I’m trying to upgrade our robot to “all-wheel” drive.
We already had a chain drive with a 24 tooth middle sized gear on the motor to the smallest 8 tooth chain drive gear on the wheel back wheel. Which makes for a FAST bot.
This works. But makes it only a rear wheel drive and we also had to slow down the speed via the code to get traction.
I’d like to change it to a chain drive in a triangle with a 32 tooth on the motor to two 16 tooth one on both the front and back wheels. Similar to what is on the Ben Lipper Razorbill or Avalanche (ps. We aren’t building either but that is a good example of the gear build we are shooting for).
When I set the drive up in a triangle. The motor will not even turn the wheels if the robot is on the ground. If I hold it up they will run.
What am I not thinking of?
