From my post on “MV Primer” in the tech discussion area of the forum - I want to start a project HERE.
“I have the idea that I would like to make a line following robot for a grid. At each grid intersection could be a symbol so it would have the idea of which node it was approaching and its pose relative to the node. The robot could take instruction to get to the next node or waypoint. In this way it could go from point to point and know where it was and where it is going”.
I have the open mv functioning running example scripts, I have purchased a robot base, AS-2wd from amazon.com. The robot base accepts 5 AA cells- 5 x 1.5v =7.5 volts and has a switch that connects battery + terminal to robot motors charging plug depending on direction of switch.
I am thinking I just to wire a 3.7 lipo battery to power the openmv and operating the robot base from the intended 7.5V.
Can I connect the lipo battery and robot base negative terminals together? I would then route pin 7&8 to the signal pin of each servo. The servos would be powered to the common “-” terminal and the +7.5. The charging switch when flipped I believe would simply charge the 7.5 battery and I would remove and charge the 3.7 lipo. Any commentary would be helpful.
