AUTONOMOUS VEHICLES PLATFORM

AUTONOMOUS VEHICLES PLATFORM

AGVs (Automated Guided Vehicles) are the core of ASTI’s business.
ASTI offers a comprehensive range of AGVs divided into three product lines: EasyBot, RoboFast and HardBot.

EASYBOTS
WHAT IS EASYBOT?

specially designed for the automotive industry,these AGVs tow the load on a series of trailers.Simpleto use,they maximise assembly line automation.EasyBot systems employ a combination of magnetic guidanceand RFID technology to mark out the route and the loading and unloading stations.

TYPES OF EASYBOTS

EasyBots come in five versions:
Basic: Small-size AGV.
Standard: Standard AGV.
Bidibot: Capable of bidirectional movement.
Omnibot: Capable of omnidirectional movement.
Tribot: Used to tow heavy loads and can be deployed in outdoor environments.

ROBOFAST
WHAT IS ROBOFAST?

Principally designed to automate palletised load handling, these AGVs’ flexibility and wide range of configurationsmake them ideal for automating transport of other loads like containers, racks, crates and other non-standard units.

TYPES OF ROBOFAST

They are based on the following commercially available conventional vehicles:
Pallet truck: Used to carry palletised loads. No stacking capability.
Stacker: Used to carry heavy palletised loads. The forks have a vertical range of several metres.
Counterbalanced truck: Equipped with a counterweight to allow it to carry heavy palletised loads. The forks have a vertical range of several metres.
Reach truck: used to carry extremely heavy palletised loads. The forks have a vertical range of several metresand can be extended and retracted to increase pallet-handling capability.

HARDBOTS
WHAT IS HARDBOT?

AGVs specially designed to carry large, heavy loadsweighing up to several tonnes.

TECHNOLOGY OF AGVs

TECHNOLOGY OF AGVs

ASTI’s AGV technology is built on 5 modules.

  • Standard pallet trucks: designed to carry palletised loads.
  • Standard tractor units: specially designed to tow trailers weighing up to 8 tonnes.
  • Standard food-grade pallet trucks: specially designed for sectors like the food industry, where hygiene regulations stipulate that all elements in contact with food must be made of stainless steel.
  • Custom-built AGVs: for when the solution requires bespoke design:
    • Lightweight: vehicles specially designed to carry light loads.
    • Heavy duty: vehicles specially designed to carry any size load weighing up to several tonnes.These AGVs are designed for the aerospace sector in particular, where the loads carried are frequently larger and heavier than in other industries.
    • Food-grade: vehicles specially designed to carry foodstuffs in a sector in which use of stainless steel is mandatory.
  • Wire-guided: the AGV follows a route marked by a cable inserted in the floor.
  • Magnetic: the AGV follows a route marked by a magnetic strip or magnetic tags.
  • Optical: the AGV follows a route marked by a painted strip detected by an onboard camera.
  • Laser: reflectors installed at strategic locations within the plant ensure that wherever the AGV is on the lay-out it can detect three reflections of the laser beam its navigation module emits, allowing the AGV to determine its position with pinpoint accuracy.
  • Natural / outline: the system uses the position of objects within the plant to create virtual maps and routes.
  • Combined: as AGV routes sometimes cross widely differing areas, it can be necessary to combine various navigation systems to optimise positioning on every section of the lay-out.These dual guidance systems work seamlessly, switching from one mode to the other depending on the vehicle’s position on the lay-out.

ASTI’s AGV safety systems employ the following technologies:

  • Safety laser: device capable of detecting obstacles, slowing the vehicle and stopping it at a safedistance. Fully configurable according to specific project requirements.Also includes curtain-type lasers for overhead safety.
  • Photocells + bumper: active safety systems that enable safe load collection.Installed around the vehicle’s perimeter, safety photocells stop the vehicle as soon as they detect an obstacle.Bumpers work in a similar way, stopping the vehicle when they come into contact with an obstacle.
  • Acoustic and luminous warnings: these warn other users in the plant of the AGV’s presence.
  • Emergency stop: used to halt the vehicle manually when danger is imminent.

ASTI’s AGVs can be fitted with:

  • Lithium-ion
  • Gel
  • Lead-acid batteries
Three recharging options are available:
  • manual swap
  • automatic recharge
  • online recharge (the latter partially recharges the batteries whenever the system is inactive).

This system’s key components are as followss:

  • Data capture system: collects information about the status of the facility’s components.
  • Host: the heart of the communication system,it manages all the signals generated in the plant and issues the AGVs’ work orders.
  • Traffic management system: manages vehicle stoppages in facilities equipped with more than one AGVand prevents unnecessary halts to optimise productivity.
