Methods and systems are disclosed for controlling device movement based on a movement command. Issues on accurately controlling movement of a device such as a programmable robot and rover are addressed by first determining a command type of the movement command, followed by determining specific types of controllers for a high-level controller and a low-level controller based on the determined command type. When the command type is a linear movement, a Proportional-Integral-Derivative (PID) controller is used at the high-level controller and a Proportional/Proportional-Integral (PPI) controller is used at the low-level controller to accurately control a target distance. When the command type is an angular movement, the PPI controller is used at the high-level controller and the PID controller is used at the low-level controller to accurate control the end-heading of the device.

Method and system for controlling movement of a device

A wearable device can be worn by a user, and can include one or more sensors to detect user gestures performed by the user. The wearable device can further include a wireless communication module to establish a communication link with a self-propelled device, and a controller that can generate control commands based on the user gestures. The control commands may be executable to accelerate and maneuver the self-propelled device. The controller may then transmit the control commands to the self-propelled device over the communication link for execution by the self-propelled device.

Modular sensing device for controlling a self-propelled device

A modular sensing device can include an inertial measurement unit to generate sensor data corresponding to user gestures performed by a user, a mode selector enabling the user to select a mode of the modular sensing device out of a plurality of modes, and one or more output devices to generate output based on the user gestures and the selected mode. The modular sensing device can further include a controller to implement a plurality of state machines. Each state machine can be associated with a corresponding user gesture by a sensor data signature. The state machine can execute a state transition when the sensor data matches the sensor data signature. The executed state transition can cause the controller to generate a corresponding output via the one or more output devices specific to the selected mode and based on the corresponding user gesture.

Modular sensing device implementing state machine gesture interpretation

A self-propelled device can determine an initial reference frame of the self-propelled device in three-dimensional space, receive control inputs from a controller device, where the control inputs can be inputted by a user on a steering mechanism of the controller device. The self-propelled device can interpret the control inputs as control commands to maneuver the self-propelled device, and implement the control commands on an internal drive system of the self-propelled device to maneuver the self-propelled device based on the control inputs. While maneuvering, the self-propelled device can determine an orientation of the internal drive system within a spherical housing of the self-propelled device in relation to the initial reference frame, and transmit feedback to the controller device based on the orientation of the internal drive system in order to calibrate an orientation of the steering mechanism with the orientation of the internal drive system.

Self-propelled device implementing three-dimensional control

A self-propelled device can include a spherical housing, an internal drive system, and an inertial measurement unit. The self-propelled device can determine an initial frame of reference for the self-propelled device in a three-dimensional coordinate system. The self-propelled device can further receive control inputs from a controller device, translate the control inputs into commands to maneuver the self-propelled device, and implement the commands on the internal drive system to cause the spherical housing to rotate about each axis of the three-dimensional coordinate system. Utilizing the IMU, the self-propelled device can maintain an awareness of an orientation of the spherical housing relative to the initial frame of reference as the spherical housing rotates about each axis of the three-dimensional coordinate system.

A self-controlled device maintains a frame of reference about an x-, y- and z-axis. The self-controlled device processes an input to control the self-propelled device, the input being based on the x- and y-axis. The self-propelled device is controlled in its movement, including about each of the x-, y- and z-axis, based on the input.
