Alert Notation There are six levels of alert notation used in our manuals. In descending order of importance, they are: DANGER: This indicates an imminently hazardous electrical situation which, if not avoided, will result in death or serious injury. DANGER: This indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury.

Payload Structure: Anything you attach to the LD platform. This could be as simple as a box for holding parts or documents that you want transported, or as complicated as a robotic arm that will be used to pick up parts to transport.
It is self-guided and self-charging, with an automated docking station. The LD platform is available in two versions, designed to carry loads up to 60 kg (132 lb) for the LD-60 and 90 kg (198 lb) for the LD-90 platform. Where appropriate, differences between the models are called out.

This laser is mounted beneath the safety laser and offers a 130 degree viewing angle through a cutout at the bottom of the front bumper. It detects obstacles that are low and in front of the LD Platform, such as an empty pallet, which might be too low for the safety scanning laser to see.

The LD Cart Transporter must use a longer wall-mounting bracket to space the dock further from the wall. This is because the rear-facing laser extends past the rear of the LD platform and would interfere with the wall if the standard wall-mounting bracket is used. The base LD Platform can also dock at these locations if your robot fleet contains both LD Cart Transporters and other LD AMRs.
Cart • The cart is a frame mounted on four casters, designed so that it can couple with an LD Platform Cart Transporter. Once coupled, the cart moves with the transporter. When the transporter arrives at the intended goal, it uncouples from the cart and leaves, while the cart remains at the goal. Brakes automatically engage on the cart casters upon uncoupling, preventing it from rolling in case the floor isn’t completely level.

The LD Platform-based mobile robots are designed for operating in industrial or professional environments. They must be deployed in a manner that takes into account potential risks to personnel and equipment.

The robot may also encounter overhanging obstacles. These may be visible to its optional side lasers (standard with the LD Cart Transporter), but logical barriers should still be used to prevent the robot from planning a path through that space. If side-lasers are not used, of if they cannot detect the overhanging obstacle when the AMR is far enough away to prevent collision, then physical barriers must be used in addition to logical barriers to prevent this hazard.

Configurable Warning Buzzer The LD platforms have a configurable warning buzzer. It is the user’s responsibility to configure this buzzer as appropriate for the facility in which the robot will be operating. The buzzer will sound whenever the robot is moving backwards or is turning. Other situations are configurable.

Use in such areas may require deployment of additional safety measures. Clearance The LD platform is designed to operate in an environment that is generally level and has no doors or other restricted areas too narrow for the AMR. It is the user’s responsibility to ensure that adequate clearance is maintained on each side of the AMR, so that a person cannot get trapped between the AMR and a wall or other fixed object.
• Robot Modifications If the user or integrator makes any changes to the LD platform or cart, it is their responsibility to ensure that there are no sharp edges, corners, or protrusions. Note that any change to the platform or cart can lead to loss in safety or functionality. It is the responsibility of the user or integrator to ensure that all safety features are operational after modifications.
Omron as manufacturer are aware of our duties and responsibilities regarding the development, manufacturing and placing of safe mobile robots on the market and consistently implement them. However, Omron have no direct influence on the usage of our mobile robots. As a precaution, we point out the following:...

Emergency Stop Circuit Theory of operation The emergency stop (E-STOP) is the most basic safety function of the LD Series robot and is a good starting point to overview the safety systems. The vehicle has six basic E-STOP sources. Sources 1, 2, and 3 are visible from outside the vehicle. Sources 4 and 5 are either internal function or user connected inputs.

Side Lasers Introduction Side lasers are optional for users building their own AMR from the LD Platform, and come pre- installed on the LD Cart Transporter models. This chapter covers installation on base LD models only. Side Lasers scan in a vertical plane near the path of the robot, allowing the AMR to detect obstacles at other heights that the AMR must avoid.
Robot Physical > Laser_3 and Robot Physical > Laser_4. Configuring the side lasers is generally performed by importing the factory-supplied configuration into the AMR’s current configuration. Contact Omron for assistance. For Laser_3 (right) and Laser_4 (left), the relevant parameters are: LaserAutoConnect: Should be checked to turn on the laser.

If your environment has a restricted number of possible robot paths, this number should stay relatively large, such as thirty seconds, so that the robot does not rediscover the same obstacle multiple times. Contact your local Omron Support if you have difficulty tuning these parameters for your environment.

AMR is moving in reverse, or when the safety systems are off, for example, when the platform is moving at a speed lower then 300 mm/s (225 mm/s for the LD-90 and LD CT-105 models). The warning buzzer’s behavior is configurable by the user, so it can be used to sound, for example, whenever the AMR is moving.

Take care to keep all of the payload structure higher than the top of the LD platform. If any of the platform's sensors get blocked, it won't be able to function normally. This is critical in the case of the safety scanning laser.

Figure 6: Platform Deck Dimensions, for Attaching Payload Structure with M6-threaded bolts In the preceding figure, all of the M6 PEM nuts (A) have a torque limit of 3 N-m (26.6 in-lbf). CAUTION: Do not exceed this torque when attaching your payload structure to these PEM nuts.
Page 37
Center of Gravity As much as possible, you should keep the payload structure center of gravity centered on the LD platform, and as low (close to the platform top) as possible. This will give you the best stability, particularly when crossing thresholds or irregularities in the floor.
Page 38
IMPORTANT: Applications for which the CG cannot be maintained within these limits are not supported. OMRON recommends against such changes. In the following three figures, light blue represents the payload structure, while dark blue represents the LD robot.
