AEE Project : Automatic Metal Filings Evacuator

Group:

  • RINGUET Gaëtan
  • MAIRESSE Andrew
  • GOOSSENS Nicolas
  • CATINUS Florence
  • MARASCHIELLO Anthony

Description:

A wheeled robot will be used to evacuate a container full of metal fillings from the machining post to the garbage’s post. The robot also have to replace the full container by an empty one to make sure an empty container is always available at the machining post (so that the machining process does not have to be stopped) .

The containers will be designed as rolling trailers (like a truck trailer).

Objectives:

  • Avoid human resources for this job
  • Automate the process
  • Always have an empty container at the machining postUse an autonomous robot to drive the trailers to the right place at the right time.The robot must be powerful enough to displace a full container. He also has to take enough energy on board to carry out a complete cycle without any problem.Use an easy and safe (un)locking system for the trailers.
  • The displacements have to be precise to avoid the operator to move the loaded trailer when he has to lock it on the robot.
  • The robot should be able to follow a path to arrive to the right destination.

Constraints:

  • Use an autonomous robot to drive the trailers to the right place at the right time.
  • The robot should be able to follow a path to arrive to the right destination.
  • The robot must be powerful enough to displace a full container. He also has to take enough energy on board to carry out a complete cycle without any problem.
  • The displacements have to be precise to avoid the operator to move the loaded trailer when he has to lock it on the robot.
  • Use an easy and safe (un)locking system for the trailers.

Planned electrotechnical equipment:

  • Wheeled robot drived by Arduino
  • 2 DC motors to drive the robot
  • 3 Trailers
  • Battery and battery charger
  • Bluetooth Emmitter/Receiver
  • light sensor (color sensor)

diagram and explanation:

The robot stands at the power station where its batteries are reloaded. The container of its trailer is empty.

When the operator of the machining post needs an empty container he sends a signal to the robot (wireless signal). Then the robot leaves its power station and goes to the machining post.

There, he parks its empty trailer on a first parking place. The operator unlocks the trailer and the robot moves to a second parking place where the operator locks the full container.

The robot drives its new trailer to the garbage’s station where it swaps its trailer for an empty one (like at the machining post).

The robot then returns to the power station and stays there until he receives a new order.

To move between each post, the robot will be guided by a colored path on the ground.

Different sensors will be used to inform the robot of the state of its container (locked, unlocked, full, empty,…). An electrical motor will be used for the propulsion of the robot, and probably another to its direction system
