AFSR: Test End-Effector, App, and AR Experiment

We worked on three things for the Automatic Food Slicer Robot‘s latest update.

A toothpick tool as a test end-effector, an app to interface with the robot, and experimented with AR marker tracking.

Watch the video to learn about the update!

Coming up soon will be a teardown of some hardware, it will be pretty cool. Until next time, working more on this project! (Lots more to work on)

AFSR: Z-Axis Carriage Progress (Part 3)

In our latest adventures of the Automatic Food Slicer Robot, we continued to work on the encoder- coming up with code to move its position by a given number of ticks.

We also added buttons to detect when the gear set hits the ends.

The most challenging part of this update was figuring out that the motor was overshooting the encoder by 1-2 ticks, and trying to fix this.

The drive gear broke, so we created a new one:

AFSR: Z-Axis Carriage Progress (Part 2)

In our latest adventures of the Automatic Food Slicer Robot, we advanced further into the build of this sub-assembly. Now the Z-Axis can slide along the racks, and we started creating the DIY encoder.

The most challenging part of this update was getting the DIY encoder set up to show different readings for the dark/light stripes.

We also solved the existing rack warping problem.
