Our aim was to power the motors of our bot (which were selected according to the torque requirement of our bot) using a single AAA Battery but due to limited time and and the difficulties in international shipment we are stuck with boosters only available in our country.
The boost converter cannot provided the required current to our motor at it's boosted state even though we are pretty sure that our battery can provide more current, as a result the output voltage of the convertor across the motor drops from 5v to about 0.8v. So we though of using a bunch of them in parallel to solve the issue. Using 5 such boost convertors we saw that this drops from 5v to about 3.8v. So naturally adding more of thes in parallel should be sufficenint to spin the motor at out desired rate. But this seems very sketchy. We tested all this only a single motor and connecting two across the whole configuration will obviously result in a larger drop. So even if we increse the number of boosters from 5 to say 10 there should be a limit where adding more of them stops giving us results. We are reallly hoping it is not the case.
What can we expect going forward or is there something that we are missing from this equation. This is pretty much our last hope
Battery : 1.2 volt 800mah
Boost Convertors : 0.9V ~ 5V to 5V 600MA
NOTE : I should have mentioned it from the start but using a single AAA is a rule in our problem statement that we have to follow. Also the motors are fixed according to our torque requiements
