You can connect the 6-Axis Robotic Arm directly to a computer to use to code the Arm without the need for an EXP Brain. The 6-Axis Robotic Arm has a USB-C port that allows it to directly connect to a computer.
On the back of the 6-Axis Robotic Arm's base, you will find three ports. Connect the USB-C into the leftmost port.
The port will have the icon of a USB-C Laptop port beneath it:
Connect the other end of the cable into your computer.
The 6-Axis Arm is now connected to your computer. Before it can be used with VEXcode EXP, you must use the power cable to power on the 6-Axis Robotic Arm.
Once you've connected the power cable to the 6-Axis Robotic Arm, the green light indicator on the back of the 6-Axis Robotic Arm will light up.
