High Accuracy Large Torque Small Size Robotic Servo Motor

Feature:

The servo actuator from Robotis is the advanced

on the market in low price range and has become the defacto standard

for the next generation of hobby robotics. The robot servo has

the ability to track its speed, temperature, shaft position, voltage,

and load.

As if this weren't enough, the control algorithm used to maintain shaft position on

the SCS215 actuator can be adjusted individually for each servo,

allowing you to control the speed and strength of the motor's response.

All of the sensor management and position control is handled

by the servo's built-in microcontroller.

This distributed approach leaves your main controller free to perform other functions.

Specification:

Picture:

1.SCServo can work at servo mode and wheel mode.

The servo mode can be used to multi-joints robot since the robots can be controlled with specific angles. ( The factory default setting is servo mode)

The wheel mode can be used to wheel-type operation robots since motors of the robots spin infinitely. (If wheel mode is available you need to program the value of position limitation the both are 0.)

If you want to reprogram servo, you need to download the PC software (SCServo_Debug), and to connect SCPC-2(Serial Control Programming Card) between servo and PC.

More about SCServo_Debug and SCPC-2 introduce please reference its instructions.

2.SCServo has a unique ID number to identify on BUS network.

The range from 0 to 253 (0xFD) can be used ( The factory default setting is ID 1), and, especially, 254(0xFE) is used as the Broadcast ID. If the Broadcast ID is used to transmit Instruction Packet, we can command to all SCServo.

After programmed servo ID, to be best way is written it on the sticker of servo. If not, maybe you will forget the ID when you programmed many servos.

3.SCServo have kinds of baud rate available.

The baud rate from 38400 bps to 1M bps can be used.

They are 38400, 57600,76800,115200,128000,250000,500000,1000000. (The factory default setting is 1000000 bps

4. SCServo can feedback the value of Position , Temperature , Load, Speed and Input Voltage.

5. Also we can reprogram the speed of rotation, the max output torque , operating voltage limit , and o perating temperature limit et c .

6. SCServo can repeat assembly by M2 machine screw, and then use DIY assembly by U bracket.

7. Half D uplex A synchronous C ommunication

Half duplex UART is a serial communication protocol where both TxD and RxD can’t be used at the same time. This method is generally used when many devices need to be connected to a single bus. Since more than one device is connected to the same bus, all the other devices need to be in input mode while one device is transmitting.

The Main Controller that controllers of the SCServo actuators sets the communication direction to input mode, and only when it is transmitting an Instruction Packet, it changes the direction to output mode.

8.Connection to UART

To control the SCServo actuators, the main controller needs to convert its UART signals to the half duplex type. The recommended circuit diagram for this is shown below.
