In short, DPO is not better than PPO. This is because DPO is derived from so called BT reward assumption that pairwise data preference is collected. Through mathematical formulations, you can learn the preference and the action at the same

Very cool. Robots are edge centric at this moment but 5G and other technologies might enable the cloud applications such as https://github.com/BerkeleyAutomation/FogROS2 .

Agree, aerial vehicles are slightly better than maritime vehicles in this sense. I left maritime robotics because I couldn’t find any decent paying job that is not defense related :( What we can do as a student team is to open-source it.

I can understand the concerns of the technology might be abused in DoD but I should point out that it is much better to see this result on Science Robotics, TRO, ICRA, and IROS etc. Military is behind many technology innovations but this do

This is a hybrid Remote Operated Vehicles (ROVs) and Autonomous Underwater Vehicles (AUVs). The vehicle can be controlled using a joystick(^1) using a wired connection while operating as a ROVs. 1. https://youtu.be/uXA0AkcrN

Every year we upgrade our autonomous sailboat controller to the latest Raspberry Pi. This year we face a situation to choose from Jetson Nano and RPi 4. Even the decision is hard to made, now is an exciting moment for robot makers.

Maritime and airplane emission is definite an issue after the grid power transferred to renewables. The problem is the low energy density and the variance in renewable resources. I guess for transportation it is more practical to aim for n

I remember the fun time when I hacking into a CASIO fx-82ES. There is a unsolder jumper on PCB that can 'upgrade' 82ES to 991ES which has four more functions. http://www.instructables.com/id/Upgrade-your-Casio

Great business idea. Here is the freshly made AD[1]. Curious to see if there is any business plan follow ups. [1]( https://i.imgur.com/oD50taU.png )

Same curious, it has Python extension but not really close to it.

I assume this situation also holds true for those using LabView to build their virtual instruments. IP wasn't really an issue for us since we have decided to open-source our project to broaden the knowledge of the public: https:&#x2F

Mathematica/Python/MATLAB user. Mathematica and MATLAB do both have great documentation and intuitive examples shipped with their product, however, document your own code using their system is surprisingly hard (compared to Sphinx
