The Worker robot speed bonus applies to logistic robots and construction robots. The basic speed of logistic robots is 0.05 tiles/tick (3 tiles per second) and for construction robots 0.06 tiles/tick (3.6 tiles per second).

Speed versus Range
Players should note that the Worker robot speed research does not appreciably increase the distance robots (of either type) can fly before needing to recharge.
Both types of robots have an internal capacitor holding 1.5 MJ at full charge, and consume 3 kW (= 3 kJ / sec) at all times when airborne (hovering or moving), plus 5 kJ per "meter" (= 1 tile) traveled. Currently (game version 0.16), there is no way in the base game (i.e., without mods) that the capacity of this internal energy store can change.
While increasing robot speed means they cover the same distance faster, and therefore the time-based power cost component is less over that distance, a simple calculation shows that the distance-based component far exceeds the time-based one, and this discrepancy only increases with higher robot speed, making range gains from this effect - these being none too great to begin with - increasingly trivial with further robot speed research.
For example, the first level of Worker robot speed adds less than 5% range; level 5 adds only about 1% range (a bit over 10% cumulative); and level 10 (= 5th "infinite" level) adds about 0.3% range for a cumulative increase for the 10 first levels of about 15% (from ~250 to ~290 tiles). Note that these range figures are based on the assumption robots spend all time airborne moving, none hovering.
Speed at Low Power
Worker robot speed research does increase the speed at which robots move when out of power, as this appears to be defined as a percentage of the current normal travel speed. While the low-power speed remains pitiful, with sufficient robot speed research it is nonetheless a noticeable improvement over the snail-like default.
