Following the buzz around the all metal gears option for servos and the possibility of servos with higher torque/high power which appear mentioned in page 4 of wCK manual.
Here is a brief summary of the latest information from Robobuilder:
- High torque versions packs will be released.
However, in practice high torque servos will be regular 1108 and 1111 with ALL METAL GEARS, using higher voltage.
This means that by upgrading to all metal gears you get a High Torque model.
The available torque will vary according to the voltage you supply.
The speed of the servos will also be faster. Here is a comparison chart:
From the chart the highlights are:
1) As you increase the voltage, the available torque and the speed improve.
2) A wCK 1111 with full metal gears at 11V has a torque equivalent to a Bioloid servo.This has been confirmed.
It is also equivalent (slightly superior) to the wCK1113 mentioned in page 4 of the wCK manual.
3) Technically both wCK 1108 and 1111 are similar BUT due to the different gear ratio:
- An 1111 will offer the most torque
- An 1108 is faster at the expense of a lower torque
- At 11V an 1108 will offer a torque equivalent to a standard 1111 while being significantly faster.
With regards to the LiPo upgrade kit, we will supply a LiPo upgrade kit for 11V, so you can take advantage of the higher torque.
Most likely we won't stock LiPo battery packs for the regular 8.4V unless there will be demand for it.
As a final note, page 4 of the wCK manual mention high power servos (wCK 14xx). There are no plans to produce these in the near future.
I am waiting for a quote on the 11V LiPo battery pack so I can add it to the store.
I've also requested to simplify LiPo the assembly method so that it doesn't require soldering. I'm waiting for confirmation on this.
