They have a partnership with my gem 💎 PDYN \[Palladyne ai\] This will offer to their respective customers the bundled solution of Palladyne AI’s Pilot autonomy software for uncrewed aerial vehicles (UAVs) and Palladyne’s IQ autonomy software for industrial robots and cobots combined with Mobilicom’s OS3 (Operational Security, Safety, and Standards compliance) cybersecurity software. “We’ve partnered with Palladyne AI to deliver a powerful software solution that is critical for mission success, whether that be on the battlefield or on the manufacturing line. A unified solution combining the strengths of our platforms will deliver unprecedented autonomous operations securely, protected from hostile threats, even in the most challenging tactical settings,” stated Mobilicom CEO and Founder Oren Elkayam. “We have already identified a number of our current customers who have expressed interest in putting the capabilities of the bundled product to work.” “This collaboration agreement with Mobilicom’s OS3 cybersecurity allows both of our companies to offer a highly differentiated, best-in-class bundled secure solution for AI-driven autonomous hardware systems,” said Ben Wolff, CEO, Palladyne AI. “The combination of products provides enhanced performance and threat protection for both companies’ current and prospective customers.” Palladyne Pilot scales the operational effectiveness of tactical UAV missions through enhanced human-machine synergy and by transforming UAVs into autonomous collaborative assets by enabling persistent detection, tracking, and classification of objects of interest by synthesizing multi-modal sensor fusion data in real-time. Palladyne™ IQ for industrial robotics uses AI and ML to provide human-like reasoning capabilities to perceive and adapt to changes in the real-world environment, making robots smarter and ready to handle jobs that have historically been too complex to automate. Mobilicom’s OS3 provides groundbreaking cybersecurity for next-generation AI-driven drones through continuous monitoring, detection, alarm, and prevention of threats during the entire mission. Its multi-layered architecture implements advanced intrusion detection systems (IDS) and intrusion prevention systems (IPS) that prevent tampering, data theft, and unauthorized access in real-time. Designed for complex operations, OS3 enables continuous resilience through proactive threat detection and automated response while ensuring regulatory compliance.

Seriously, UMAC RCAT PDYN ONDS these drone companies are seriously undervalued and the move literally just started 20 minutes ago. Another huge drone announcement. Literally the easiest 5x at least over the next few months. I don't spam this is real.

ONDS, PDYN, DRO, SYM, SMI are the ones BTW

QS — 10x in the next 18 months is not too crazy goal (Jan 2027) if it hits all its milestones; BKSY — 3x in the next 18 months is reachable, which is only the same mc of PL. PDYN — a bit speculative, but I feel hopeful because if it’s CEO

I’m expecting PDYN to be acquired

Mentions:#PDYN

Well for starters, the company exists since 1983. Started with automatons in Disney. At one point Raytheon (major defense contract player) bought them. And they later bought themselves back. They are a known entity within the defense world. And it's a company with a lot of know how. Hardware, robots, exoskeletons..they made it all. Coupled with their own software. Never had any trouble attracting impressive management. Laura Peterson was the CEO (known from Boeing). Then the original CEO came back and the company transformed to Palladyne AI. They let go of the hardware component and now make software independent of hardware, which is an easier sale. They found a way to train and retrain robots without coding or engineers. Making it very adaptable, and making it possible to repurpose robots.(think of those robots that build cars, and can be repurposed for a new model) Since then insiders have been buying consistently, as well as an external investor that filed with the sec. Their company Presentation shows potential uses, based on customer discussions..so they are already in extensive talks. They have added management from Delta Airlines, iRobot, ABB to produce more sales. And recently added a board member from Caterpillar. They presented their Palladyne IQ product at the Automotice Circle last year.. IQ is for non-aerial robots. They also were working on their second product: Palladyne Pilot for aerial robots. And they partnered with Redcat for those. They have now partnered with Mobilicom for security solutions. From the Sarhan interview with the CEO: Focus on ALL robots. Annual licensing per robot basis. License is 35 000 USD - list price On top: small computer box that has the software (so for the IQ product) - one time upfront cost. TAM: 500 000 industrial robots each year - adds to million of robots that are already in place. PDYN can retrofit existing robots and help sell new robots for applications ppl didn't think they could be used for. 500 000* 35 000 = 17 500 000 000. I expect truly great things from this company.

Use Reddit to find small cap companies. Then investigate those companies and see if they are competing against other companies and/or if they have attained contracts. If they have and the company hasn’t boomed yet, then great. Determine how much you want to invest. P.S. drones are becoming big now. UMAC, RCAT, PDYN, ONDS are public stocks that you might want to look into. I’m sure each one has their own subreddits.

Is this why RCAT and PDYN have been ripping?

PDYN - Palladyne Ai… gives robots the ability to observe, learn, reason, and adapt quickly because it doesn’t relying on the cloud. Multiple partnerships already in place.

