Had some questions on this skill. I did not see any configuration for which motors to use. If you've got multiple motors running how does it know which ones to control? At present I think it can only be configured for one start positions and one final position, would think that it would be better to make it similar to your movement panels whereas you have multiple actions and frames. Over time multiple configurations will need to be written for different movement between locations, it would be nice to save them within the skill itself (maybe it already is but I can't find it)
Here's a video on how to use the better navigator.
Yes, I saw that and it’s great. I think I may have been the first one to post on it just working out things this morning it’s very close, will get back on it tonight after work
Nice video DJ. It Just turned up in my LinkedIn feed. I was wondering that now all you need is the Lidar on board and not expensive realsense if the entire thing could be offloaded to an arduino so we don’t need an on board SBC. Went to buy a Pi 4 for cyber Monday and it’s cheaper to buy a laptop. If you hang the Lidar off an arduino you would reduce power consumption and cost and you don’t have to drag an SBC around.
We used to have that with our first experiments. The trouble we ran into was latency with the slam algorithm. Any latency at all warps the map and makes it unusable.
there’s a number of reasons benefits to onboard sbcs, which is why it’s the direction we have been taking. What you can do with remote wifi has been achieved and pretty much maxed out.
Also, the Intel realsense isn’t being used in that video. Just happens to be there because I use that robot for a number of tests.
A raspberry pi makes a terrible sbc. It’s capable but super slow compared to the alternatives.
I’ve been using these Belkin sbcs that are less then $200 Canadian with 128gb storage: Mini PC, Beelink Mini S Intel 11th Gen 4-Cores N5095, Mini Desktop Computer 8GB DDR4 RAM 128GB SSD, Mini Computer Dual HDMI 4K UHD/Gigabit Ethernet/Dual WiFi/BT/VESA for Home/Office https://a.co/d/bzEKRNN
Thanks for the tip on the beelink. Gone are the days of the sub $100 SBC. I ended up not buying anything. I have a NUC and 2 Rock PI X but they are all in bots so I guess I’ll repurpose one. Ok I understand the latency issue. If your bot is not where it says it was when it took the reading things would drift. When we can have ultra light SBC and LIDAR on our Drones will be cool.
That drifting was the death of me, haha. I kept pushing the wifi method because, at the time, I was at EZ-Robot, and it was our product. But now, with Synthiam and being hardware agnostic, I get to support whatever is best for the job. Sadly, the cost increases as you get into more advanced technologies, like SLAM. I would like to see the hardware price lower because it seems so high lately. There also haven't been many advancements in hardware to get me excited, specifically with SBCs.
