Keep in mind that these have to automatically reset.

I think one idea Matt mentioned during the presentation would be to have a non-broken bottle with a target, be replaced by a broken bottle with the single pop of a strobe. You could picture it being on a rotary actuator, and have it 'snap' around. Just a thought. The less moving parts, the less things that can be bent, worn and broken, the better.

I like the concept a lot that you're getting into. I would love to see this explore some more of the technical challenges. Could you try with a real linear actuator? Maybe with a read servo motor? Even if the pieces are still cardboard, there could be some value to try some of this out.

It would have been nice to have a little video showing this in action. Is the rubber band in tension when the bottle is up or down? I can't see the rubber band in the images, it would be nice to have labels to point out the components.

The sketch model explores the mechanism for how a target would flip itself when hit by a light beam. Two mechanical approaches were explored, but not in a great detail. I would have liked to seen the integration with the mechanical and electromechanical components, but it seems that no electronics were involved. What is really important to investigate is the suitable amount of time for a target to drop for the experience to feel realistic. Another approach that could be considered is to have the target simply move up and down through a slot on the surface - rather than having it rotate by 90 degrees.

I like that you explored two different methods, I think this will be especially valuable down the road if you pursue this as your final project. If I understand it correctly, you won't be actually shooting anything at the targets, it will all be done electronically (at least I hope this is the case). I like the simplicity of the second design a little bit better, constraining moving parts to only one dimension. I wonder how smooth this would look as it's going up and down, as the torsional spring seems like it would move a little more naturally than this design. If you haven't already, definitely look into how carnival games/amusements parks do this with similar games.

I love the simplicity of the concept explored by the sketch model. My only concern would be how robust it would be if a torsional spring is used. Why not utilize a motor to rotate the target up and down? Even if a torsional spring is used, some mechanism is still required to push it upright to reset the target.

Alternatively, you can make the concept even simpler by making an LED light up above the target to indicate that the target has been shot. This means that no moving parts are even required.

Great little model! I think you might have done well to take it just a little bit past the pushpin-and-rubber-band stage, though.

Nicely done though. In this scope, this looks nice.

Do you plan on hooking this setup with a microcontroller to test the laser beam into a sensor that then triggers the actuation of the piston that you mentioned? I think Model 2 is better suited for the storyboard as it doesn't have such a bulky box next to it, so it is more immersive.

The execution of the mechanical components was done well, but I find the works-like insufficient without incorporating electromechanical actuators.

As I said above, I like how you explored two methods to see which would perform the best. The model is simple, but being a works-like explores a critical question that you are attempting to answer. I think the next step would be to adapt electronics onto this model to see what the feasibility of motors or other components is. I think you're on the right track, overall, good job!

I think the sketch model is well executed by using very simple materials. It keeps in line to how sketch models should be easy to modify and change while still retaining the core concept of the looks like and works like model.
