More Information
Summary:Embodiments include devices and methods for maintaining control of a robotic vehicle when control signals from a main controller are lost. A detector circuit may monitor signals from the main controller to an electronic speed controller (ESC) to detect a loss of valid control signals. The detector circuit may cause an auxiliary controller to begin issuing motor control signals to the ESC in response to detecting a loss of valid control signals. The auxiliary controller may issue motor control signals to the ESC according to a pre-loaded set of motor control instructions. The pre-loaded set of motor control instructions may be received from the main controller and/or may be configured to cause the auxiliary controller to issue motor control signals to the ESC that control motors in a manner that causes the robotic vehicle to enter a safe mode of operation or execute a particular maneuver.
