time flies, and soon it is deadline for contest.
today i am assembling the 'weapon' of the robot, the motorized scissor. First, i want to choose a suitable motor to drive the scissor
i dig from my collection and found this Tamiya motor set, and assemble it with 4:1 ratio
Then we do a simple test with power supply, driving both motor at 3V (low enough so that i can directly drive it from the Nucleo 64 later

i find that the Tamiya motor draw 1A, and runs much faster than the motor i salvage from a 4WD chasis.
I decide to use the smaller motor, that only draws 0.1A and runs much smaller but suitable for scissor speed.
