I'm a teacher and I'd like to build a very simple two wheel robot as a continuation of an Arduino introduction in a high school course. So far we've used Arduino with LEDs only. I'd like to get into something more exciting like driving motors and using sensors to either avoid obstacles or following a line (btw which is easier?).
We already have Arduino boards (and wifi shiels) but no mechanical parts. I'd like to build a cheap prototype with my students this year and, if all goes well, build some more next years.
I made some research and found there is no "mainstream" cheap kit in that field and I don't know exactly what my requirements are. I guess I need:
- a motor shield
- two gearmotors
- some chassis with wheels
Could you recommend me some of these parts?
I've also been looking in some kits like:
- DFRobot 2WD(turtle) mobile platform
- Dagu Rover5
- Sparkfun Magician Chassis
- Sparkfun Protosnap Minibot kit
Should I go for some of them instead?
