The purpose of this project was to troubleshoot the previously made solar robot charging station and find out why it no longer worked and make it waterproof. The previously designed station no longer worked once the teacher went to use it and it was not easily fixable. The team's objective therefore was to make the station easily fixable/re-creatable if needed as well as educational for the students.

After getting the station back in working order it was needed to be made waterproof as it will be subject to coastal weather conditions where it rains a lot. The station will be implemented at Zane Middle School in a teachers classroom and will recharge the classes robots and hopefully inspire the children in the classroom and spark their interest in renewable, clean energy.

Abstract

There should be an image near the top. The purpose of this project was to troubleshoot the previously made solar robot charging station and find out why it no longer worked. After getting the station back in working order it was needed to be made waterproof as it will be subject to coastal weather conditions where it rains a lot. The station will be implemented at Zane Middle School in a teachers classroom and will recharge the classes robots and hopefully inspire the children in the classroom and spark their interest in renewable, clean energy. This page will provide the details of the project and the final results.

Background

Team Wooden Lions was formed during Lonny Grafman's 2018 Spring Engr215 class to come up with a solution to fix a previously designed solar robot charging station. The station is used in a classroom at Zane Middle School to recharge their robots, reduce their carbon footprint, and to provide an educational and inspirational impact on the middle school children. Team Wooden Lions needed to troubleshoot the station to figure out what was wrong with it first and then get it back in working order. Once the station was working again it needed to be made waterproof as it is subject to coastal weather conditions. Outside what was required the team wanted to also try and improve the station where possible.

Problem statement and criteria

The solar-powered robot charging station no longer functioned that a previous engineering class made. The station needed to first be fixed so that it worked again and then needed to be made waterproof as it is subject to coastal weather conditions. Beyond that small improvements could be made as any second version does. Below is a list of criteria that our team came up with that we thought would improve the station and help meet the client's needs.

Criteria

Criteria Weight Constraints
Safety 10 Must be “safety approved” by multiple teachers at the school
Durability 9 Must be durable enough to not break while moving it and withstand middle school kids. Must be able to also withstand the climate conditions, most importantly the rain.
Mobility 8 Needs to move around a classroom easy enough by a teacher or students. Must be able to move with ease by a teacher in various terrains such as dirt, grass, concrete, etc.
Security 7 The robots are worth over $400 and so the school would benefit from some sort of a locking system while they are being charged
Capacity 6 Must charge at least 6 robot batteries, each 2200mAh
Cost 4 $325 max
Versatility 3 Many attachments can be added to the station to make it more versatile. But in the end, all that must be made is at least the waterproof solar-powered robot charging station that was requested by the client.
Aesthetics 2

Must look at least as professional as the previous project

Description of final project

Photos and descriptions. Use gallery.

Include a how to use and maintain section. See the how to template below. The solar powered robot charging station consists of the basics needed to run solar. 4 Solar panels are mounted to the top that is connected to the charge controller. The charge controller is used to protect the electronics by regulating the power and keeping it from overheating and provides the level of charge that the battery is at. The charge controller is then wired to the battery and the chargers. The battery is a 12v 35Ah deep cycle solar battery and powers the chargers. All the electronics are routed together through the bus bar which then goes through voltage regulator to bring the voltage from the 12v battery down to a usable 5v for the usb and robot chargers. Everything is housed in a metal tv stand that is waterproofed by epoxy in the gaps. A door and lock was installed on the front to protect all the electronics from theft and water damage.

Prototyping

Use a gallery of prototyping photos and lessons learned.

How to build

Use Template:How_to


Maintenance

The previous station was poorly maintained and is one of the reasons why it failed so quickly so this section will include how to keep the station working for years to come.

Schedule

This is when to maintain what.

Weekly
  • Charge the battery fully in sun once a week
  • If there is not enough sun plug the battery into the provided trickle charger

-(Input the different color codes of trickle charger)


Monthly
  • Clean the solar panels with just water if possible and if that doesn't work then just soap and water.


Every 4-8 years
  • Replace battery depending on how well maintained every 4-8 years. If the battery can no longer hold a charge it is time to replace it. Take the battery to an auto parts store to recycle and they will refund a core fee of about $10-15.
  • If the paint is faded spray paint a new layer on

Instructions

This is how to maintain. The step by step how to template {{How to}} is most likely best for this part.

For the picture add one of hooking up the trickle charger. Description: Hook up positive clamp (red) of trickle charger first to the positive terminal on the battery. Then hook up the negative clamp (black) to the negative terminal on battery. (Ask lonny if they can just hook up directly or if panels need to be turned off etc.) (Ask lonny if we need to add how to clean the solar panels) If LED remote battery runs out, replace with (insert battery type) If the charge controller needs to be unplugged, Remove consumer wires, negative and then positive. Then the solar panels in same wire order, and lastly the battery in same wire order. (Add photos of the individual sections)

How to Do Something

Troubleshooting

This is only how to troubleshoot basic operation. For complex issues, the solution might just say contact ________. It should be a table in this format:

Problem Suggestion
Example issue Example solution or suggestion
Does not turn on Make sure it is plugged in
Another issue Et cetera

Discussion and next steps

Suggestions for future changes

This is where to lay out suggestions for how to make the project function better in the future.
