Glad it was helpful!

Thanks!

Thanks for watching my video! Yes- I pinned this comment because I should have noted in the video that my explanation does not really explain how the RTK receiver deals with the error component of each individual satellite. I was hoping to offer a more condensed "end result" sort of geometric illustration without getting too far into the weeds on the rest. I would encourage anyone who is really more interested in the details to seek out more information from the manufacturers and other online sources.

Thanks for watching my video- Sounds like an interesting project! Honestly I just used the same setup I saw another RUclipsr using because he had posted some incredibly in-depth tutorials on the setup. I am not sure if the ZED F9P was available back when I first purchased my M8P RTK evaluation kit, but I have read up on it a bit since then. I am sure that if and when I ever build an entirely new RTK system, I will try to source a more recent hardware iteration.

To be more specific, I used the M8P evaluation kit because I wanted to avoid relying an an outside correction service- particularly one which would require a subscription and/or continuous Internet connection. With the M8P evaluation kit I am able to set up my own base station and do RTK (perhaps with slightly less accuracy) more or less autonomously, using only the signals from the GNSS constellation itself. I suppose I could set up a similar system based upon the F9P, but I chose the M8P specifically because it included the radios on each unit allowing me to pass corrections from my own base station. From what I could find, the F9P evaluation module has no radios and relies on an Internet connection and a subscription service in order to function. I am really not very savvy on setting up data radios, so I chose the M8P kit because it was already packaged as such. I suppose if I learn of a F9P evaluation kit with radio links similar to my M8P kit, I might look into that.

Check the notes at the bottom of the video for a complete list of the individual components that went into the build. I have not published a schematic or the code just yet. I may cover those in a separate video if that would be helpful.

Hi William. The chip is potted in epoxy and to my knowledge no one has ever been ever to retrieve the firmware. That is why I eventually decided to just build and program a copy of the whole system when I kept coming across the main boards on these Hasbro droids just "dying" for no apparent reason with no way to really diagnose or repair. I also posted a video covering how to convert them to radio control, which isn't as cool as voice control, but it is one other way to salvage a dead Hasbro droid. Check my channel for that video.

Was trying to see if I could fix it but I don’t think I’m going to mess with it. Came across your video tonight while researching the toys.

Basically they play a whole series of interactive games, many with sounds, lights and even motion of the droid. You can search online for a complete menu of commands to test. Also be aware the little LED light in the center of the droid, near the base, is actually a button. It is a sort of safety feature that disables/enables the drive motors. So you might try pushing that button once, then see if you can get the drive motors going. Good luck!

Good question- never really thought about it, but I would assume the Mars rovers derive their orientation either from signals taken from the satellites which are now in orbit around the planet, or perhaps even from signals taken from their associated lander platform. It might also be possible that even though Mars does not have a magnetic field comparable to that of Earth's, it may have enough of a remnant of one to allow for magnetometers to use it for orientation. I have to say, though, that I have never heard mention of magnetic compasses used any of the Mars rovers I have seen, or at least not for navigation purposes.

Hi thank you for your interest. I do not have any close up pictures, but the rotation mostly just consists of a mini-gearmotor such as you can find here: www.solarbotics.com/product/gm18/ which is embedded into the scanner head base, which I had cut in half and machined out to be hollow. The rotation and reversing are handled by the motor controller, and there are no limit switches or any sort of feedback (other than the homing system). The back and forth rotation were just roughly programmed into the Pickaxe microcontroller based upon a set of predetermined rotation intervals (i.e. 500ms right, 250 ms left, 250ms right, 500ms left, etc.) In other words, the rotation control program was written based upon the assumption that the scanner head will always start from the same position it was facing when it deployed from the compartment- so it really has no way of sensing at which point it is in the rotation (again, aside from the homing system which only comes into play when the scanner head is lowered into the dome). - Hope this helps.

Hi again- Just to update on this subject; my goal is to eventually rebuild the rotation system entirely. I think it is just too complex for now, and it has turned out to be not as failsafe as I had hoped it would be. I think whenever I do rebuild it I will try to provide much more comprehensive documentation. Also in case I hadn't mentioned it in the video, you can always search for my threads on the subject at Astromech.net . Not sure if you need to sign up in order to do the search, or you may at least be able to search the builders galleries, which contain folders of the pictures the members have posted. My member i.d. on Astromech is rmeyer.

Any updates?

I bought one like this and I think a kid played with it before I got it and held the head in place so it damaged gears undernate that would turn the head. I want to repair mine too and there are wires torn loose inside the head and I don't know where they go back to.

