Kinda cool but needs arm assist, most menial tasks fail due to tiring upper body strength.

For example, unloading trucks, carrying plaster boards etc. I would kill to have one of these (for arms) the last time I unloaded 50 acoustic plasterboards @ 60kg each in the last office reno.

The truck driver gave me a hand and yeah he was a bit tired but me, I was dead. My bones hurt.
