A self-aligning tool guide has a holder for securing a portable power tool for working on a ceiling, a lifting mechanism, and a self-balancing chassis. The holder is mounted on the lifting mechanism. The lifting mechanism has a propulsion system for raising the holder parallel to a lifting axis. The self-balancing chassis has two wheels on a wheel axis and a drive coupled to the two wheels. A sensor serves for detecting a contact pressure of the holder, the contact pressure acting in the direction of gravitational force. The control station activates the propulsion system depending on the detected contact pressure.

Motorized hub assemblies for use with platforms and the corresponding motorized platforms are presented. At least one of the hub assemblies can be a motor and can contain an internal motor to propel the platform when activated. In some embodiments, the motorized platform has two sets of motorized wheels or two sets or motorized treads for differential rate maneuvering. In some embodiments, different base platforms are mounted to a single set of wheels or a single tread to provide a sporty style ride. A handlebar can also be implemented for greater stability. In all cases, there is no requirement for an electronic stabilization platform.

A self-propelled device is disclosed that includes a center of mass drive system. The self-propelled device includes a substantially cylindrical body and wheels, with each wheel having a diameter substantially equivalent to the body. The self-propelled device may further include an internal drive system with a center of mass below a rotational axis of the wheels. Operation and maneuvering of the self-propelled device may be performed via active displacement of the center of mass.

An electro-mechanical gyro-balanced unicycle includes a wheel provided with a first motor, a housing provided outside the wheel and hollow pedals respectively provided at both sides of the housing. The pedal is provided with an electro-mechanical gyro assembly, and the electro-mechanical gyro assembly includes a second motor and a rotor capable of being driven by the second motor to rotate at a high speed so as to produce torques in a horizontal plane. The unicycle has a simple structure, can enable a beginner to be capable of quickly getting on the unicycle without any external assistant force, and can still well realize self-balance in left and right directions over time.

Provided is a self-driving vehicle, e.g., a follower vehicle, that engages in communicative behaviors using body dynamics. Also provided is a method of using body dynamics to communicate behaviors in a self-driving vehicle. The vehicle may include a shifting assembly configured to shift and/or tilt a vehicle body to communicate such behaviors, e.g., acceleration, deceleration, and near constant velocity. The shifting and/or tilting of the body in combination with the vehicle's operation communicates those operations to bystanders. With better informed bystanders, improved safety between bystanders and the vehicle may be achieved.

The disclosure relates to an anti-theft method for a balance vehicle, a device, and a non-transitory computer readable medium. The method includes measuring a first set of physiological characteristics of a first user that is currently occupying the balance vehicle; retrieving a second set of physiological characteristics from storage, wherein the second set of physiological characteristics is associated with at least one second user that is permitted to operate the balance vehicle; comparing the first set of physiological characteristics with the second set of physiological characteristics; determining whether the first user is different from the second user based on the comparison; and generating a prompt that is configured to indicate whether the first user is different from the second user based on the determination.

An electric vehicle is provided with a highly simple and convenient structure for detachably retaining a battery, and enabling the vehicle to be lifted by hand. A battery case of the electric vehicle includes an upper extension (80F, 80G) including an upper member (80G) configured to be gripped by a hand for lifting the vehicle, and defining a gripping space (112) for receiving the hand between an upper surface of the battery received in the battery case and the upper member, and a latching structure (102, 106, 120) is provided between an upper part of the battery and an opposing part of the battery case, the latching structure including an operating member (104) positioned inside the gripping space.

The disclosure supports accident prevention or evacuation action of a user who is on board a moving body when a disaster occurs. A moving body control device includes: a moving body control part that controls a moving body maintained in a first state or a second state that is more stable than the first state by a balance control mechanism; and an event detection part that detects an occurrence of a predetermined event. The moving body control part stops the moving body from traveling and causes the moving body to change to the second state regardless of a driving operation of the moving body by an occupant of the moving body in a case where the event detection part detects the occurrence of the predetermined event.

The disclosure allows an occupant to control a vehicle as needed for the vehicle that automatically moves to a destination. An inverted pendulum type vehicle that travels while balancing an inverted pendulum type body includes: an operation input part that receives a driving operation of its own vehicle by a weight shift of an occupant; and a movement control part that causes the own vehicle to start automatic movement on a predetermined route at a predetermined time. The movement control part allows the own vehicle to deviate from the predetermined route and travel in a second direction when a weight shift greater than a threshold value is performed in the second direction other than a traveling direction related to the predetermined route during execution of the automatic movement.
