    摘要: Aspects of the present disclosure relate to self-heating electric motor control. In examples, a motor controller includes a normal control scheme and a heating control scheme, whereby the heating control scheme causes the electric motor to produce heat (in addition to or in the absence of mechanical operation of the electric motor). For example, if the electric motor has cooled below a minimum operating temperature, the heating control scheme is used to heat the electric motor prior to mechanical operation of the electric motor. As another example, the electric motor may approach or fall below a minimum operating temperature during operation, such that the heating control scheme is used to cause the electric motor to produce additional heat while in operation. Thus, the electric motor is heated as a result of the heating control scheme, as are one or more associated mechanical or electrical components.

    摘要: Aspects of the present disclosure relate to a sample collection assembly for a vehicle. The sample collection assembly includes a perforated ground-engaging member of the vehicle and an associated sample collector. For example, a perforated wheel may collect material from terrain under the vehicle as the wheel rotates (e.g., as may result from movement of the vehicle), which may fall through the perforation and into a sample collector disposed thereunder. In some examples, a ground-engaging member may include one or more grousers, paddles, or scoops, among other terrain interaction features, to further increase the amount of material that is collected. Such terrain interaction features may be unidirectional or bidirectional, thereby offering improved sample collection in one or both directions of operation, respectively. In examples, an image capture device or one or more other sensors may be used to monitor sample collection and/or to process data associated therewith.

    摘要: Aspects of the present disclosure relate to an extendable conductor assembly. A conductor of the extendable conductor assembly may be extended (e.g., into a thermal target, such as a preexisting or a newly created feature of a planetary body) and used to thermally couple a rover, vehicle, fixed installation, or other hardware with the thermal target. Thus, the temperature of the hardware may be managed via heat transfer to/from the thermal target. For instance, heat may be transferred from the thermal target to maintain the temperature of the hardware under cold conditions, while excess heat may be transferred to the thermal target under hot conditions. As an example, a rover may form a borehole in the lunar surface, in which a conductor may be extended to facilitate heat transfer between the rover and the Moon accordingly.

    摘要: A vehicle locking assembly is disclosed, which couples a vehicle to a support member, for example using a frangible bolt and an actuator. When actuated, the actuator causes the frangible bolt to fail, thereby decoupling the vehicle from the support member. Ground-engaging members of the vehicle include terrain interaction features along an outer portion, thereby forming a portion of the ground-engaging member where the terrain interaction features (or, as another example, lack thereof) form a contact region that is radially closer to the center of the ground-engaging member as compared to the contact region(s) corresponding to other terrain interaction features. Accordingly, once the fastener is released, the ground-engaging members of the vehicle are actuated, such that the terrain interaction features engage with the plate/surface beneath the vehicle as the radially closer contact region rotates out from under the vehicle, thereby raising the vehicle off the support member.

    摘要: Aspects of the present disclosure relate to a modular environmental monitoring device. The monitoring device may include a core subassembly that provides core device functionality (e.g., data processing and communication management). A variety of modular subassemblies may be used in combination with the core subassembly, such that functionality of the monitoring device may be changed according to an environment in which the device will be used. For example, different subassemblies may offer different communication modes, such that the monitoring device may be reconfigured to use different wired and/or wireless networking technologies as are available within a given environment. Similarly, a subassembly may include a battery and/or may obtain power from any of a variety of other power sources. Additionally, the monitoring device may automatically determine which communication mode to use depending which communication modes are available, thereby offering improved reliability and reusability.

    摘要: Aspects of the present disclosure relate to environment-based thermal management. In examples, an environment is evaluated using a network of temperature sensors. Additionally, or alternatively, the environment is evaluated using an infrared and/or visible light camera. Candidate features of the environment having associated thermal conditions (e.g., surface temperature, geometry of an environmental feature, and/or degree of exposure to deep space) are detected and used to position a rover, robot, or other hardware within the environment, thereby causing the temperature of the hardware to be mediated by its exposure to features of the environment. Additionally, the rover may reposition itself within the environment in response to changing thermal conditions within the environment and/or changing thermal demands of the rover.
