BADDY - Open Source Badminton Robot!
Inspire and enable everyone everywhere to enjoy badminton. Let's GO BADDY!
- Badminton is cool: Everyone loves badminton - Accessible, popular, simple, and blazing fun! It's a sport made of great values: performance, respect, happiness... That's why people love Badminton, that's why it becomes increasingly popular!
- The problem: Badminton machines exist on the market, but are not accessible to every one: too expensive (2.500€ minimum retail price), not portable (it's indoor or nothing...), with proprietary technologies (costly to maintain, restricted roadmap evolution). People who like fun and sports would enjoy such a machine, small clubs would use it for training, but they just can't - Now's the time to do something
The goal and vision: Inspire and enable everyone anywhere to enjoy badminton!
BADDY aims to best serve badminton's core values, to boost the fun of that great sport we all love. BADDY is the first badminton robot for indoor or outdoor use. It is made of latest open technology - We want to provide the most affordable and open platform, driven by the community. We trust this beautiful idea can become a reality.
BADDY is a perfect introduction for enjoying and boosting fun with a badminton robot, but at this point it is very much a product for makers/developers. It's a blast to play with, but you should be ready to tinker with it. The BADDY DIY kit involves soldering, gluing, and wiring of electronics.
Except the current known limitations on the prototype (further detailed), we don't encounter problem with BADDY so far. We have gone through different stages improving design and durability, but we don't have a long experience yet on how the product will behave in the long run - shooting shuttlecocks involves strong mechanical sollicitations on the product parts. The aim of this first Kickstarter campaign is also to get first feedback on users experience, that will nurture BADDY's project future.
BADDY project in a nutshell:
- Cool features: extremely portable, enjoy badminton outdoor, or indoor, control with an app
- BADDY aims open source: BADDY will serve, and evolve with the community
- For Everyone: BADDY is made for all the players, anywhere. From players willing to discover that great sport in a really fun and different way, to passionate competitors! BADDY wants to gather a community of amateurs, competitors, players, coaches, clubs, and future players of the Badminton planet.
Learn Badminton with BADDY:
Play with BADDY when I am a competitor:
- Affordable and sustainable: Accessible to players and clubs on a budget. Designed with a "makers" mindset. Don't waste, and invest in costly proprietary technologies. Instead: learn, maintain your robot, by sharing and growing with the community. Ensure your product evolves at the pace of the needs of the community
- BADDY Everywhere: "BADDY everywhere" aims to support emerging countries and very low budgets associations in promoting badminton locally. Through this Kickstarter campaign, BADDY will sponsor the badminton association of Madagascar: BAOBAD. This association runs many solidarity projects, around badminton, with passion and faith.
Having a BADDY will enable to attract new players, boost promotion of badminton locally, and support their indoor and outdoor events. If this Kickstarter campaign is successful, we will give to the BAOBAD association a BADDY DIY kit. Contribute to the project with the dedicated pledge "Sponsor a club" and be a pioneer in this great initiative. You will have the opportunity to be notified of the project progress (get pictures, notifications of when the BADDY will be delivered etc.).
BADDY Launcher aims open source. Plans and source code will be shareable and made accessible to the community, so that everyone can build a BADDY Launcher by its own. BADDY is an open project, a product driven by the community, for the community.
This is how to make your BADDY:
BADDY' HQ is in the greatest Hacker space of Europe called Electrolab. A well known place of 1.500m2 where everything is possible. You will meet here the best engineers, experts, start-ups, skilled entrepreneurs who know what it is to develop new ideas from scratch. www.electrolab.fr
FIND MY HACKER SPACE, NEAR TO ME:
BADDY involves 3 different components: BADDY Launcher, BADDY feeder, GO BADDY app. Each part is now functional, but yet has limitations. This Kickstarter campaign will enable to develop and produce the critical components that could not be developed so far without a significant investment; the mandatory components where the DIY approach is not possible.
- Set up your BADDY in less than a minute - How it works:
- Connect to BADDY with GO BADDY app, and define a simple playing sequence (Drop Left/Right)
- Define a loop playing sequence (Left/Right drop shot)
- Define a random playing sequence (Left/Right drop shots)
- Successive drive shots with Left/Right directions, at 1 second interval - feather birdies
- Plastic and feather shuttlecocks compatible
- Autonomy: 90min
- Size: 25x25x20cm
- Weight: 4Kg
- 9 standard strokes available: Drops, Drives, Clears in 3 directions Left, Center, Right
- Max strokes frequency: 2 per second (consecutive strokes of same type) 1 per second (consecutive strokes of different types)
Technical components highlights:
- Li-ion battery 12V, charger 5A
- Brushless motors /ESC, Servo motors 5Kg
- Open source electronics (Arduino based)
- Bluetooth connectivity, HC0x module
- LED square with MAX7219 controller
- BADDY Woody case: lasercuted wood materials: MDF/internal structure + real wood veneer mouldings.
- BADDY Koala case: lasercuted PMMA
- Wheels durability: Not robust enough (lasts several hours and then tires goes off the rim). We have tried to push the boundaries of DIY using 3D printing, mixing PLA for the rim and Cheetah for the rubber - unsuccessful - when it comes to shooting several projectiles at 5.000 rpm, you need something specific.
