AI summary

Techniques relate to determining a region associated with an object to assist in controlling a robotic arm. For example, a system can determine that the robotic arm is positioned adjacent to an object within an environment. The system can determine a region in the environment that is associated with the object based at least in part on a position of a distal end of the robotic arm. The system can control the robotic arm or another robotic arm to move in the environment based at least in part on the region.
