Application Technology Xe tự hành

Material handling automatization

• Automated guided vehicle / Autonomous Mobile Robot replace equipment that requires an operator/driver and mitigate the labor issue.
• Multiple functions application-dependant: Fork lift, load a pallet, adjust the height, carry a roll or a train of roll
• Multiple indoor location: Warehouse, logistic floor, production floor, Ambient, cold or frozen temperature up to -28 °C
• Automated vehicle are Electrical Battery Vehicle and follow the 48 VDC trend : lower current, better efficiency, lower cost, quicker charge
• Work 7/7 24h
• Safe, accurate, efficient
• Highly Monitored / IoT
