Can-can Challenge


So, week 18 finally came. It's the Can-can Challenge week. Let us just s
ummarise the "journey" to the can-can challenge.

In Singapore Polytechnic, we use the CDIO process. CDIO stands for Conceive Design Implement Operate. The CDIO process is very useful for our can can challenge.

Here's the details of the can can challenge. We are provided with a complete base chassis consists of 2 continuous servo motors, micro controller, 3 spacers and batteries. In addition, 1 positional servo motor and polycarbonate plate is provided.

Here are some of the rules of the can can challenge:

  • Robot needs to move 500mm to bring an empty can of Ø70mm back to the start line as quickly as possible.
  • 3 trails for each team, 2 minutes per trial, highest number of cans will be chosen.
  • The team with the highest number of cans collected wins.
  • The robot must be within a perimeter of 400x300x300mm.

So, here's our journey of the project:

First up is the 'C' which stands for Conceive. It simply means brainstorming. In brainstorming, we came up with some ideas.

Our brainstorming ideas and the design of the plate  are being drafted here.

This is the mechanism plate that we intend to do.

Second is the 'D' which is design

The finalise arm and the plate that we intend to do.

Thirdly, 'I' which is Implement. 

Indicating the place on the acrylic before cutting the arm.



The arm after it has been cut, but it's not done yet.




The arm, fully cut like the way we wanted. there is the metal shin on the tip of the arm because it accidentally broke when we cut it out.



This is the servo plate that we have cut out, but not finalise.


The finalise servo plate.


And after fabricating, this is what we got:

This is the arm


This is the servo plate



This is the extension to the servo plate to screw the servo plate to the car

This is the servo screwed to the servo plate



This is the servo screwed to the extension plate and the servo plate

This is the arm, servo plate, plate extension, and the servo screwed together



And finally, this is the components with the car.



Lastly, it's the 'O' which is Operate. Here's a short clip of the operation.


In the end, we manage to win the challenge by collecting a total of 10 cans. All of our efforts has paid off. Thank you teacher for your guidance. :)

Cheers.

    2 August 2011

    for this session, we manage to improvise the product. As the can can challenge is coming in 2 weeks time, we decide to use the lab during it's free access time to finish off our work.


    Both of these pictures are the arm. we screw the acrylic with  shin metal because the arm broke at one of the point.

    We manage to drill hole so that the servo can be screwed to this holder.
