To possess a nextbot, there are two ways:

1. Within the spawn menu's weapons tab, there should be a subsection called "DrGBase." Within it is a possession weapon. When equipped, aim and shoot at the nextbot you want to possess.

2. Hold the context menu button (default is C) and right-click the nextbot you want to control. Then, click on "possess."

Side Note: All of the nextbots have friendly fire disabled against allies. To enable it, use the toolgun's Set Relationship tool to turn the bots against each other.
