Atlas Devices have created a rope-climbing mechanism that can carry up to 250 pounds but also lift said weight at a rate of 10 feet per second. It runs on battery power and is under contract to be made for the Army and also rescue workers.

It looks extremely useful for these occupations and probably a lot of fun for those using them. It’ll make anyone use it feel like Batman for a brief moment until reality starts to settle back in.

Watch it in action here.
