Abstract
A robotic medical device system includes a robotic medical device and a controller. The controller is configured to control, in response to one or more control signals, movement of the robotic medical device to maintain a substantially constant overshoot for different step responses of the robotic medical device system independent of variations in a delay associated with control of the robotic medical device, the one or more control signals received via a network.

A robotic medical device system comprising:
- a controller configured to, in response to one or more control signals, perform non-linear scaling of a velocity of a robotic medical device to maintain a constant overshoot for different step responses of the robotic medical device system independent of variations in a delay associated with control of the robotic medical device, wherein
- the one or more control signals are received via a network, and
- the different step responses include different step response settling times for the robotic medical device system.
A method of operating a robotic medical device system including a robotic medical device and a controller, the method comprising:
- performing, in response to one or more control signals, non-linear scaling of a velocity of the robotic medical device to maintain a constant overshoot for different step responses of the robotic medical device system independent of variations in a delay associated with control of the robotic medical device, wherein
- the one or more control signals are received via a network, and
- the different step responses include different step response settling times for the robotic medical device system.
A robotic medical device system comprising:
- a controller configured to, in response to one or more control signals, perform non-linear scaling of a velocity of a robotic medical device to maintain a constant maximum overtravel distance of the robotic medical device independent of variations in a delay associated with control of the robotic medical device, wherein
- the delay is between a maximum acceptable delay threshold and a disable threshold,
- the maximum acceptable delay threshold is greater than zero,
- the one or more control signals are received via a network,
- the non-linear scaling of the velocity is at least partially based on the constant maximum overtravel distance of the robotic medical device, and
- the controller is configured to constrain the velocity of the robotic medical device to maintain the constant maximum overtravel stance in response to the delay being between the maximum acceptable delay threshold and the disable threshold.
