TuskE (CE version) pallet robot has built a set of all-weather safety protection system for high-risk operation scenarios through PLd-level safety architecture design and long-life battery system. The following is an analysis from three dimensions: safety protection technology, battery performance support, and actual application verification:

1. PLd-level safety protection: engineering implementation of the world's highest safety standard

PLd is the "high reliability safety level" defined in the EN ISO 13849-1 standard, which must meet multiple stringent requirements such as hardware redundancy, fault detection, and system fault tolerance. TuskE achieves PLd-level protection through the following technologies:

(1) Hardware redundancy design
Multi-sensor fusion obstacle avoidance: front/rear dual laser sensors cover 360° detection (detection distance 0-3 meters), combined with the fork tip photoelectric sensor (≤100mm accuracy) and collision switch, to form a three-level obstacle avoidance logic (warning → deceleration → emergency stop).

Double emergency braking mechanism: The physical emergency stop button is interlocked with the software trigger to ensure complete stop within 0.5 seconds in case of human intervention or system failure.

(2) Software safety logic
Dynamic path planning algorithm: Real-time fusion of laser data and task priority to avoid blind spot collisions. For example, in the dense warehousing scenarios of the 3C industry, the WMS system is integrated to optimize the path to reduce the risk of mixed human-machine operations.
Safety status self-check: Automatically check the sensor, communication module, and battery status at startup, trigger an audible and visual alarm and lock the operation when abnormal.

(3) Mechanical protection reinforcement
The body is wrapped with high-strength protective strips, and the fork structure has been optimized through finite element analysis. It can still withstand unexpected impacts under a full load of 800kg.

2. 1500-cycle battery: the energy cornerstone of all-weather operation

The lithium-ion battery system equipped with TuskE ensures the reliability and economy of 7×24-hour continuous operation through long-life design and intelligent management:

(1) Battery core technical parameters
Cycle life: The capacity is ≥70% after 1500 charge and discharge cycles, far exceeding the industry average of 1000 times.
Fast charging and battery replacement: supports 2.5-hour fast charging (refer to similar PTE series battery technology), and optional hot-swappable batteries can be used to achieve "battery replacement without stopping the machine".

Accurate power management: SOC (battery status) measurement error <1%, avoiding task interruption due to misjudgment of power.

(2) Safety and environmental protection design
Triple hardware protection: overcurrent/overvoltage/short circuit/undervoltage/overtemperature protection module integration, UN38.3 certification, eliminate the risk of thermal runaway.
Low-carbon operation and maintenance: calculated by charging and discharging twice a day, a single battery can support more than 2 years of use, reducing battery replacement costs by 30%.

3. Systematic adaptation solutions for high-risk scenarios

TuskE further enhances safety and stability in high-risk environments through customized scenario configuration and intelligent scheduling system:

(1) Mixed traffic management
In 3C electronic warehouses, the Farseer visual system is used to identify dynamic obstacles in real time, and combined with dual-frequency communication (2.4G/5G) to achieve millisecond-level command response.

(2) Response to extreme working conditions
The fork floating height adjustment function of ±7mm is suitable for uneven ground or pallet deformation scenarios to avoid rollover caused by mechanical jamming.
The natural cooling battery system can operate stably in an environment of -10~55℃, meeting the needs of special scenarios such as cold chain logistics.

(3) Data-driven preventive maintenance
The intelligent management platform records data such as battery health and sensor loss rate to warn of potential faults in advance. For example, when the laser sensor calibration deviation is >5%, a maintenance work order is automatically triggered.
