Warning
When Ned is turned on, do not disconnect the power supply of Ned. You may damage the Raspberry Pi 4 inside Ned, or the micro-SD card.
If you modify the original power supply of the robot, you should respect the same specifications.
Before plugging the power connector and powering on Ned, first make sure that:
Ned is on a flat and stable surface;
The power switch is turned off (position 0);
Ned has enough space to move without hitting something or someone.
Power Switch
The power switch turns Ned on and off. It enables the power supply.
Always switch it off after shutting down Ned and turn it on to power on Ned.
Warning
Before plugging or unplugging the power supply, make sure to turn off the switch.
Do not keep the switch on after shutting down Ned, otherwise , the power will be present on the motors and on the shield
Digital inputs/outputs
Ned has 6 inputs/outputs that can be configured either as digital input or digital output with Niryo Studio (see How to program the digital I/O on the Software Manual).

Ethernet
An Ethernet connection is provided at the panel connector of Ned.
The Ethernet interface can be used for the following:
Modbus TCP/IP;
PyNiryo;
Connect Ned to your local area network.
USB Port
The USB can be used to connect the keyboard, mouse, or Vision Set.
Find more information about Vision Set on the Vision Set Manual.
NiryoStepper connectors
NiryoStepper connectors interface can be used to drive a NiryoStepper motor. It is based on CAN Bus communication protocol.
This interface can be used to drive Niryo’s Conveyor Belt.
DXL connection
Panel LED
Ned’s LED panel has several colors which represent different modes and error status. Refer to the following table:
Color / Blinking |
Description |
Troubleshooting |
|---|---|---|
Solid blue |
Hotspot mode, the robot has started and creates its own Wi-Fi network. |
N/A |
Solid green |
Connected mode, the robot is fully started and connected to a Wi-Fi network. |
N/A |
Alternating between Green/Red |
Motor error on connected mode |
Check “HARDWARE STATUS” and logs to troubleshoot the error. |
Alternating between Blue/Red |

Note
When you pause the robot’s program with the top button, you should either press the button to continue or press twice to stop it.
Hint
You can test your robot hardware for the first time without using any software tool, you can follow the steps below:
Plug the power supply;
Turn on the power switch button;
Wait until the LED panel turns blue (if it is the first time you use Ned this should take 2 minutes);
Press the top button: Ned will start by calibrating and then it will execute a pre-saved sequence.
Tool wiring
Custom Gripper, Large Gripper and Adaptive Gripper:
There is a cable on the tool end of Ned with 3 pins. This connector can drive Custom Gripper, Large Gripper and Adaptive Gripper.
Note
Make sure to respect color order when you are wiring your gripper.
Warning
Not respecting the wiring instructions may damage your gripper or Ned.
Vacuum pump:
Plug the suction cup to Ned’s hand and connect the motor wire to the XL320 Connector placed at the back of Ned.
Electromagnet:
Plug the electromagnet to Ned’s hand and connect the cable on the GPIO1 or GPIO 2 connector on the panel connector.
Note
Information about programming and using the tool are available on the Software Manual
