Abstract
A robot includes a first control device; and one or more second control devices to be controlled by the first control device. The second control device controls a control target controlled by the second control device at a predetermined cycle. The predetermined cycle is determined based on first information received by the second control device from the first control device at a first time point and second information received by the second control device from the first control device at a second time point.
Claims14
A robot comprising:
- a first control device configured to send first, second, and third information;
- and
- one or more second control devices to be controlled by the first control device, each of the second control devices controlling a control target at a predetermined cycle, each of the second control devices having a memory and a processor, the memory being configured to store a program, the processor being configured to execute the program so as to:
- receive the first information from the first control device;
- save a first time at which the first information is received in the memory;
- receive the second information from the first control device;
- save a second time at which the second information is received in the memory;
- receive the third information from the first control device:
- save a third time at which the third information is received in the memory;
- calculate a first period of time between the first time and the second time;
- calculate a second period of time between the second time and the third time;
- calculate a mean period of time based on the first period of time and the second period of time;
- and
- designate the mean period of time as the predetermined cycle.

A robot system comprising:
- a robot having:
- a base;
- an arm connected to the base;
- and
- a motor disposed in the arm and the motor being configured to rotate the arm relative to the base;
- and
- a first control device configured to send first, second, and third information, and
- one or more second control devices to be controlled by the first control device, each of the second control devices controlling a control target at a predetermined cycle, each of the second control devices having a memory and a processor, the memory being configured to store a program, the processor being configured to execute the program so as to:
- receive the first information from the first control device;
- save a first time at which the first information is received in the memory,
- receive the second information from the first control device;
- save a second time at which the second information is received in the memory;
- receive the third information from the first control device;
- save a third time at which the third information is received in the memory;
- calculate a first period of time between the first time and the second time;
- calculate a second period of time between the second time and the third time;
- calculate a mean period of time based on the first period of time and the second period of time;
- and
- designate the mean period of time as the predetermined cycle.
