  Hey, so the problem with your soldering is that you're trying to solder a thick copper wire held with hot glue. Since the copper wire is so thick it needs a lot of heat to overcome its heat capacity, and reach the solder melting temperature, and before then it's already hot enough to melt the hot glue again. Next time try with thinner wire (I usually use the leads cut off from used through hole components) that can heat up more quickly locally, before the temperature reaches the hot glue.

  That makes a lot of sense! I turned the heat up and down for certain parts, but different material would have been the play.

  Yes, if you already have the correct version of Gazebo working with the corresponding version of ROS2. Although I've had issues with Gazebo in the past and have given up on it, I would like to try it again in the future.

  Nice video. I have one question about the code to control it. So, we have a publisher (laptop) and a listener (RPI). Is the entire code stored on the development machine? If not, do you write the code via SSH to storage at RPI?

• 
  @hackertwins3 ай бұрын

  The code is both on the Raspberry Pi and my Laptop, its the same exact code too! It works because both machines are running ubuntu OS with ROS2 installed. Here's the repo github.com/doeswork/stepper_motor. Both my machines are set to listen/talk to nodes over the network `export ROS_LOCALHOST_ONLY=0`. I go into a bit in this video where I install ROS2 kzread.info/dash/bejne/pWt4s7KFY7nAlso.html

  @futureengineer26433 ай бұрын

  ​@@hackertwins Ok. So, if I understood you correctly, you develop your code on the dev machine (laptop). Next, you push it to GitHub, and then you clone/(sudo apt update -> sudo apt upgrade) the repository to RPI. Next step is testing (check sensor values(gpio) and control actuators). Does it look like what I wrote?

  Awesome! I am stuck at the "waiting for images". I can see that the terminal outputs "one frame has been sent" but nothing appears on the actual orbslam viewer. It worked 1-2 times and since then never again. Any idea what might be wrong? And is it necessary to adjust the TUM1.yaml file at all to get some first results?

  Ever so slowly move your camera on startup, it needs to build a 3D space before it opens the map

  Thanks for answering! Unfortunately this also doesn't help there is still only a black screen and it keeps saying "waiting for images".

Do you have any other possible solutions? Thanks a lot. @@hackertwins

  The shape and movement almost look like a cartoon gorilla. The velocity of the servos on the outer legs seems slower in comparison to the outer legs. This difference may cause the gait to be off. I'm glad to see progress. Keep it up!

  Very cool! I always love looking for new projects. One question, though: I just built an RC car with a Raspberry Pi controlling the outputs. I encountered a similar issue with the servo twitch. Do you have any ideas on how to fix that? Thanks for the inspiration!

• 
  @hackertwins4 ай бұрын

  Usually its a bad universal ground connection, or not enough power. Check that every negative wire is connect to each other. Next add more power, even if you have to plug it into the wall just to test. Then probe voltage during operation and see if you are getting a voltage drop on the PI. You might need a capacitor or buck converter to keep raspberry pi voltage consistent.

• 
  @berardinux4 ай бұрын

  @@hackertwins Cool! Thanks for the info. I just added a 100 uF capacitor to the circuit and that did helped with my issue. I think the spike in current is dropping the voltage through my buck converter.

  I love this, I just got back into robotics, and this is inspiring! I agree that batteries and wires could be moved to contribute to center of gravity. Traction pads could help. But I absolutely love to see walking robots of any type. Most, myself included, go straight to wheels; nature didn't, so it's inspiring to see walking bots!

  ORB SLAM3, as well as other stereo camera SLAM systems, have some practical advantages over LiDAR. LiDAR typically generates 2D maps and might need extra sensors for complete motion tracking. On the other hand, ORB SLAM3 can function with just a (stereo) camera and create 3D maps, which can provide a more detailed understanding of the environment. Check out our new video were we unbox an Intel D435 Stereo Camera and record in 3D!
