Regular training sessions and safety drills should be conducted to ensure staff are prepared for emergencies. It is important to communicate these protocols to all warehouse staff and regularly review and update them to maximize effectiveness.
Choosing the Right Autonomous Industrial Vehicles
With a wide range of industrial autonomous vehicles available in the market, how do you determine the best choice? Selecting the right industrial AV solution to optimize safety in your warehouse is crucial. Therefore, operators need to carefully consider the capabilities and limitations of each vehicle before making the switch.
Evaluating Vehicle Capabilities and Limitations
First, assess the vehicle's capabilities, including weight capacity, speed, and adaptability, to ensure they align with your specific application. For instance, if the AV will be used for transporting heavy materials, it is important to choose a vehicle with a high weight capacity. Specifically at Cyngn, our autonomous stock chaser offers a high maximum towing capacity of 6,000 lbs making it ideal for moving heavy items. Similarly, if the vehicle needs to navigate tight spaces, it is essential to choose a vehicle with excellent maneuverability.
Operators should also consider potential limitations, such as battery life and sensor capabilities, as these factors can affect the vehicle's performance. Your organization should choose a vehicle with a battery that lasts long enough for the required tasks without frequent recharging. Additionally, evaluating the sensors ensures that the vehicle can detect obstacles, navigate the warehouse safely, and maintain a proper distance from people and objects.
Selecting Vehicles with Advanced Safety Features
Autonomous vehicles equipped with advanced safety features such as collision avoidance systems should be prioritized. Specifically, these types of features can help prevent accidents and reduce the risk of harm to personnel and equipment. Other safety features to consider include emergency stop buttons and obstacle detection sensors.
Organization’s should further consider the vehicle’s ability to operate safely in different environments. For example, if the vehicle is driving in an area with low visibility, it is important to choose a vehicle with advanced sensors that can accurately detect obstacles and adjust its speed accordingly.
At Cyngn, for instance, every aspect of our AV technology was built with safety in mind. The system is equipped with multiple sensors, communication lights, and hardware and software redundancies to keep workers safe.
Specifically, we have implemented the third tier of our perception stack known as the "virtual bumper”. This redundant sensor and compute package on our autonomous vehicles provides an additional layer of safety. In the event that something occurs in the environment that either is unexpected or unsafe, we can be sure that we have redundancy built into the vehicle.