Hi, I'm Not "officially" an Hasbro/Spinmaster/Jakks technical engineer, but as a great fan of all the SW electronic devices with zero$ budget, I got to learn everything to get all the droids in my actual collection. (i.e. 3 X Spinmaster 16" BB-8, 4 X Sphero BB-8, 1 X Jakks Pacific DELUXE 18" R2-D2, 1 X Jakks Pacific 48" Dart Vador, 1 X Hasbro 2002 like this one, 1 X FX Replica Anakin S. LightSaber, 1 X Sphero Spiderman, 1 X Thinkway Wall-E U-Command, 3 X Anki Cozmo, Stormtrooper/Bobba/IronMan Black Series & Marvel Helmets, 1 X LENOVO Jedi Challenge, 1 X LENOVO dim. of heroes, and few others still to repair.... ) All rebuild from scratch with parts that normally came from 2 or 3 similar model sold on ebay as "spare parts" =) It takes a LOT of times, but I can get what I want for aroud 10% of the avg. eBay price for a "fonctionnal" model in the same condition! Those I listed above cost in total less than 1000$ CAN, they all runs great. If you need informations or have a question, be welcome it's free =) 90% of time it's just a little thing easy to fix!

@@bobleponge8447 Hi! I’m planning to repair my dad’s droid for him. We got the R2 droid a few years back, but when we placed the batteries in and turned R2 on, his head turned to the left and then to the right and died- Im not really sure with what caused it-

Still need the sensor wires pinout ?

@@bobleponge8447 hi, I just saw this and yes that would be nice - think I even called the company and they just said they built them and that was it. With the wires torn loose you just can't tell where they go back.

I will probably always be doing droid related work- it is just not as frequent as it used to be. My wife and I purchased a farm property where we grow wine grapes among other things. It pretty much takes up all my time during the summer months, so that leaves fall and winter for droid projects. I hope to not only continue to do more work on my droids, but to start bringing everyone more up to date on the progress here on RUclips. Making RUclips videos, however, just adds another layer of time commitment, so I will just have to see how much I can put out. Thanks for checking in!

Sensor Array and Telescope? The Interactive R2-D2 only includes a single Periscope. Do you mean the Holoprojector and the Periscope? The holoprojector is the silver knob on the top of his dome, on one of the blue panels, and the Periscope is the two-piece attachment that goes on his left upper dome flap. I believe there are a few listings on ebay for them, but it does cost a little bit. I just recently purchased a replacement door panel, as well as a whole second R2 to possibly do a mod on. I'll take a look at ebay and leave some here. Here's one listing for a REAR holoprojector, but I'm sure you could get it to work in place of the top one. Might take a little gluing, or some fidelling. They appear to be very similar pieces.www.ebay.com/itm/Star-Wars-Hasbro-R2-D2-Interactive-Robot-PART-REAR-ILLUMINATING-LIGHT-HOUSING/382640691688?hash=item59172999e8:g:an8AAOSwanxf~~Fq As for the two Periscope assembly pieces, I'm not sure. Keep an eye on ebay, it'll show up eventually.

The mesh (as well as most of the machined aluminum components) was part of a "kit" more or less that I ordered from one of the builders at Astromech.net . I have been a member of that forum for many years and they have all been a great help to me.

Check the wheel lock button above his third leg. If it is lit up red, he is in a special mode that prevents him from driving off of tables and whatnot. If you press it, the red light will turn off, and he will be free to move. When turned on, it will always start in wheel lock mode.

Mine won't turn on at all haha

@@Yeti1473 Really?? I'm waiting for mine to show up in the mail this week. Are they crap from the very beginning?

@@Evadious-2022 Probably not, I bought mine today from a comic store. It was already out of the box and used by someone beforehand. I'm sure yours will work fine!

@@Yeti1473 yeah that sucks yours is not working properly. I mean I am not going into this blind expected to get a $600 quality lightsaber but I also hope it is not a total piece of shit

@@Evadious-2022 I spent $55 on this without even knowing what it was lol. I just thought it looked cool and I don't have a big R2 yet.

Unfortunately yes- my website was hacked on two occasions. I managed to repair all the pages and restore it back the first time, but then it happened again within short order. I spent some time with my hosting service trying to reach a resolution, but they said they could not help unless I purchased additional services from them. Being that I do not make any income from my website, I had to decline the offer. I would think that a search here on RUclips for "reversing DC motors with relays" or something along those lines might turn up something. Sorry I could not be of any further help at this time.
