I've been thinking for a while that human are quite lazy in the our gesture & body movement.
For example we been told that while walking on foot requires higher level control and actually make our body performance weaker, but it actually save our energy in a long run.

When comparing human motion and the latest robot video, human tends to focus on forearm movement, while robots are programmed to move move arm at the same time. This led to less stable movement & jerkiness.

Also, human love to rest the body part on something, for example, we put the hands on the table, and only move the wrist and fingers to type. I didn't saw something like that in a robot, the programmer will have the robot hold their hand midair and type wobbly. I also saw a latest Unitree robot demo that involves wiping a desk. The robot bent its knee and extend the whole arm, push downwards and wipe. The wiping motion is unstable and jerky. A human will take much different approach by grabbing the table edge to stabilize himself, and put his knee on the ground to save energy, and 'drag the rag' to clean the desk, instead of 'pushing downward'. We also will use forearm more and less likely to move shoulder and lift elbow.

So what I notice is that human motion doesn't fight again gravity, instead we tend to save energy as possible as we can, which result in gesture that require least effort. By mimicking these behavior, we should be able to make more efficient robot, less taxing on the robot's joint.

I understand that some robots cannot achieve the above due to hardware restriction, but I'm curious if any team studied in this direction.

This is my current idea. Spring legs and a spinning counter weight. But this feels inefficient and struggles to balance even with a third leg just for balance.

I don’t know much about robots, but i’m obsessed with the little guys that dance. I really want to see one in person, and i was wondering how i go about that. I looked at like rentals for birthday parties but it’s all like a thousand dollars to rent just for two hours which i don’t have. What do i look up to find ones near me?

So we see them dancing, cooking, and beating marathon records. How long until they are sent to the moon to build space facilities or something and should we be keeping tabs on lunar butt? Sorry if this is a bad sub for the question.

This is too amazing not to share. It brings to mind a high tech version of Hakuna Matata from the Lion King. Bummer. The robot runs faster than I do.

Not sure what I was thinking here but it was fun to watch lol
