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 formulatio…

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 …

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…

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 operat…

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 t…

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…

Ordered a paper version on Amazon UK one month ago. Does anyone get the book already?

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.instructab…

I had a great fun in taking photos using a 3D printed pinhole lens on my Sony A7 II body. Here are some sample images: https://flic.kr/s/aHsmmwzBQg

Indeed, we have a previous team (robotics sailing team) member now working at ASV UK. A very exciting job

We build an open-source sailing boat (MIT license) https://blog.sotonsailrobot.org and we will host World Robotics Sailing Championship this year https://www.roboticsailing.org/201…

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 projec…