- Battery charging timescale 4 hours - need to be reduced -> BMS (Battery Management System) + charger optimisation
- DIY battery made with battery folder + soldering with BMS needs industrialisation and protection. Makers have the possibility to build their own battery pack (we decline all responsibility in that case - batteries are dangerous and you need to know what you are doing when manipulating it)
- Shuttlecocks get a black "tattoo" on the nose (coloured by the friction with the wheel's black rubber)
- Shot length: Miss one meter distance on clear shots. Lack of eccentricity for clear shots Left/Right / needs customised specific wheels
- Manufacturing+Mounting time: 1 BADDY per day - too long
- Customised wheels will have to be designed and produced (injection acrylic for the rim+ thermoplastic rubber). The shore of the rubber will have to be especially studied to ensure: maximum energy transfer, durability and not marking the shuttle nose with rubber colour
- Dedicated Li-ion battery pack, easy to plug, secured and certified
- Full DFM study to optimise mounting process: target, produce and mount 4 BADDY per days
- Dedicated PCB board with circuitry to lodge electronic components, manage the 5V power - ease of production, and... hackable. Think about a board combining Arduino + bluetooth lodged in a same board, that you can hack the way you want.
- Battery level indicator on front LED panel (warning when under critical threshold, gives battery level at BADDY start up) - otherwise, real time battery indicator displayed on GO BADDY app (see next section)
- Redesign BADDY feet. Two feet become one - increased stability - 3 touch points better than 4.
- Android version available yet (local host only, not published)
- Rally configuration: Combination of maximum 5 different stroke types
- 2 modes available: Loop mode (loop the playing sequence in defined order) Random mode (let BADDY select strokes on the fly from the strokes you have chosen)
- Statistics (Bêta) - Count number of strokes Stroke type dispersion: Drop/Drive/Clear Balance dispersion: Left/Center/Right
- Published free app on Apple store (IOs) and GooglePlay (Android)
- BADDY Battery level indicator
- GO BADDY statistics
- Statistics - distance indicator: Approximates the distance you have run based on your stroke sequence history
- Social: Share your playing sequence, statistics, objectives on social medias (Facebook, Twitter targeted - still open for proposals!)
- 3 tubes' structure
- Capacity: 40 shuttlecocks
- Fillable from the side
- Removable structure to gain room and improve portability
- Folding mechanism (using elastics to keep peaces with each other, speed up folding/unfolding)
- New folding mechanism will enable to reduce by 2 the length of the tubes when folded (keeps room for your bag!)
BADDY - What's included
- The GO BADDY app: free (made available on Android and IOs)
- The BADDY Launcher: you can build it yourself, or ask us to do it for you. 3 versions proposed: DIY, Koala, Woody
White color (DIY and Koala) or Wood (Woody version). It's possible to personalise BADDY Woody (put your name on it)
- BADDY feeder: fillable from the side, capacity 40 shuttlecocks
- Additional perks: get your official BADDY t-shirt!

- Production, mounting (for BADDY Koala, and Woody versions), testing shipment efforts
First BADDY Proof of concept: A birdie can be shot and driven left or right with two wheels, each of which rotating at different speeds.
BADDY prototypes history:
BADDY Timeline - until now:
DFM: Design For Manufacturability
We've got already many feedbacks and features proposal and ideas from players and fans. Not sure yet if we will be able to include some in the shipments scheduled for this campaign. BADDY roadmap features and releases feature scope and specifications will be shaped at the pace of the community:
- BADDY stand adapter: plug BADDY on a tripod (compatible with any camera tripod) to make descending stroke types (e.g smashes). BADDY tripod stand under study.
- BADDY BAG: Personalisable bag to transport your BADDY, feeder, rackets and shuttlecocks in a cool manner!
- GO BADDY app add-ons: Tchat functionality Social media page: profile, trainings, tips and tricks etc.
- GO BADDY app for Smartwatch (Apple, Samsung)
- Hit-me functionality: BADDY detects when hit by a shuttle, enabling new gaming and fun possibilities!
And many others coming soon, imagination is the limit! Let's GO BADDY!
Risks and challenges
BADDY is fuelled by lot of passion and positive energy; but let's face it, making things, is hard. Keeping our head cool, and stay with a conservative approach on what can be actually delivered is in our mind. Initially scheduling delivery of DIY kits for end of year, we took a 2 months wiggle time, because we want to be ready to expect the unexpected.
BADDY's HQ is established within the greatest Hacker space in Europe, a great network of advisors, experts, people who know what it is to make things. We choose to take time to run a pre-DFM study to understand what would be the technical challenges of the project: Assembling timeframe being one challenge, durability being the second one (control over MTBF*). As of today, we have a limited experience on how BADDY will behave in the long run. BADDY has strong mechanical constraints, and durability is a challenge. BADDY is yet a product for makers and developers, and bakers have to expect to tinker with it, proceed with small regular maintenance tasks (tuning, replacements of some parts) that will maintain your BADDY up and running during several years. This will be possible with the support of the community. A successful Kickstarter campaign is the sign that the community is welcoming the project, and ready to write down a common beautiful story.
