A leader movable body includes a degree of freedom setting unit configured to set a degree of freedom relevant to movement of a follower movable body, and a transmitter configured to transmit the set degree of freedom to the follower movable body. The follower movable body is configured to perform group travel with respect to the leader movable body.

Leader movable body, follower movable body, and group travel control system

A traveling apparatus includes: an operation member configured to be displaced to a first range and a second range; an adjusting mechanism configured to adjust a wheel base length between a front wheel and a rear wheel in such a way that the wheel base length is increased when the user displaces the operation member in a direction away from a reference position in the first range; and a controller configured to control, when the user manipulates the operation member in the first range, a driving unit in such a way that the traveling apparatus travels forward based on a forward movement target speed that has been made to become larger as the wheel base length increases, in which the controller controls the driving unit in such a way that the traveling apparatus travels backward when the user manipulates the operation member in the second range.

Traveling apparatus

Provided is a traveling apparatus including an adjusting mechanism configured to adjust a wheel base length between a front wheel and a rear wheel by an action of the user being transmitted, a command accept unit configured to accept a command for traveling forward or backward from the user, and a control unit configured to, while the command accept unit accepts the command for traveling forward, control a driving unit to drive the traveling apparatus to travel forward based on a forward target speed associated with the wheel base length in such a way that the greater the wheel base length, the greater the forward target speed becomes, and while the command accept unit accepts the command for traveling backward, control the driving unit to drive the traveling apparatus to travel backward based on a backward target speed associated with the wheel base length.

Provided is a traveling apparatus including at least, with respect to a traveling direction, a front wheel and a rear wheel and on which a user rides when traveling. The traveling apparatus includes a driving unit configured to drive at least one of the front wheel and the rear wheel, an adjusting mechanism including a rotation part configured to rotate a front wheel supporting member and a rear wheel supporting member in relation to each other, the adjusting mechanism being configured to adjust a wheel base length between the front wheel and the rear wheel by an action of the user being transmitted, thereby changing an angle formed by the front wheel supporting member and the rear wheel supporting member, and a control unit configured to control the driving unit based on a parameter, the parameter changing in conjunction with the wheel base length.

Provided is a traveling apparatus including at least, with respect to a traveling direction, a front wheel and a rear wheel and on which a user rides when travelling. The traveling apparatus includes a front wheel supporting member configured to rotatably support the front wheel, a rear wheel supporting member configured to rotatably support the rear wheel, an adjusting mechanism configured to adjust a wheel base length between the front wheel and the rear wheel by changing a relative position of the front wheel supporting member and the rear wheel supporting member, and a driving unit configured to drive at least one of the front wheel and rear wheel. The wheel base length adjusted by the adjusting mechanism is associated with a speed of the traveling apparatus achieved by driving the driving unit in such a way that the longer the wheel base length, the greater the speed becomes.

Provided is a traveling apparatus including a front wheel steered by an operation by a user and two rear wheels that are rotationally driven independently from each other disposed along a traveling direction and on which the user rides when traveling, the traveling apparatus including: a front wheel supporting member; a rear wheel supporting member; an adjusting mechanism configured to adjust a wheel base length between the front wheel and the rear wheels by changing, by the user, a relative position of the front wheel supporting member and the rear wheel supporting member; and a controller configured to control a rotational speed of each of the rear wheels based on the wheel base length and a steering angle of the front wheel in such a way that a moving track of the front wheel and moving tracks of the rear wheels draw a concentric arc.

In a traveling apparatus, a front wheel supporting member is coupled to a rear wheel supporting member rotatably around a pivot axis and with a support shaft in such a way that a wheel base length will become variable according to a relative posture of the front wheel supporting member and the rear wheel supporting member. Control is performed so that the greater the wheel base length, the greater a speed of the traveling apparatus in a forward direction will become. When the wheel base length is one at which the speed in the forward direction becomes substantially zero, while the front wheel is oriented in a straight traveling direction, an intersection point where the pivot axis crosses a road surface is located at a position offset from a grounding point where the front wheel is grounded on the road surface toward a side of the rear wheel.

Provided is a traveling apparatus including a front wheel supporting member configured to rotatably support a front wheel; a rear wheel supporting member configured to rotatably support a rear wheel; a driving unit configured to drive at least one of the front wheel and rear wheel; an adjusting mechanism configured to adjust a wheel base length between the front wheel and the rear wheel by a user changing relative positions of the front wheel supporting member and the rear wheel supporting member; a control unit configured to control the driving unit based on a target speed associated with the wheel base length; and a failure detection unit configured to detect a failure in the traveling apparatus. When the failure detection unit detects the failure, the control unit stops the control based on the target speed associated with the wheel base length and performs control to extend the wheel base length.
