Balanced Carbot is More Sprightly
I couldn’t do exactly what I thought but this is close and it proves the point. With lighter batteries moved to behind the rear axle carbot moves and turns much better. The turn is still a bit iffy but it’s good enough to not be actually discouraging. The next trick will be to get a sensor working and see if it will do a controlled turn. I’m using two AAs for the logic supply and the 3 cell phone battery pack for the motor drive. The total weight is 420 grams with 90 on the front and 330 on the rear. I can pretty easily trim 20 grams off the total by going to AAAs or lithium AAs for the logic supply but I guess that might actually increase the weight on the front wheels since those batteries are right at the back.
Things I weighed today:
- Revised Carbot 420 grams
- Two cell AA power pack 66 grams
- Single AA alkaline or nimh 25 grams
- Single AA lithium 15 grams
- Single alkaline AAA 11 grams
