Adam uses stepper motors and DC motors to launch cheeseballs and move the launcher in the X and Y-axis. A Raspberry Pi4, OpenCV, and an ultrasonic sensor were used to predict where to launch cheeseballs. Watch Adam build a completely absurd face-tracking cheeseball launcher, so we can inevitably be lazier. </span></p> <p style="margin:0;padding:0px;">&nbsp;</p> <h2 id="mcetoc_1flne7juk0"><span

you are lazy and unwilling to move, how do you get food, especially cheesy goodness? Adam uses stepper motors and DC motors to launch cheeseballs and move the launcher in the X and Y-axis. A Raspberry Pi4, OpenCV, and an ultrasonic sensor were used to predict where to launch cheeseballs. Watch Adam build a completely absurd face-tracking cheeseball launcher, so we can inevitably be lazier. </span></p> <p style="margin:0;padding:0px;">&nbsp;</p> <h2 id="mcetoc_1flne7juk0"><span

move, how do you get food, especially cheesy goodness? Adam uses stepper motors and DC motors to launch cheeseballs and move the launcher in the X and Y-axis. A Raspberry Pi4, OpenCV, and an ultrasonic sensor were used to predict where to launch cheeseballs. Watch Adam build a completely absurd face-tracking cheeseball launcher, so we can inevitably be lazier. </span></p><p style="margin:0;padding:0px;">&nbsp;</p><h2><span style="color:#3334ca;">Bill of
