looks like c-channels for the scissor. It’s hard to tell how the sliders work, but at the end of the video it looks like the red robot has slotted angle pieces, and at 36 seconds I see linear slides on the blue robot.
