Modeling and Simulation of a Micro-Helicopter in Wind
See projectThis paper describes an 8-DOF dynamic model of a coaxial micro-helicopter flying through
a steady, uniform wind. The helicopter is modeled as a six degree of freedom rigid body.
There are an additional two degrees of freedom contributed to the model by the stabilizer
bar located at the top of the helicopter rotor axis. A simulator using this model has been
created in MATLAB in order analyze the behavior of the helicopter under various conditions. -
Experimental Validation of Wind Estimation Using a Micro-helicopter
See projectAutonomous air and ocean vehicles operating in real-world environments will frequently
encounter flowfields such as wind and ocean currents. The ability of a vehicle to estimate
the spatial variation of surrounding flows is useful for the collection of the flow data itself
and for the feedback of the data into individual or cooperative control algorithms. This paper
presents a novel flowfield estimator and, along with a previously developed estimator,
tests the capability of wind…Autonomous air and ocean vehicles operating in real-world environments will frequently
encounter flowfields such as wind and ocean currents. The ability of a vehicle to estimate
the spatial variation of surrounding flows is useful for the collection of the flow data itself
and for the feedback of the data into individual or cooperative control algorithms. This paper
presents a novel flowfield estimator and, along with a previously developed estimator,
tests the capability of wind estimation under non-ideal conditions. The testing was done
through numerical simulation and physical experimentation using tracking data of a microhelicopter
flying through a fan-produced wind-field. Both estimators are based upon the
model of a self-propelled Newtonian particle in a steady, uniform wind. Each estimator requires
particle heading and position data for all time in order to produce a wind estimate.
For error convergence, the estimators also require that the particle travel at a constant
speed relative to the wind. Behavior of the estimators without the condition of wind uniformity
is discussed. The estimators were tested experimentally, using a micro-helicopter
and a fan-produced wind-field. Measurements of the position and orientation values of the
helicopter along its flight path were taken with an infrared motion capture system. This
data was run through the estimators and the resulting wind estimates are presented and
compared to the measured wind-field. The trade-offs associated with each estimator are
discussed and discrepancies between the theoretical model and the real-world conditions
are addressed. Future estimator improvements and research directions are presented.

Hot take…it’s not like getting into YC is your automatic ticket to success. But there are a few things about it that made a huge difference. 1. It steps up your company’s pace. They push you to move fast, iterate quickly, and constantly validate your assumptions. This creates a sense of urgency that permeates the entire company. This is worth more than you’d think. 2. The advice is top notch. Double is my 2nd startup - I founded Jetfuel in 2016 which was eventually acquired. I wish I’d had all the YC advice the first time around. 3. Raising money is significantly easier. The brand of YC means it’s significantly easier to raise a round than without YC. It’s still hard and stressful, but it is undoubtedly one of the perks of YC. At the end of the day, you gotta do the work yourself. But YC gives you a big leg up.

Today, GTMfund’s is excited to announce to launch of Operator, its first incubated company. Max Altschuler (founder of GTMfund) teamed up with co-founder Adam M. (design engineer and 0-1 builder) and co-founder Mark Kosoglow (Outreach employee #1 and former SVP of Global Sales) to create Operator.ai alongside an insanely talented team Pleasant Middelhof, Jeremy Jonas, Carl Gunderson. We've entered a period called “The Great Ignore”. Spam and irrelevant, poorly-automated outbound campaigns are running rampant. Operator gives you an easy-to-use Growth Engineer that allows you to build and enrich lists with accurate data, and run experiments and queries using AI to generate highly targeted outreach. Check out their website to get updates, early access, and see how they are taking the world back to 2 touches meant to attract buyers into conversations that convert, instead of 20 touches meant to make sure you hit your activity number: https://www.operator.ai/

The founder of Substack posted about payment systems, platforms, and Patreon: https://buff.ly/4dG8LJ4 I think this candor highlights several inconvenient truths for startup founders: 1. Even if you create the most frictionless, user-focused, and ubiquitous piece of technology (like the App Store in this example), some users will still dislike it. They may criticize you for building such a great product, viewing it as too dominant or monopolistic. 2. After building a successful product, you must continuously provide value to justify your fees, existence, and market dominance. You can’t simply create something valuable and then rest on your laurels. 3. There will be all types of unintended end users who rely on your product (like creators in this example). You can't anticipate their needs, but you'll have to accept the responsibility that come with supporting them. I can only hope to build products that become so prominent. The closest I’ve come was when I managed referral amounts for US/CAN UberEats couriers in 300+ markets. Our Supply Ops team took this responsibility seriously, as the payments directly affected the livelihoods of our users. We paid millions of dollars each quarter to accelerate growth in earning opportunities. Even if these were bonus amounts or part of a value-add, they still drew significant scrutiny. Building products that people rely on every day for their income can be a magical experience. At the same time, it’s a serious responsibility. # FounderLife #Platforms #UberEats

Synthflow AI recently raised a chunky seed round of $7.4M. Their pitch is that their no-code platform makes it easier than ever for SMEs (which usually have low tech capabilities) to deploy voice agents for a multitude of use cases. And they do have a pretty good flow builder. At Hooman Labs, we too are striving to make voice agents as simple as possible to deploy. But we believe that while self serve is important to enable users to play around with voice agents, it is more critical to build a suite of plug and play agents (including necessary integrations) which don't need a lot of tinkering by the user. To do this, a voice agent provider needs to go deep into a vertical and understand the workflows of their user, end to end. We're doing this for e-commerce and building agents which solve calling needs of brands across the life cycle of the customer, from pre-sales to post. Some of the use cases we're working on are consultative selling, delivery updates, abandoned cart conversion, return requests and warranty claims. If you run an e-commerce brand and are looking to automate your calling function, would love to talk to you and understand how we can help. Tarun Rathore #voiceai #conversationalcommerce #ecommerce

This last weekend my brother Arthur Zey and I just finished the "Improving Your Product Sense" course by Shreyas Doshi. Unlike most courses that aim to give you specific tactics, frameworks, and processes to use - this week-long course aims to improve the quality of your thinking and arm you with different mental models and perspectives to make better decisions. By that score, I consider the class a resounding success and I'm eager to apply our insights to sharpen up our strategy and product definitions at RP Strength. If you're a founder of or senior product manager for a software company, I think you'll get a ton of value out of the course. Check it our here: https://lnkd.in/gENYXyTJ
