Abstract:
Methods and systems for wireless control of robotic devices are described herein. As one example of implementing wireless control of a robot, a computing device may provide an alert, such as visual, audio, and/or vibration signals, when the device is capable of engaging in wireless communication with a robot. Prior to engaging the robot, the device may require some gesture of confirmation from the user, such as a passcode, predefined motion, or biometric input, prior to requesting for some amount of control of the robot. After engaging the robot via wireless communication (e.g., near field communication (NFC)), the device may receive control of the robot and enable the user to input control commands. Additionally, in some instances, the device may be configured to receive a subsequent gesture from the user that requests to relinquish control back to a control system of the robot.
Abstract:
Examples are provided that describe a motion based light display for a robotic arm. In one example, a robotic device comprising one or more components configured to be actuated for movement. The robotic device also includes one or more processors are configured to determine a motion per path metric of the one or more components based on a motion plan associated with the robotic device. The one or more processors are configured to determine one or more feedback characteristics based on the motion per path metric. The one or more feedback characteristics include information indicative of an effect of motion associated with the one or more components. The robotic device also includes an indicator coupled to the one or more components and configured to provide feedback about the one or more components based on the feedback characteristics indicative of the effect of motion.
Abstract:
Examples described may relate to methods and systems for gesture based switch for machine control. Some machines may be operated by computing devices that include touchscreens, and a graphical user interface (GUI) is provided for enabling control of the machines. Within examples, a disconnect switch can be incorporated into the GUI. As one example, to initiate operation of a machine, such as a robotic device, a user may be required to contact the touchscreen at a location and then trace out a pattern. To enable continued operation of the machine, the GUI may require the user to maintain contact with the touchscreen at a “goal” position. If contact with the touchscreen is broken (e.g., for more than a threshold amount of time), the machine operation may be halted, and the process to initiate operation can be performed again on the touchscreen to cause the machine to resume operation.
Abstract:
Examples are provided that describe a motion heat map. In one example, a method includes receiving, an input indicative of an environment including a robotic device. The method also includes receiving information associated with the robotic device such as operational characteristics of the robotic device and a range of motion associated with a component of the robotic device. The method also includes determining a motion per path metric associated with the component of the robotic device based on a simulated operation of the robotic device. The method also includes determining a force associated with the motion per path metric. Based on the force, determining a heat map to demonstrate a varying effect of motion of the component.

Abstract:
Examples are provided that describe a cycloid transmission with an adjustable ring. An example cycloid transmission includes a disc and a motor shaft attached to the disc. The motor shaft is capable of rotating the disc around an outer ring of rollers. The outer ring of rollers surrounds the disc. As the disc is rotated, contact is made between the disc and the outer ring of rollers. A cycloid transmission also comprises an adjustable ring that is interposed between the motor shaft and the disc. A circumference of the adjustable ring can be adjusted in order to cause expansion of a radius of the disc. This expansion will result in increased contact of the disc with the outer ring of rollers and thereby lower backlash during rotation of the disc.

Abstract:
In examples, methods and systems for sensing tension in a timing belt are provided. In one example, a transmission device is provided that comprises a timing belt transmission configured to cause rotation of an output hub, and the timing belt transmission includes a timing belt with markings. The transmission device also includes a detector for detecting the markings on the timing belt as the timing belt is placed under a tension due to a load at the output hub, and a distance between the markings on the timing belt changes as the timing belt is placed under the tension. The transmission device also includes one or more processors for determining output torque of the timing belt transmission based on the distance between the markings on the timing belt or based on a time between detected markings.
