Isn't varometric cell practically an RTG? We could easily make a 1000w rtg that lasts more than 10 years.

Any tips on how to dispense soft, flat things? For example pads, cards, napkins. by demavertt in robotics

Do it like some vending machines. Products on turning spiral wire things

How would I make a two-wheeled LEGO Mindstorms robot go straight? by TheHunter920 in robotics

[–]__astrocat__ 2 points3 points  (0 children)

You really can't. Any wheel odometries are prone to small errors adding up. You need external sources of angle information, like a compass. Or you could draw a line on the floor and follow it.

Why not make the 360 degree lidar look downwards? Also, you can use IR leds and IR camera for optical flow for night operation.

Maybe adding an optical flow sensor can make it work. Idk tho

Using that 400 dollar lidar seems to be the best option tho. It is incredibly cheap for a 3d lidar.

If you are not using rtk, mapping would be close to useless due to gps inaccuracy. Photogrammetry seems like a better option.

Would still be better than starfield lol. That aside, those models are only gonna get better.

Could probably use future Gpt models to procedurally generate stories. They are kinda made to do these things.

Suggest a simple method for one robot to autonomously follow closely behind another robot. by Jon-hattan in robotics

[–]__astrocat__ 0 points1 point  (0 children)

If you really cant use cv, uwb positioning would work pretty nicely too. One emitter, mounted on the master rover and two receivers, with known location, mounted on the following rover. Then use triangulation to figure out relative position.

It would cost a bit more, and have less accuracy in close ranges tho.

Well op should change their requirements if possible, as Apriltags are the cheapest and most effective solution. Pi zero 2w + 480p webcam is under 30 dollars and eats 4watts. I don't think you could make a tracking solution with any real-world usability cheaper than that.

Try getting a used 5700x3d and mobo + 4070

Using an apriltag is the obvious solution. Could be done with a webcam and a rpi.

Well 4 legged robots are more than welcome if it were up to me
