The biggest gain is that the operator can eliminate a lot of hop on/off activities just to move the truck. Studies have shown that roughly 70 % of on/off activities can be eliminated. This will also result in less strain on the body, particularly legs and feet. It will also speed up the picking process because the operator will spend more time picking and less time driving. Studies have shown that time saving amounts to around 5-15 % in favour of the remote system vs traditional picking.   The higher the picking density is in the aisle, the greater the time saving will be with a semi-automated order picker. Particularly Fast-Moving Consumer Goods businesses can gain from implementing semi-automated order pickers.
