StrollerController Free Parents From Menial Labor

Raising young children is hard work, and parents need all the help they can get. There’s a whole industry catering to parents who are willing to pay to make their lives a little easier. Then, we have hacker minded parents like [Sam Pearce] who build his own solutions like joystick-controlled motorized strollers. His kids have fun taking their first steps into independent autonomy, dad has freed up his hands from pushing strollers, and everyone wins!

We were impressed when we saw [Sam] and his StrollerController zipping along at Maker Faire Bay Area 2019. Normally the only way young children get to control their own vehicle is in a field of bumper cars or a constrained track like Autopia. These lucky kids can drive around without being constrained by pen or track. This will give them a great early start on their driver’s license test, assuming autonomous vehicles haven’t taken over by the time they grow up.

The StrollerController we saw is a two part affair, each capable of independent operation:

StrollerController v1 is a stroller enhanced with motor gearbox from cordless drills driving rear wheels. Its top speed can be constrained by a limiter depending on the child pilot’s driving proficiency. It also has a bright red emergency stop button on top, plus a remote controlled kill switch held by a supervising adult.

StrollerController v2 is a pusher module equipped with much faster wheelchair motors under an grownup-sized standing platform. Welded to the front is a pair of brackets to dock with either a regular non-motorized stroller or StrollerController v1. The linked system delivers expedient travel for both parent and child.

For such a display of inventive ingenuity and resourcefulness, this project won a well-deserved Editor’s Choice ribbon from Maker Faire. We hope such recognition and enthusiasm from other Maker Faire attendees helped motivate [Sam] as he continues to improve StrollerController.

Hackaday Prize Entry: Powered Running Stroller Keeps You Running

Types of strollers called ‘running strollers’ exist to make it possible to bring your toddlers along for your run but try it with two four-year old, 38 lb young ones, against the wind, and up enough hills and you’ll quickly lose steam. [Andrew Clink]’s and his wife’s solution? Modify the stroller to be a self-powered roadrunner.

[Andrew]’s hackaday.io build logs are detailed, including design, calculations, schematics, 3D printing files, fails and retries, and more. Power is provided by a bank of lithium-ion batteries that drive a brushless motor. The motor turns the stroller’s front wheel using a toothed belt around a small motor pulley and a larger 3D printed wheel pulley, providing a 13.92:1 gear ratio. [Andrew] considered a number of methods for steering, and even tried a few, but given that his paths are mostly straight lines, small adjustments by hand are all that’s needed. For the possibility of the stroller getting away from him for whatever reason, [Andrew] wrote an iOS app for his phone that makes use of the Bluetooth LE Proximity profile (PDF). It communicates with a small remote using an nRF8001 Bluetooth connectivity IC and for added safety has a belt clip and a stop button.

Does it work? See for yourself in the video below. We’re sure [Andrew] and his wife will continue to be fit for a long time to come.

Baby’s First Hands-Free Stroller

So you’ve had your first child. Congratulations; your life will never be the same again. [Dusan] was noticing how the introduction of his children into his life altered it by giving him less time for his hobbies in his home laboratory, and decided to incorporate his children into his hacks. The first one to roll out of his lab is a remote-controlled baby stroller.

After some engineering-style measurements (lots of rounding and estimating), [Dusan] found two motors to drive each of the back wheels on a custom stroller frame. He created a set of wooden gears to transfer power from the specialized motors to the wheels. After some batteries and an Arduino were installed, the stroller was ready to get on the road. At this point, though, [Dusan] had a problem. He had failed to consider the fact that children grow, and the added weight of the child was now too much for his stroller. After some adjustments were made (using a lighter stroller frame), the stroller was eventually able to push his kid around without any problems.

This is an interesting hack that we’re not sure has much utility other than the enjoyment that came from creating it. Although [Dusan]’s kid certainly seems to enjoy cruising around in it within a close distance to its operator. Be sure to check out the video of it in operation below, and don’t forget that babies are a great way to persuade your significant other that you need more tools in your work bench, like a CNC machine for example.

Land Speed Baby Carriage Record Set At 53 Mpg

53-mpg-baby-carriage

Let’s face it, you’ll never break the motorcycle land speed record without a stellar engineering team and some serious corporate sponsorship. But this build proves that individuals can still set other speed records. [Colin Furze] rode his motorized baby carriage over the 53 mile per hour mark to set a the world’s record. We were surprised to learn it only took him about one month and $750 to build the infant death machine.

The design appears to take a page from the commercial lawnmower industry. We say that because the driver rides along on a little tow dolly behind the carriage itself. All of the controls are mounted within easy reach of the T-bar steering mechanism. There are a couple of rockers for his thumbs which actuate the gas and brakes. Red push buttons just below the handlebars are used for up and down shifting with a third button used as a kill switch. The only thing missing from the write up is video footage of the actual 53mph run. We guess you’ll just have to take his word for it.

Robot Stroller Lets Baby Steer Without Mowing Down Other Toddlers

We’ve seen strollers and car seats that have a steering wheel for the baby to play with (like in the opening of The Simpsons). But what we hadn’t seen is a stroller that allows baby to actually steer. You might think that a putting a motorized vehicle in the hands of someone so young is an accident waiting to happen. But [Xandon Frogget] thought of that and used familiar hardware to add some safety features.

The stroller seen above is a tricycle setup, making it quite easy to add motors to the two rear wheels. These are controlled by a tablet which you can see nestled on the canopy of the stroller (look for the light reflected on the glass). This interfaces with two Kinect sensors, one pointing forward and the other pointing back. They continually scan the environment, looking for obstacles in the stroller’s path. You can see [Xandon’s] little girl holding a Wii Wheel, which connects with the tablet to facilitate steering. A test run at the playground is embedded after the break.
