Use of brackish groundwater could supplement or in some places replace the use of freshwater sources and enhance our Nations water security However a better understanding of the location and charac ter of brackish groundwater is needed to expand dev Makes up 23% of Earth’s freshwater.. 12% Shallow (we can reach). 11% Deep (out of our reach).

Autonomous recharging is becoming increasingly important to mobile robotics as it has the potential to greatly enhance the operational time and capability of robots. Current research in autonomous recharging favors a mobile robot that can recharge a group of worker robots. Existing approaches however have little to no coordination between a recharging agent and its workers. This leads to less efficient interactions which adversely affect the performance of the team of robots, especially as the ratio of worker robots to recharging robots increases. Therefore, improved coordination can greatly enhance the performance of such a team. Furthermore, recharging robots could have capabilities beyond recharging and can thus further contribute to team performance. The current literature does not . sandstone and .
