These past two weeks, we have been working on getting the robot to pick up a box every time. We integrated the vision/control algos with the robot kinematic algorithms and were able to reliably pick up multiple boxes in a row. Physically, we updated the arm to have both arm and electronic controllers on the same 3d printed structure/piece. We were able to sync the main PC program’s axes/commands almost perfectly with the arm’s angle quirks to maximize accuracy. We were able to test the system on example boxes running on the treadmill and achieve 80% pickup success (8/10 runs). We have already started experimenting with different pickup move paths / command sequencing, as well as experimenting with different refresh rates and power ramping for the servo. Next week we are going to work on dialing in arm movement and test our system with real drop-off bins.
