Title:
ELECTRICALLY-DRIVEN HAND CART AND SURGERY SUPPORT ROBOT
Document Type and Number:
Japanese Patent JP2020104843
Kind Code:
A
Abstract:
To improve controllability in positioning a hand cart at a target position in an electrically-driven hand cart which is suitable for a base part of a surgery support robot.SOLUTION: An electrically-driven hand cart includes: a body which has a driving wheel and travels by rotations of the driving wheel; an electric motor for rotating the driving wheel; a controller which controls the electric motor so that a rotational speed of the electric motor is a target rotational speed; an operation input device for inputting the operation amount relative to a travel speed of the body; a handle which has a grip gripped by an operator for manipulating the body; and a gripping intensity detection sensor which is provided on the grip for detecting gripping intensity of the grip by the operator. The controller obtains a gain with a positive correlation relative to the gripping intensity, obtains the operation amount amplified by the gain, and obtains the target rotational speed of the electric motor based on the operation amount.SELECTED DRAWING: Figure 7
