A 7-DOF robot with human-like agility
The myArm 300 Pi is an integrated 7-DOF robot that uses the Raspberry Pi 4B as its main control
board. It is paired with the Ubuntu Mate 20.04 OS, specifically customized for robots by ElephantRobotics. No additional PC controller is needed. By simply connecting a monitor, keyboard, and mouse,users can easily start basic development. This ensures that the robot no longer requires an externalcontroller but still provides an experience similar to a desktop PC.

Warranty Coverage
During the warranty period, should any component experience issues, we will handle it according to the respective warranty policy of the component. As ourrobotic products comprise various components, the after-sales warranty period might differ among them. We encourage you to carefully read the after-sales
policy of the corresponding components to avoid misunderstandings.
1. Within the warranty period, if there are instances of product malfunction due to manufacturing defects that prevent normal use as per the usage
instructions, our company offers one-time free after-sales repair services (including, but not limited to,replacement or repair of the correspondingcomponents). This ensures the product can function as expected, with all shipping and material costs being borne by our company.

Warranty Exceptions
