Today Josh and myself met to plan how we are going to design, build, and program our toy. We need to decide if we want to have the tank launch things using a rubber band as the propellant. Or if we want to launch the rubber band its self. Hopefully we should have that figured out tomorrow. We have decided that in the event that things fall behind schedule, that we will abandon the driving aspects of the tank, and make it into a stationary turret.
We set out a schedule for when we want to have everything finished and created a list of which parts we need to get for this project.
Schedule:
- For November 2nd.
- Work on designs for both firing mechanism ideas
- create a list of parts to order/obtain.
- Nov. 9th: Executive summary finished, decided on a firing mechanism, ordered parts, create
- Executive summary finished.
- Decide on firing mechanism.
- Have all parts for the firing/aiming mechanism
- Create CAD models of all parts that need to be manufactured.
- Decide if we want a moving platform or stationary turret, if yes, then order necessary parts.
- For November 16th:
- Assembly completed for entire project. Wiring completed.
- For November 23rd:
- Completed programming and testing.
- December 4th
- Presentation day.
Annoyingly, Thanksgiving happens to take away the last week of this project, ideally everything is completed the Sunday before thanksgiving, but if we need the extra time, we have the weekend after Thanksgiving.
Parts list
- 4 wheels + drive motors *
- Driving platform*
- Power supply (battery)*
- 2 motor shields
- Stepper motor (for pulling back the rubber-band)+
- Some other motor to change the elevation of the gun+
- smooth metal rod and slider for the cocking mechanism to ride on +
+ means we can get this part from a printer that we might be able to disassemble
* means that it is needed for the drive base.
