Quick overview

Robobuilder wCK 1111 Servo, Transparent

Robobuilder wCK 1111 Servo, Transparent

The servo line-up from Robobuilder offer PID motion control, Serial Communication, 1 Analogue port and an Extended Protocol for complete control and configuration. Additionally the servo has transparent cover (exposing the inner workings of the servo) and comes with two coloured LEDs (controllable via the servo protocol).
The servo is controlled over a UART TTL serial line, meaning it can be controlled from a wide variety of devices, including the PC (using the appropriate RS232 or USB to TTL converter) and uses standard 2 byte instruction packets for control and feedback.

Servo Features:
  • Holding torque: at 8.4V
  • No-Load Speed: 0,25 sec/60 deg at 8.4V
  • Operating Angle: 0~269º (Standard Resolution); 0~333º (High Resolution);
    Additionally the servo can perform full rotation (360º) acting like a DC motor (with adjustable speed)
  • Resolution: 8 bit/1.055º (Standard Resolution); 10 bit/0.325º (High Resolution)
  • Position error: less than 1 degree; Average error 0.33 degree
  • Recommended Operating Voltage ~8.4V
  • 3 power states: Holding Torque; Free Motion (no torque) and Dynamic Brake where the servo offers some torque but uses no power at all.
           Servo Protocol Features:
  • Each servo is assigned its own ID is address through 2 byte instruction packets
  • 8bit and 10 bit position Read (feedback) and Position Set commands
  • Instructions for Reading the Analogue Port and read/write to the DIO ports.
  • Instructions to adjust / tweak PID configuration
  • Multiple configuration options for speed, acceleration, etc. (reffer to the manual for a full list)
  • 360 deg mode: the servo can perform full rotations behaving like an intelligent DC motor with adjustable speed
  • Additional instructions are available to program the servo for stand alone operation (self running motions). In this operation mode the servo can be programmed to perform simple actions and react to external events (such as the DIO and Analogue ports).
  • PID motion control
  • TTL UART Serial Interface (4 800bps~921 600 bps)
  • Self running motion (stand alone operation)
  • Colour: Transparent
  • 2 Coloured Leds (One Blue + One Pink)
  • Gear Type: Gear 1 in Plastic;
    Gears 2, 3 & 4 in Metal
    (The meaning of Gear Numbers can be consulted here

I/O ports and Assembly System:

  • 1 Analog Input Port (servo exposes solder pads to connect any 0~5V analogue sensor)
  • 2 DIO ports: in this model, these ports are used by the two colored LEDs
    LEDs can be turned on or off by setting each DIO port to 1 or 0 using the Servo Protocol.
  • Joint-insert assembly for quick and easy assembly and prototyping
    (you can purchase optional joint sets for fast creation of prototypes and robots)
