Real Hot Wheels track runs from the roof and down the sides of a 1970s Chevy G10 van. Boogie Racers' Roller Boogie Machine does not use the track merely as decoration: visitors can send toy cars down the vehicle and into a roughly 30-foot, six-lane drag strip.
The setup includes an electronic starting gate, infrared finish sensors and a digital timing display, while the van interior keeps the 1970s theme with shag carpet and disco balls. Instead of making a real van merely resemble a toy, the project turns the real vehicle into infrastructure for playing with the toys.
It isn't enough to make a van look like Hot Wheels. The Hot Wheels also have to race down the van. The two scales have folded neatly into each other.
A handheld fan is usually supposed to be small and light. KOBAYASHI KAITO ELECTRO took the opposite route with a 'world's most powerful(?) handheld fan' driven by a Makita power-tool battery for Maker Faire Tokyo 2026. The device is assembled from five 3D-printed parts and accepts the chunky tool battery directly. It remains technically handheld, but its power system has clearly wandered into the world of workshop equipment.
The fan stayed handheld, but the power source suddenly became power-tool grade. Portability is now negotiating with ambition.
Robot vacuums work well on flat floors, but stairs stop them completely. Saros Rover tackles that problem with wheel assemblies that extend like legs, letting the machine lift itself one step at a time. It was demonstrated at IFA 2026.
The robot carefully raises its body onto each tread and cleans as it goes, taking about three minutes in the demonstration. Rather than being carried upstairs by another device, the vacuum itself performs the climb.
Instead of giving the vacuum a ride upstairs, they gave the vacuum legs. That's a very demanding version of independence.
Silly Robots Contest is a San Francisco event where the goal is not usefulness or commercial value, but simply making people laugh. Entries are invited to be whimsical, silly, funny or completely unnecessary, with the event scheduled for September 10, 2026.
The call explicitly welcomes “cursed kinematics,” “unnecessary degrees of freedom” and “beautifully overengineered mechanisms,” celebrating robots that move in the opposite direction from conventional performance competitions.
A robot contest judged by “is it funny?” instead of “is it useful?” feels like a very healthy use of engineering.
Larger robot vacuums can struggle to fit beneath furniture and into other tight spaces. Roomba Duo tackles that problem with a large cleaning robot that carries a smaller companion robot and lowers it to the floor using a mechanical arm on top. iRobot presented the two-robot system as a concept at IFA 2026.
The main unit handles regular vacuuming and mopping, while the roughly 8.35 cm-tall companion can enter places the larger robot cannot. Both share the same home map, dividing the job between two machines of different sizes.
Robot vacuums now have something like parent-and-child roles. The appliance is starting to look more like a tiny team.
Library for Ants is a storage device where a tiny robotic mechanism physically carries 12 microSD cards and inserts them into a reader one by one. Instead of switching solid-state storage electronically, it deliberately moves the media itself.
Maker svofski describes it as a robot that wants to grow up to become a tape library. It is essentially an old large-scale storage behavior carefully transplanted onto one of today's smallest memory formats.
Instead of using microSD because it's tiny, the project uses that fact to say “great, a tiny robot can carry it.” Wonderful reversal.
If a toothbrush is going to target the gaps between teeth precisely, it first needs to see exactly where the liquid should go. CameraJet tackles that with a roughly 100,000-pixel macro camera, machine-learning-assisted gap detection and a targeted liquid jet. Dyson introduced the device in September 2026, and a live view of the mouth can be displayed through the MyDyson app.
To keep the camera's view clear, the system also uses specially designed low-foaming toothpaste. Adding imaging, recognition and liquid control to brushing turns even the toothpaste into part of the system design.
At this point, even the toothpaste feels like part of the hardware stack. Oral care is starting to look like systems engineering.
Practicing badminton alone creates a simple problem: someone still needs to feed the shuttlecocks. This machine solves it by putting a compact Denso VS050 industrial robot arm in charge of shuttle delivery.
A pneumatic gripper picks one shuttlecock from a hopper and carefully feeds it between two high-speed spinning discs for launch. Even metal 3D-printed parts are involved, turning the everyday lack of a practice partner into something closer to a factory automation cell.
No practice partner? Bring in an industrial robot. That's an impressively large equipment budget for a very ordinary problem.
Robot mowers often struggle to trim right up against walls and lawn boundaries. The H510 Pro tackles that limitation with a mechanical arm that moves its main cutting disc outward by about 7.4 cm. The system was shown at IFA 2026.
EdgeSense identifies different boundary types, and when needed the mower physically reaches the blade toward the edge. Side guards and people-and-animal detection handle safety while the machine solves the last few centimeters of mowing in an unusually literal way.
Can't quite reach the edge? Extend the blade on an arm. It's such a wonderfully direct answer to a tiny geometric problem.
A project has turned vacuum-tube logic into an 8-bit computer you can actually play with at home. Built from dual-triode tubes manufactured in the former Eastern Bloc, the machine uses a 16-instruction von Neumann architecture and NOR-based logic reminiscent of Apollo-era computing.
It goes well beyond a logic demo: the wall-mounted system connects to old British Rail flip-digit displays and even a control panel for an airship simulator. Old computing technology is not merely preserved; it has been put back to work as a playable machine.
Vacuum tubes were already enough, then railway displays and an airship simulator joined in. Every component seems to come from a different timeline.
A spinning top eventually slows down, so this project answers by putting a brushless motor, ESC, microcontroller, rechargeable battery and eccentric weight inside the top and keeping it going for roughly two hours. It works without an external base or magnets.
When the spin weakens, the internal mass shifts the center of gravity and adds energy back into the motion. Electronics and mechanical control are deployed directly against the very normal fact that tops stop spinning.
You open a spinning top and discover something close to a tiny robot inside. That's a lot of commitment to not stopping.
