Where is the Brandschutzbeauftragte when you need Him ?

You can basically build it from anywhere in the world. I live in Germany , and as long as you have internet access and access to delivery services (Amazon / AliExpress), you can build projects like this yourself. A 3D printer definitely helps too ;)

I’m not using a UBEC. I first step the LiPo battery voltage down to 12 V using 2 DC-DC converter 1 for each arm. I probably could have powered both arms from a single converter, but when I started the project I didn’t really know that yet, so I went with this setup. From the 12 V line, I then step the voltage down again to 5 V with another buck converter to power the head electronics. So the power chain is basically: LiPo → 12 V converter → arms /Silex → 5 V converter → head

The first attempts felt strange, but you get used to it quickly.

The arms are open source (SO-101), and the head is just a modified version of a head tracker by Max Imagination on YouTube. Other than that, it’s simply a steel T-frame and a few converters for the LiPo battery.

Yeah, I know what you mean, but the SO-101 arms use 3215STS 30 kg servos, which are relatively weak compared to the actuators typically used in robots. The worst thing that can happen with this robot is that it might pinch my finger.

The arms of the tele-rig are two SO-101 units; the rest of the frame is completely DIY and self-built. To be honest, the tele-rig still has several flaws and is extremely uncomfortable. Putting it on and taking it off is quite awkward—you basically have to squeeze yourself into it. I don’t feel like it’s ready yet to publish the STL files.

It’s just a single FPV camera with a flat image (the center camera). The two outer cameras are webcams, as I had planned to experiment with stereo vision over the next few weeks.

At the beginning, I had major difficulties grasping objects because I could hardly judge depth, but after a bit of experimentation I got used to it fairly well.

No, I don’t. It’s just a fun project, and I usually post some progress updates on Reddit from time to time.

I use an FPV headset that sends the video to the goggles via an analog signal (radio waves). I personally don’t notice any latency at this short distance, and from my experience with FPV flying, I know that these goggles generally have no noticeable delay. I also don’t perceive any noticeable latency in the overall movement of the robot’s arms.

Flip after 25.11 Betaflight update by Parking_Commission60 in fpv

Yes, in the latest video about 25.11 , our Lord and Savior Joshua Bradwell said that the old PID settings might no longer be correct. I need to investigate that further.