I know this isn’t considered a Pennystock anymore, but it just was in December. Is anyone looking at PDYN (robotic company that uses Ai to enable robots to observe, learn, and reason within their environments). Currently trading in the $7.50 range. Plus they just did a multi drone collaboration with RCAT.

Mentions:#PDYN#RCAT

RCAT is about to blow the top off. It’s a US military drone company, still over 50% down from its 52 week high. After the Ukrainian drone attack, the world will wake up to how important drones are. Also 2 Executive Orders on US drone manufacturer being singled this week. Get in and thank me later. PDYN also a great AI drone play will follow suit.

They do run their physical AI solution on Nvidia chips, but also qualcomm. Beginning of the year they started migrating the software to a next-generation, U.S. made AI computing chipset for the Air Force. I wonder if it's the Blackwell chip. They are produced in Phoenix. And Jensen has been talking about Physical AI as the next chatgpt revolution. Which is exactly what PDYN does.

People on reddit seem to have an avoidance of locking in profits. I locked and took profits on RCAT, UMAC, OPTT, PDYN, BBAI, GRRR. The only one that I didn't lock in profits on, was ASTS. Gave me a $6-7 loss per share.

I have some notes here, IONQ, NUKK, PDYN, even NVDA, RGTI, even RYCEY. There are a lot more, but some are not pure plays, but off to the side plays. RYCEY for example has done well for me, but I got into them for their modular reactors; as a solution for power, and AI and quantum compute uses a lot of power..... dadada. I feel fine investing a bit here and there with the current decline in the space; don't put all your eggs in one basket, but these eggs have started to get cheap compared to IRL!

I’m probably invested in most of these companies…$RCAT, $UMAC, $ONDS, $UMAV, have invested in $UAVS too. Besides $RCAT and $UMAC, I think $ONDS has the most next best potential (or even greater actually). I think something is suspicious with $UAVS so that probably means it’ll go to $100. $UMAV is the most intriguing to me and I have a pretty sizable position at this time (over 15k shares). You will hear just as many people talk shit about $UMAV as anything, because there’s just not a lot of news about them. It’s a speculative play, and one I want to be involved in. There’s also $DORO and $MOB in this space, and $PDYN and even $PRZO could be considered players in the UAV space.

r/pennystocksSee Comment

$SOUN and $RZLV are the correct long term AI software plays. I’m actually happy $NVDA exited their $SOUN (and $SERV) positions. It was creating too much unneeded volatility for those two stocks, that have legitimate long term potential in their own. It made me think of the $PLTR investments in $RBTC, $MSPR, $SRFM and $PYDN (those come to mind) and how it took $PLTR exiting the $PDYN position for that stock to come into its own. I feel $SERV has gotten too much attention, especially as a guy that likes the long term prospects of $RR. I think this is good for the market. Let these companies survive on their own!

Waggs I love you man. So, Joby sits at a higher valuation but you don't have an issue with that at all which is my main issue with your anti-dd. LOL, it's all good but why can Joby sit way up there but not archer? I don't get that. 1. They are more than likely probably ahead of Joby. 2. They have a high volume manufacturing facility already up and running. Joby does not. 3. The hybrid-propulsion engine system with Anduril is HUGE HUGE. That's going to be a hell of a contract. Anduril is valued at 14 Billion and is probably worth 20 Billion. When these things take flight and are commercialized with air taxis and militarized for the military use Archer is probably valued at a future rate of 25 - 50 Billion easily because of the volume. Of course that is the future but if anyone solves the transportation mess that we currently have in a meaningful way that is virtually priceless. When Archer builds the hybrid-propulsion aircraft that too will be commercialized for longer than short haul trips. Short to medium hauls if not even longer. They reported drones in New Jersey being up in the air hovering for over 6 hours straight. That's not battery tech that's a hybrid propulsion engine. The new world is coming and Archer, Joby, Beta, Rklb, LUNR, PDYN, RCAT, PLTR, Anduril they're all going to prosper.

They are overvalued but they are a defense play. https://tealdrones.com/press_releases/red-cat-begins-integration-of-teal-2-drones-with-ocean-power-technologies-maritime-surveillance-solution-for-air-sea-and-subsea-defense-and-security-missions/ Since the Teal 2 drones won the Army's SRR program of record, they will get to ride the wave with RCAT and PDYN. I agree with your other points, but I do think swing trading this is possible because of the Teal 2 drones. Like a 0.64 to 0.94 swing. There would have to be some crazy pumping or actually profitable contracts for it to hit over $1. We might get news of some crazy big Teal 2 drone orders that use OPT Domain Awareness to protect the Gulf of America, but I just don't see that happening soon. (NOTE: I didn't have much faith in OPTT and sold my share before it hit 0.94. Doubling my money was good enough.)
