FAQs

What is the maximum cable length?

The standard cable length on the reel is 250 feet. There is also the possibility to provide a shorter or longer cable length if a request is made.

What is the crawlers radiation limit?

The crawler has been exposed to radiation limits of up to 100 Rad. to date. It's complete upper limit has not been determined. The most common application uses a camera sensor mounted onto the vehicle. The camera sensor does not have any specific radiation cladding or protective barrier and ultimately would be the limiting factor.

What size objects can it crawl over?

The bottom chassis plate of the crawler has a 1” clearance so it can traverse any objects 1 inch or less in height.

Can it climb stairs?

Currently it cannot climb stairs however there are other designs available if this is a particular option you would need.

What is the maximum speed?

The current crawler design has a minimum top speed of 1 feet per second.

Can the crawler move with the mast completely erected, if so how fast/slow?

No, the speed is very limited up to 4 feet due to the higher center of gravity.  The crawler cannot move after the mast is raised past 4 feet.   

What is the Ingress Protection (IP) rating for the crawler – chassis and camera?

The Ingress Protection rating (IP) for the chassis is an IP50 which indicates there is a limited ingress of dust and no protection against liquids.  And the camera has an IP60 rating this rating suggests there is full protection against dust and no protection against liquids. 

What is the maximum height that the camera can reach?

The maximum height the camera/entire system can reach is 8 feet.   

What power source does the crawler use?

The crawler system uses the United States standard residential voltage of 120 Volts AC. 

Is the track tension adjustable?

Yes, both track tension can be adjusted independently of each other. There is a tension system located inside the chassis on both vertical side plates.

Is the chassis magnetic?

The crawler system itself is not magnetic however there may be some minute magnetic properties with the fasteners. 

Is the crawler very heavy?

The crawler system has a combined weight less than 40 lbs.

Does the crawler use any other input devices besides the controller?

Yes, the crawler system also uses a dynamic keyboard to input titles for the captured video/images.
