Hi everyone,
I'm building a small truck (controlled by a microcontroller) and I'd like to be able to measure the distance it travels. I'm wondering which choice of wheels below produces more accurate distance measurements and which is simpler to implement:
1. DC motors (driven by an H-Bridge IC) with encoders to keep track of the number of revolutions
2. Stepper motors so I can command the anglular displacement of each
The truck should not need to move more than 10 cm/s and will weigh maybe 3-4 kg.
Please let me know if I should provide more information. Thank you!
