What we did:

Wired the cut-off switches and ran wire to attach to the sensors.

We have the rf remote connected and working with the Arduino.

What we didn’t do:

Still need to mount the Ultrasonic sensors to the bottom of the shelf. We have them working with the Arduino but they just need to be installed.

Where we are stuck:

 

Upcoming Week

Goals:

Current Week

Individual Hours:

All members met during team meeting.

What we did:

We’ve attached the cut-off switches to the shelf. Testing was successful.

We coded the Arduino so that reversing the shelf overrides the cut-off switches.

We made a plexiglass sheet to which we can mount the sensors.

The sensors have come in and we got them working with the Arduino.

What we didn’t do:

We haven’t mounted the sensors, yet.

We’re still waiting for the rf remote to come in.

Where we are stuck:

 

Upcoming Week

Goals:

Mount the sensors.

Wire the cut-off switches and sensors.

Install the RF receiver.

Package the Arduino.

Current Week

Individual Hours:

 All members met during team meetings.

What we did:

Ordered RF remote.

Continued working on the relay. We now have it working with the shelf.

The cut-off switches work and are ready to be attached.

What we didn’t do:

We haven’t installed the sonar sensors or the cut-off switch yet.

Where we are stuck:

 

Upcoming Week

Goals:

Instal and test sonar sensors.

Find material to place on the bottom of the shelf for attaching the sensors.

Attach cut-off switches.

Find a way to wire the sensors and switches, so that it doesn’t intrude on the shelf.

Hopefully we’ll have the RF remote, so we can test that.

Current Week

Individual Hours:

Shanto – 3 hours

Andrew – 3 hours

Jeff – 6 hours

Ibrahim – 3 hours

What we did:

We found a Keyfob RF remote which we can use to control the shelf. The receiver is programmed to make the pin go high when the corresponding button is pressed once, then switch to low when that button is pressed again.

We have sonar sensors that may work well for the safety feature to be mounted on the bottom of the shelf.

We began testing the relay and switch with the shelf.

What we didn’t do:

We don’t have a working remote for the shelf, but we plan to use the one we found online.

We didn’t mount the light sensors, because we’re considering the sonar sensors.

We couldn’t get the relay to work with the shelf.

Where we are stuck:

We need to re-wire the relay and determine why it wasn’t working with the shelf.

Upcoming Week

Goals:

Order rf remote and begin installing it to the relay.

Install sonar sensors.

Install cut-off switch.

Current Week

Individual Hours:

Shanto – 3+ hours

Jeff – 3+ hours

Ibrahim – 3+ hours

Andrew – 3+ hours

What we did:

We tested the IR sensors on the shelf.  They work, but they don’t detect over a large enough lateral range.  We’re trying out led sensors instead.

Tom gave us a relay which we can use to drive the motor instead of the Arduino.

We did some work on the rf remote.

What we didn’t do:

 

Where we are stuck:

 

Upcoming Week

Goals:

Mount the stop switches and light sensors on the shelf.

Test what code we have so far on the shelf.

Finish rf remote and drop code into an ATtiny.

Current Week

Individual Hours:

Team met for 2 hours on Tuesday, 10/1.

What we did:

We found some sensors.

We tested them using an Arduino and code we found on the internet. They work.

What we didn’t do:

We need to test the sensors with the shelf.

We need to build the switch that will replace the current switch.

Where we are stuck:


Upcoming Week

Goals:

Add sensor to shelf.

Build push button switch.

Have shelf and all its components ready for testing within the next couple of weeks

Current Week

Individual Hours:

Shanto – 3 hours, team meeting, meeting with Tom

Andrew – 3 hours, team meeting, meeting with Tom

Ibrahim – 2 hours, team meeting

What we did:

We looked at sensors available in the lab that could be used for our obstruction sensor. Our favorite so far is an analog IR distance sensor.

We met with Tom. He showed us a receiver and transmitter which could be used as a wireless rf switch. We used an Arduino to test out the devices. We also checked out the Arduino so that we could test out the devices further.

Tom also introduced us to ATtiny which could be useful for the switch.

What we didn’t do:

Currently we’re on task with our Gantt chart. However, we want to have the sensors and controls installed on the shelf and working by fall break. So, we need to pick up the pace so that we can have everything working in the next two weeks.

Our contract was ok’d by Dr. Skinner via email, but we still need to have him sign it.

Where we are stuck:

The IR sensors only allow for a small range of sensibility. Sense we want to protect the entire bottom of the shelf from obstruction, we’d need many sensors to detect any objects along the full width of the shelf, which would be too expensive.

Upcoming Week

Goals:

Build a switch that can communicate with an Arduino.

Continue working on obstruction sensors.

We want to have everything working by Fall Break.

All members met for 3 hours on Tuesday.

What we did:

We met with Dr. Skinner. He gave us input on our project contract. Afterward, we made revisions to the contract. Also, we revised our gantt chart to match our new contract.

What we didn’t do:

We still need to get Dr. Skinner’s approval of the contract.

Where we are stuck:

Need a suitable sensor.

Upcoming Week

Goals:

Order more analog IR distance sensors

  • model#: sharp 2d120xf78
  • qty: at least 4

Write arduino code for sensors.

Write arduino code for the switch.

What we did:

Went over the ideas provided by the CPRF residents.

From there, we came up with the basics of our semester project.

  • Wireless controller
  • Button that doesn’t have to be held down
  • Sensors for safety features

Typed up our contract and scheduled an appointment with Dr. Skinner and Tom McGuire.

What we didn’t do:

Forgot to revise the Gantt Chart.

We got in contact with Tara to set up a meeting with the CPRF residents (Shari, Jerri, and Sheridan). On Tuesday, we came up with questions to ask the residents. Jeff got a Bluetooth chip for the Arduino. On Monday, we met with the residents. They tested out the prototype and gave us feedback which will help us plan out our semester.

What we didn’t do:

We still need to edit our Gantt chart and develop a contract with Dr. Skinner.
