A wheelbarrow braking assembly for slowing or stopping a wheelbarrow includes a brake rotor that is attachable to a wheel of a wheelbarrow. A caliper is mountable to the wheelbarrow such that the caliper is aligned with the brake rotor for slowing or stopping the wheelbarrow. A brake handle is provided that is mountable adjacent to an end of a respective rail of the wheelbarrow. In this way the brake handle is accessible to the user when the user is maneuvering the wheelbarrow. The brake handle is in mechanical communication with the caliper and the caliper is engaged when the brake handle is squeezed. |

Articulated rail coupler
An articulated rail coupler comprises a base member, a female connecting member, a male connecting member, a bearing race, a first bearing seated within the bearing race and defining a vertical axis of rotation, and a second or a coupler bearing configured and sized to be received within a truck bogie bearing bowl. The male connecting member is allowed to rotate relative to the female connecting member about the vertical axis of rotation in a range of about ninety degrees, when the male connecting member and the female connecting member are coupled therebetween by the first bearing. |

Transitioning steering control from an autonomous vehicle to a driver
Techniques are described for transitioning control of a steering system from an autonomous mode in a vehicle to a driver-controlled mode where the driver can control the steering wheel of the steering system. A method includes receiving values that describe an amount of torque and a direction of torque in response to a torque applied to a steering wheel of a steering system operated in an autonomous mode, determining that the values are either greater than or equal to a threshold value or are less than or equal to a negative of the threshold value, determining that the values are measured over a period of time greater than or equal to a pre-determined amount of time, and transitioning the steering system from being operated in the autonomous mode to being operated in a driver-controlled mode in which the steering system is under manual control. |

Autonomous vehicle low battery management
Systems and methods are provided for identifying an imminent low state of charge of a battery in an autonomous vehicle, and automatically powering down the vehicle before a zero state of charge event occurs. In particular, the autonomous vehicle automatically powers down while there is enough energy in the batteries to restart the vehicle and drive the vehicle a short distance to a charging station. |
