Each bot and the Farmer/Player may only hold one "tool" in its hands at any one time. It may hold multiple tools in its inventory or backpacks. Of course, everyone needs to correctly select to which bot you wish to give an axe and to which other bot you wish to give a shovel or spade or something else. You can press the space bar on your PC to blow the "whistle" which will show the names of all of the bots so you can select the right one. You can also click on the "bots" icon at the right side to show the list of all of the bots, and then you can click on the name of one of them to select it. Be sure to give your bots names that are meaningful. I like to name my bots by their task such as "Tree Chop", rather than naming them "Bob" or "Sam".
