World's highest jumping robot

09/04/2022 10:22 AM

Here is a link to the World's highest jumping robot.It uses a unique means of storing energy and releasing it suddenly.

Imagine this principle in a bow,slingshot or Trebuchet?

Compound bows and crossbows use a form of energy storage,but could it be improved with this principle?

Fascinating. I bet this thing could really jump on the moon!

150 meters high,500 meters long.Per the video.

Don`t think so. First, they need to invent elastic bands that will not burn on the moon, then they need to isolate all the moving parts from moon dust - regolith, because as soon it hits the ground landing, it will blow up a lot of it.

You might have a point. I understand moon dust is like statically charged ground glass, nasty stuff!

It may stir up a lot of dust,but it will not "blow" anything up.

There is no rocket motor.

It will settle rather quickly compared to Earth where there is wind to scatter it.

The static charge can be eliminated by applying an alternating electric charge to the equipment.This method is widely used by industry to control static charges.

You're probably right that as this robot is presently built it would fail on the moon. Then again, who said a moon version using this principle cannot be built someday?

It may be possible to engineer a variable rate spring with similar characteristics as latex,maybe even better.Of course,to flatten the curve,it woulds have to match the carbon fiber also,so they would have to be sized accordingly,and their profiles would have to be adjusted to get the max out of the configuration as a whole.

So, how to improve it to obtain even more velocity, height, distance? Rather than scale everything up as suggested in the video, keep the carbon fibre and elastic structure the same size but instead of one, stack two or three of these structures one directly above the other. Cord tensioning and release mechanism the same as shown but now shared. The desired force curve would be maintained but the force would be applied over a greater distance for a longer time, and the assembly would still collapse into an aerodynamic shape upon launch.
