Advantages

*

Under no-load conditions and an ambient temperature of 25°C,when the output shaft speed is 0,measurement values for different modules may vary. These data are for reference only.

**

For collaborative robots with a 10kg load,under normal operating conditions, the surface temperature of the sixth axis may vary between different modules and environments.These values are for reference only.

***

Based on the lifespan calculation formula taking the fourth axis of a 10kg collaborative robot as an example:

Due to the reduced weight of the last three eRob80 joints,the load on the fourth axis decreases, thereby enhancing its lifespan:

The lifespan of the eRob 80I V6 can be increased by 9.5%.

Reference: HarmonicDrive Reducer Catalog, formula 012-1, PP.12.

Allows for straight-through robot arm design

More suitable for humanoid robots, bionic robots, and collaborative robots

Version Differentiation

Step 1:Check the back cover of the module and find a line with "V6" as shown below.

Step 2:If the prefix is "V5", the module is version V5; if the prefix is "V6",the module is version V6.
