Need help starting College-level design project
I'm an engineering professor and want to modify our Engineering Design freshman course to include a microcontroller-based design project in the coming semester. We have traditionally utilized a design project which is strictly "mechanical" in nature.
My desire is to develop a project using the Arduino microcontroller to control a robotic car to follow a black-tape track which I will place on the floor. This is nothing new, since I have seen videos on this site which do exactly that. My class consists of four student teams who must each develop their own robotic car. I need help with the parts my college will have to buy to support this new design project. We wil loan out the needed parts to each team.
Here is what I have come up with so far (by looking over the Adafruit site):
- 4 Arduino experimentation kits
- 4 motor/stepper/servo shields
- 4 drive motors (they will need to have some kind of gearbox to reduce output rpm)
- 4 servos to drive a steering mechanism
- 12 (or possibly more) optical sensors or photocells to detect black tape on the floor
- 4 power transistors
- a large pack of resistors, capacitors, diodes, microswitches, pots etc.
- 4 battery cases
- 4 stepper motors (may be needed, if servos can't do the job)
- small reed relays???
Can you provide recommendations on what to buy? Do I have too much listed or am I missing some things? My school's budget is limted since it is a Community College with limited funds.
Thanks for any help you can provide.
