The BIGCrawler 2

Introducing the BIGCrawler 2!

BIGCrawler 2 and the BIGCrawler 360! 

Our original BIGCrawler has proven to be the most capable crawlspace UAV available, we have built and improved on that platform with our new BIGCrawler 2.

The improvements start with our all-new chassis. The front and rear axles are now both Hi-Pinion gear, small pumpkin style housings with increased driveline height. This translates into increased ground clearance and has improved its ability to go over obstacles like 4” plumbing drains.

The steering is vastly improved with 8-degree kingpin angles and full 45-degree turning, combining to make this the tightest turning BIGCrawler we have built. The electronics are correctly positioned on the chassis to create the correct low center of gravity and forward weight bias.

We have kept the overall height low (6-1/2” to the top of the roll bar) while significantly increasing the ground clearance, this allows it to go under or over most crawlspace obstructions.

More New and Improved Features!

Our custom 3D designed and printed parts have been made to create the BIGCrawler. From the front camera bumper designed to glide over vapor barriers, to the rear electronics box with vented lid and leash attachment point, all work together to create a sleek and functional package. Wiring is hidden from view and damage, the roll bar at the top protects the camera in case of a rollover. Side panels were designed to keep cables and wires from getting wrapped around the tires.

We have replaced the motor and gearing to slow down the BIGCrawler to allow for easier control which allows for precise driving in tight spots. Three led light bars to illuminate the crawlspace for viewing and proper recording of conditions

.

We introduce our one switch activation system. You can now power the BIGCrawler unit up with the throw of a single switch.

The BIGCrawler 360 is based on the BIGCrawler 2 with some additional features which includes; three additional light bars, one at each side and one at the rear to provide even lighting for the 360 camera. The bodywork changes slightly with 15mm wider side panels to mount the led lights, a mount for the Theta Ricoh 360 camera (not included), a rear light mount and a wiring box with switch for the additional lighting.

A six-channel radio system was chosen for control, the right stick controls the crawler steering and motor, the left stick controls the 180-degree pan and the tilt movements for the camera. A 3-position channel is used to allow you to remotely change from stand-by (not recording), to 1080p video recording, to 16M picture taking, all from the controller.

You can record the crawlspace, when you see a problem you can switch remotely to taking pictures, take a few of the problem, then switch back to video and continue inspecting. All from the controller.

Crawlspace conditions are viewed through a 7” HD DVR screen mounted to the controller. Recording of the video is handled by a micro SD memory card at the camera.

These new BIGCrawlers were built using the ideas and techniques I learned from building the original. The improvements have made for a more user easy friendly experience, with ease of use and enhanced crawlspace maneuverability.

Both units come complete, ready to run with battery charger included. You can take it out of the box and go directly into a crawlspace. Case not included.

The cost of the BIGCrawler 2 is $2299.99 + S&H and tax if applicable.

The BIGCrawler 360 (camera not included) is $2499.99 + S&H and tax if applicable.
