After playing with this stuff over the last few months, I have some simple pointers to pass on:
- Test your comms and interfaces before you build the robot. Its a lot easier to test if the wheels turn or not when it doesnt want to launch of the table.
- Know where the center of the servo motors are before you put things together.
- Wheels are easier to configure then tracks, but tracks provide better turning options.
- Read the documentation well before you launch into things, sometimes with hardware there is no undo.
