Send This FPV Bot Into The Crawlspace To Do Your Dirty Work

April 18, 2023 by 27 Comments

The least pleasant space in most houses is likely to be the space below it. Basements tend to be dank, dusty, and full of too many things that have too many legs. And even worse than the full basement is the dreaded crawlspace, which adds claustrophobia to the long list of unpleasantries that lie below. Sadly, though, a crawlspace might be a handy place to run wires, and if you’re hesitant to delve too deeply, this FPV cable-laying rig might be something to keep in mind.

This one comes to us from [Old Alaska] with very little detail other than what’s in the brief video below. The setup is clear enough — a need to run an Ethernet cable from one side of the house to the other, and a crawlspace to do it in. Also in the toolkit was an RC rock crawler with a field-expedient FPV camera. With Breaking Bad-style access to the crawlspace through a few floorboards, [Old Alaska] was able to deploy the crawler dragging a Cat 5 cable behind it. The terrain under the house made the rock crawler a good choice, with four-wheel-drive, locking differentials, and an articulating frame. The bot’s-eye view also makes it clear that actually crawling in this rubble-strewn crawlspace would be a painful affair.

With very little drama, [Old Alaska] was able to navigate the crawler across the crawlspace to the outer wall of the house, where he could fish the wire out and complete the connection — no fuss, no muss, no bloody knees. The only quibble we’d have is not running an extra length of pull rope with the wire. You never know when it’ll come in handy.

The whole thing reminds us of a more tactical version of [Cliff Stoll]’s subterranean inventory management bot.

Digging Out An Underground Workshop

September 6, 2022 by 31 Comments

[Michael] of Teaching Tech moved, and with a large crawlspace under the house, he decided to turn it into a workshop.

There were a few challenges that needed to be addressed first. He had to dig out the crawlspace to provide a level surface, though the depth was limited by the concrete footers the building stands on. The house is sitting on and around large amounts of limestone, which is excellent from a stability standpoint but causes problems for [Michael]. Water can easily travel through limestone, meaning it ends up in his newly dug-out crawlspace. He dug trenches for water to exit and laid down gravel. After a few attempts to level the floor, he found some recycled plastic floor mats and finally got them where he liked them.

Wheeling his tools down a long and steep hill to the shop looks like most of the challenge. But with a few additions to the shop, like hard tube dust extractions and a french cleat system, he has an incredibly functional dedicated shop space.

If your crawlspace is too small for people, a tiny remote-controlled forklift could turn it into the storage space you need.

Tiny Forklift Makes Unusable Space Usable

May 30, 2019 by 25 Comments

Houses with crawlspaces are fairly common in some geographic regions. The crawlspace can make it easier to access things like plumbing and electrical wiring, and can even be used as storage in homes that don’t (or can’t) have a basement. Along with improved building ventilation, these some of the perks compared to homes built on a solid slab of concrete. These crawlspaces aren’t exactly easy to get around in, though, but [Dave] has an easier way to get stuff in and out of these useful, but small, spaces.

Enter the crawl space forklift. Made with largely off-the-shelf components, the robot includes a few standard motors and linear actuators to move around and operate the front fork. That’s all pretty standard, but this build really shines with its use of FPV camera, monitor, and transmitter that allow the pilot to navigate the robot in the small space using remote control. For those safety-conscious among us, there is also a fire extinguisher ball on board which self-activates in case the robot catches on fire under his house.

This is a great, high-quality build that shows how common parts can make something revolutionary with the right idea. Identifying a problem and then building a solution, while not forgetting to spring for some safety equipment, can really make a difference even with something as simple as unoccupied space in a home. They can tackle tasks around the home, too.
