Safety Overview

This section includes information on general safety risks to be considered when performing installation and service work on Ned.

These safety instructions must be read and followed by any person who deals with Ned.

Spare parts and special equipment

The installation and the use of external components is possible (such as Arduino, external sensors, devices). But the user must respect the electrical specifications and connections mentioned in the User Manual.

Niryo is not liable for damages or injuries caused by unauthorized modifications to the robot system or the misuse of the robot.

Complete robot

Danger

  1. Before installing, using, or programming Ned, read the product specifications and Manual;

  2. Make sure to install Ned and all electrical equipment according to the specifications and the warnings from chapters Installation and commissioning and Technical specifications;

  3. Children are not allowed to operate Ned without adult supervision to prevent any possible injury or improper misuse of Ned;

  4. Make sure that changing robot software will not cause hazards, damages to the Ned’s system or injuries.

Warning

  1. Motors and gearboxes are hot after running Ned for a long time. Avoid touching especially with a higher environment temperature;

  2. Removing parts may result in the collapse of Ned. Take the necessary measures to ensure that Ned does not collapse as parts are removed;

  3. Make sure to remove the power cable during assembly, wiring, or repair. Doing so will help to prevent equipment damage or accidental short-circuit;

  4. The cable packages may be sensitive to mechanical damage;

  5. Before using Ned, make sure to firmly fix it on a stable surface to avoid collapse or the fall of Ned;

  6. Do not use Ned outside;

  7. Do not put Ned in a humid environment or near water;

  8. Do not install or operate Ned in dangerous environments (e.g., in the presence a strong magnetic field, dangerous gases, fire or flammables) to avoid dangers which may occur due to external conditions during operation;

  9. Respect the technical specifications to avoid damaging the motors. Stepper motors and servo motors may be damaged if excessive force is used;

  10. Make sure external change on the motors parameters or the robot software does not cause damage to Ned.

  11. Do not open Ned base when the power cable is connected. Do not touch the electronic board, they may be hot.

Niryo is not liable for damages or injuries caused by unauthorized modifications to the robot system or the misuse of the robot.

Caution

  1. Do not turn off Ned during a sequence or a motion unless absolutely necessary, this may reduce Ned operating age;

  2. Try to install Ned arm on a stable surface with enough space to avoid any shock or vibration.

Safety actions

  • Fire extinguishing

Note

Use a CARBON DIOXIDE (CO2) extinguisher in the event of a fire in Ned’s system.

  • Manually stopping or overriding the arm: if needed, Ned arm can be stopped manually. This is possible since Ned arm is light, the arm force is limited, and the drivetrain power is limited.

To prevent unnecessary damage and wear of Ned arm, it is recommended to use the normal stopping functions of Ned (by the software or the top button).

Note

Ned is not equipped with brakes since its weight and design do not require a holding brake.
