A robot includes a driving unit, a flexible board including a power line that transmits electric power to the driving unit, and a choke coil connected to the power line. A band rejection filter is formed by parasitic capacitance, which is formed by the electric line, and the choke coil.

Robot with a flexible board having reduced noise leakage

A robot includes a robot arm, a drive unit that drives the robot arm, a first control unit that controls drive of the drive unit, a plurality of detection units at least one of which is an angular velocity sensor as an inertial sensor, and a wiring unit that series-connects the plurality of detection units and the first control unit.

Robot, controller, and robot system

A robotic device having an arm including an actuator and inertial sensor, a first calculator adapted to calculate an angular velocity and an angular acceleration of the actuator based on a rotational angle data from an angle sensor, a second calculator adapted to calculate one of an angular velocity and an angular acceleration of the arm based on an output detected by the inertial sensor, and a comparator adapted to compare one of the angular velocity and the angular acceleration calculated by the first calculator and one of the angular velocity and the angular acceleration calculated by the second calculator with each other, and it is determined that the inertial sensor is at fault if an absolute value of the difference between the actuator and the arm in one of the angular velocity and the angular acceleration in the comparison section is larger than a threshold value.

Robotic device and method of controlling robotic device

A robot includes: an arm driven by a motor; an angle sensor that detects a pivoting angle of the motor; an inertia sensor that detects an inertial force acting on the arm; a noise detecting unit that detects a noise frequency of the inertia sensor from both an output of the angle sensor and an output of the inertia sensor; a filter-constant determining unit that determines a characteristic of a filter from information of the noise detecting unit; and the filter that removes noise of the inertia sensor on the basis of the filter-constant determining unit.
