Week 10: March 21, 2012 (Wednesday)


Hardware - Power Consumption

Today I'm adding a 10 uF capacitor between gnd and vcc pin (+5V) on regulator circuit board for the sensor. 
 
Bypass capacitor (next to the header pin) to stabilize the sensor power supply
 
I ran a test on the Robomouse but it didn’t run smoothly and looks like it is too heavy to move or stuck somewhere. Perhaps the battery is not enough to drive the motor. The battery is sinking so fast and just after a few runs the motors become stall. I switched the supply from battery to power supply from the digital trainer and test run but with the chassis upside down to see if there is something stuck in the wheel but it seems that the wheel run smoothly when it is not touching the ground. So, it is not something to do with the wheel. Still searching for the cause...
