You need a strong rigid cage to protect the operator, with comfortable seating and controls, a large and heavy power source, and something more practical than legs for movement. Put all that together, and you essentially have an excavator. Excavators can do amazing things in the hands of a skilled operator. They have interchangeable tools and they come in a wide range of sizes. Maybe the small ones feel more like exoskeletons than the big ones. Some even have the operator in a standing position. The smallest Bobcat (technically a "loader" instead of an "excavator") is little more than a cage on wheels with one big arm: https://www.bobcat.com/na/en/equipment/loaders/skid-steer-loaders/s70 https://www.bobcat.com/na/en/equipment/loaders/skid-steer-lo... I guess what you're really missing to make this feel like a scifi exoskeleton is two arms, more degrees of freedom per arm, a much more capable "hand", way more speed in all of the actuators, and a more 1:1 control style with some kind of touch sensitivity/force feedback. All of that would make these things way more expensive, complex, and most importantly, fragile. Durability and ease of maintenance is a huge consideration for practical work. Last month I watched a guy in one of these accidentally smash his jackhammer attachment on a low overhang and sever the hydraulic hoses, spraying hydraulic fluid everywhere. I can only imagine that this kind of thing happens all the time. If that was a 20 DOF robot hand with touch sensors instead of a 1 DOF dumb jackhammer attachment, it could easily have been damaged beyond repair.
