Abstract
A robot includes a motor drive power source for converting a voltage supplied from a power source to a motor drive unit-grade voltage and outputting it, a motor drive unit for converting a motor drive unit-grade voltage output from the motor drive power source to a motor drive voltage and outputting it, a motor driven to be rotated by a motor drive voltage output by the motor drive unit, a robot arm on which the motor drive unit and the motor are arranged, and a robot controller which is provided independently of the robot arm and on which the motor drive power source is arranged.
Claims6
A robot comprising:
- a motor drive power source for converting a voltage supplied from a power source to a motor drive unit-grade voltage, the motor drive power source outputting the motor drive unit-grade voltage;
- a robot arm having a plurality of robot arm segments, each robot arm segment including:
- a motor drive unit for converting the motor drive unit-grade voltage output from the motor drive power source to a motor drive voltage,
- a motor drive unit control unit for controlling the motor drive unit to output the motor drive voltage,
- a motor driven to be rotated by the motor drive voltage output by the motor drive unit, and
- a connection unit creating a direct and continuous connection between the unit-grade voltage output from the motor drive power source to the motor drive unit and another connection unit of another robot arm segment of the robot arm, the direct and continuous connection electrically connecting each of the robot arm segments in parallel with the unit-grade voltage output from the motor drive power source.
