Robobuilder wCK 1111 Servo, Transparent
Please note:
We are currently stocking mostly wCK 1111 servos (limited
availability of 1108 servos). The 1111 servos can be used in place of an 1108 without any
problem.
We chose to keep higher stock quantities of wCK 1111 servos as these already include 3 standard
metal gears (gear 2, 3 and 4), have higher torque, are fully interchangeable with 1108 servos and the price
difference is not too significant. |
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:
11kgf.cm 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).

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)
