Various exemplary methods, systems, and devices for control of surgical tools in a robotic surgical system are provided. In general, a robotic surgical system can be configured to control a surgical instrument in one of first and second modes of operation. In the first mode, the robotic surgical system can be configured to receive an input from a master tool indicating movement of the master tool. In response to the input, the robotic surgical system can be configured to cause the instrument to corresponding move. In the second mode, the robotic surgical system can be configured to receive an input from the master tool indicating movement of the master tool, and, in response to the input, adjust a non-positional output characteristic of the instrument. The robotic surgical system can be configured to switch control of the instrument between the first and second modes.
