Abstract: A method is provided that includes controlling a robotic gripping device to cause a plurality of digits of the robotic gripping device to move towards each other in an attempt to grasp an object. The method also includes receiving, from at least one non-contact sensor on the robotic gripping device, first sensor data indicative of a region between the plurality of digits of the robotic gripping device. The method further includes receiving, from the at least one non-contact sensor on the robotic gripping device, second sensor data indicative of the region between the plurality of digits of the robotic gripping device, where the second sensor data is based on a different sensing modality than the first sensor data. The method additionally includes determining, using an object-in-hand classifier that takes as input the first sensor data and the second sensor data, a result of the attempt to grasp the object.

Abstract: A robotic gripping device is provided. The robotic gripping device includes a palm and a plurality of digits coupled to the palm. The robotic gripping device also includes a time-of-flight sensor arranged on the palm such that the time-of-flight sensor is configured to generate time-of-flight distance data in a direction between the plurality of digits. The robotic gripping device additionally includes an infrared camera, including an infrared illumination source, where the infrared camera is arranged on the palm such that the infrared camera is configured to generate grayscale image data in the direction between the plurality of digits.

Abstract: Methods, apparatus, and computer readable media applicable to robots, such as balancing robots. Some implementations are directed to determining multiple measures of a property of a robot for a given time and determining a final measure of the property of the robot for the given time based on the multiple measures. One or more control commands may be generated based on the final measure of the property and provided to one or more actuators of the robot.

Abstract: An example system includes a transmission having a first plurality of gears and an extent of backlash. The system also includes a first motor connected to an input shaft of the transmission and a second motor connected to an output shaft of the transmission through a second plurality of gears. A first gear ratio of a first plurality of gears is greater than a second gear ratio of the second plurality of gears. The system may receive a command to change a direction of rotation of the output shaft from a first direction to a second direction. In response to the received command, the first motor may drive the transmission through a first portion of the extent of backlash deadband. The second motor may drive the transmission through a second portion of the extent of backlash deadband. The second portion may be greater than the first portion.

Abstract: A combination cartridge apparatus includes a housing, an inkjet pen and a media cartridge. The combination cartridge is configured to hold the inkjet pen and media cassette adjacent to each other external of a printer. The inkjet pen and media cassette are configured to separate when the cartridge is installed in a printer and to rejoin when the cartridge is withdrawn from the printer.

Abstract: A cartridge apparatus includes a media cassette, face plate and a locking and unlocking mechanism. The locking and unlocking mechanism includes a lock bar, a first post and a second post, and is configured to lock and unlock a cartridge during insertion in a printer.

Abstract: A printer system including a tray adapted for use with a printing mechanism. The tray includes a stationary portion, a rotatable portion, and a length adjuster. The stationary portion is adapted to be coupled with the print mechanism. The rotatable portion is rotatably coupled with and extends a first length from the stationary portion. The length adjuster is slidably coupled with the rotatable portion and is adapted to move along an adjustable length. The adjustable length is greater than the first length of the rotatable portion.

Abstract: A print cartridge support system for locating a print cartridge in a printer includes a cartridge docking bay and a latch mechanism. The cartridge docking bay is configured to removably receive the print cartridge. The latch mechanism includes a body and a retainer. The body is movably supported relative to the bay for movement between a closed position and an open position. The retainer is movably coupled to the body to move between a retaining position in which the retainer releasably engages the bay when the body is in the closed position and a releasing position.
