I watched a Marco Reps video last night when I should have been working and was surprised by his overpowered screwdrivers with goofy animated OLED screens and 1500-watt quadcopter motors and the like. It led me to thinking about what you could use the modern cheapness of control electronics for in hand tools.
One semi-obvious example is impact drivers, which avoid disastrous screwdriver camout by simultaneously exerting force axially “down” onto the screw. Traditionally these are operated manually with a hammer, but there’s no particular reason not to operate them internally with a spring, like an automatic center punch. And if you have electrical power, you could power it internally, like a hammer drill or rotary hammer.
In an impact driver it may be necessary for the axial force to be large: it must be larger than the camout force generated by the inclined planes, and the rotary force normally needs to be large enough to overcome the screw’s stiction, which is possibly larger than normal due to the axial force (so increasing the axial force without bound makes things worse). However, the requirement on the impact energy is minimal: it needs to be enough to overcome stiction. But you could imagine that, at least for some screws, a very large number of impacts with very high peak force but low energy would work adequately. In the limit you’re approaching ultrasonic sonication of the screw as you twist it, making this a real-life “sonic screwdriver”.
