Features
RS204MD is specially designed for robotic applications, having the following features.
●
Small and Lightweight
RS204MD is small and lightweight servos specially designed for robots, which are 12g respectively.
●
Interactive High-Speed TTL Communication
TTL bi-directional communication of a maximum baud rate of 230kbps is possible and is
used for the communication between the robot’s processor and servos.
●
Servos for Both Command Type and PWM Type
RS204MD can be controlled either as the Command Type Servo for robots or the PWM Type Servo for
existing R/C servos. The type is automatically switched by the first signal sent after these products are
connected.
●
Feedback(Only as Command Type)
Information of sensors on the servo such as the position, load, temperature, electric current, and the
alarm situation, etc. can be obtained via TTL communication.
●
Compliance Control
With this feature, the movement of the RS204MD is controlled in accordance with the distance between
the present and target positions. This enables the robot to move very smoothly without trembling its
arms and legs and to absorb turbulence from an external force.
●
Calibration
Angular position of every servo is calibrated by our standard gauge before their shipment. Even if
another RS204MD servo is employed, it does not require any bothersome work for adjusting its angular
position.
●
Wiring from the Output Shaft
In order to avoid wires becoming entangled during operation, they are drawn out from the rear of the
output shaft. Another shaft is installed on the bottom case to make the center impeller structure easy to
construct.
●
Horn with a mark for the reference position
凹
marks are placed on the circumference of the servo horn in order to make sure the reference position
even after being built in. (one
凹
for 0
°
position, two
凹
s for 90
°
position, three
凹
s for 180 position
and four
凹
s for 270
°
position)
