Jorge Gonzalez (Tuesday)- Today I did some more programming of the PLC. I added functionality of the pneumatic cylinders controlling the door (open or close), and incorporated the door limit switch so that the Dobot will not pick up or place until the door limit switch is hit (door is open). I progr...

This week I did mostly programming for the PLC program and the HMI program. I worked with Joe to get the HMI to talk to the PLC which talks to the Dobot and Fanuc that ultimately decides if we are taking pots out of the greenhouse, and where, or taking pots into the greenhouse.

Jorge Gonzalez (Tuesday)- Today I installed an emergency stop button, (e-stop), located near the HMI. This stop button is connected to the PLC so that with the PLC we can program certain things to stop or maybe fail open for the door, in case the Dobot tries to pick up a cup from the conveyor. This ...

Jorge Gonzalez This week we added fans to the greenhouse and I helped to run the wiring for those. We have one that intakes cool air and exhausts warm air to cool off the greenhouse if it gets too hot. I got them installed in the PLC running off a 12v power supply, which we had to change to a bigger...

Jorge Gonzalez This week the crew, including myself, prepared the greenhouse. The greenhouse was moved into the other room and I worked with Cole to screw the greenhouse and the Dobot/linear rail into the table. I also fixed some of the wiring issues for the PLC, relays, etc. There was some confusio...

Jorge Gonzalez This week I spent most of the time adding to the PLC program. I finished making the pick and place program and I added a timer for the greenhouse light and pump. Did not get to test it yet because Nick is in the process of wiring everything up and making it look neat so I helped a lit...

Jorge Gonzalez (Tuesday) - Today I worked with Korey and Cole to troubleshoot the input pins on the Dobot. When we tried to send it a 3.3 volt signal, it would read the input as on and off, but we figured out that we need a constant 5 v source to keep the input on. Then we configured another pin to ...

Jorge Gonzalez (Tuesday) -Today I got started on the PLC program for the pick and place locations in the greenhouse. HMI was not working for a while, then I got some help from Chuck to get it running again. Sometimes I still get the error for some unknown reason, but most of the times it seems to wo...

I have completed chapter 1-3 of the textbook

Jorge Gonzalez This week I helped to simulate a "real" application of the Dobot pick and place using my laptop. It worked somewhat but with more variability than we would like. This means we may have to spend more time fine tuning and trying to get the coordinates right each time. The tran...

Jorge Gonzalez I began working on my project on 2/25/2022 I have demonstrated Part 1 and Part 2 with the 7 segment display countdown on 3/10/2022 Part 1 & Part 2 of the project operation has been verified, the extra credit 7-segment display countdown worked as specified. Paperwork has been submi...
