Advanced Expressive Humanoid Whole-Body Control

Correcting the correction:

> When you connect 2 9000 mAh cells in series, the resulting battery has 2x the voltage but the same mAh capacity. In parallel, the battery has the same voltage but 2x the mAh.

The relevant units are:

* Capacity (Q, in mAh, Ah, kWh, etc)

* Power (P, in Watts)

* Voltage (U, in Volts)

* Current (I, in Amperes)

* Duration (t, in mostly measured in hours)

And the relevant formulas are:

* P = U x I or Power equals Voltage(difference) times Current

* Q = P x t or Capacity equals Power times duration

From this we can establish that connecting batteries in series or in parallel will not change their Capacity. When having 13 batteries of 29000mAh, or 29Ah, you have 13 x 29 = 377Ah or 377000mAh. Connecting batteries in series or parallel does make a difference in voltage and current: a string in series will increase the voltage while keeping the current the same (theoretically, in practice you get less than the current of the weakest cell); a parallel setup will increase the maximum current while keeping the voltage the same (again, in theory).

Most of the folks on modern AI/robotics paper have Asian names.

It seems Asian tiger countries may lead the next century. They are very hungry to win the solar, battery, EV, robotics race.

Impressive results.

Are there not bigger constraints than battery life to a robot being able to do your shopping for you? It can't drive, public transit probably won't let a robot ride it, it can walk but it'll take forever. If it gets hit by a vehicle while walking, is the vehicle driver even committing a crime? Do you get reimbursed? Is the robot insurable? Do you owe the driver for damaging their car? If it gets to the store at all, will it be let in? If the store allows robots to enter, how is it supposed to pay? Robot's don't own bank accounts, so it has to prove it has the legal ability to use your account. Does this thing have Apple Pay and Google Pay integration built into it? You surely can't just give it cash or your physical credit card and hope that no one notices and steals it. Would a cashier even let a robot use a card that is supposed to be tied to a human identity? How do you authorize that? How does the robot prove it belongs to you?

For that matter, is there anything stopping a person from taking it and factory resetting? I tried to search for both "anti theft" and "theft" on that seller website and nothing came up. Maybe search is just broken for me? These are prominent features of mobile computing devices, cars, generally anything reasonably expensive you might intentionally or unintentionally leave in public unattended.

Apparently the site has an AI assistant, so I asked it. It said:

> Based on the provided context information from Unitree Technology, there is no specific mention of anti-theft features for the robots produced by Unitree Technology. The focus of the information is primarily on the various modes, functionalities, and control mechanisms of the robots, such as Zero Torque Mode, Damping Mode, Seating Mode, Ready Mode, Motion Mode, Standing Mode, Dance Mode, and Debug Mode. Additionally, the information covers services provided by the robots, including basic services, AI Sport Services, Normal Sport Services, Image Services, Network Services, and SLAM Services.

> Therefore, based on the available information, it can be concluded that there is no explicit reference to anti-theft features in the description of the robots produced by Unitree Technology. For detailed information on any anti-theft features or security measures, it is recommended to consult Unitree’s official resources or customer support for more specific details.

In typical AI fashion, that's an extremely verbose way of saying "no, there are no anti-theft features."
