The Design Process:
The Engineering Design Process is a systematic approach to solving real life problems. Although many resources deviate the break up of how the design process should be approached, all have the common ingredients, Define the Problem, Generate Concepts, Develop a Solution, Construct and Test Prototype, Evaluate Solution, Present Solution.
As a certified Project Lead The Way School, We are taught from our freshmen year this approach to generate solutions in an efficient, yet productive manner. Below is the Design Process that we used.
Below are some pictures of us following the Design Process!!
1. Define the Problem
Design and build a robot to perform farming operations. A robot can score points the following ways:
1. Plant corn seeds
2. Harvest and deliver ripe corn
3. Harvest and deliver hydroponic tomatoes
4. Harvest and deliver hydroponic lettuce
5. Corral and secure loose Pigs and feed them
6. Turn on the water valve
2. Generate Concepts
Since we have been involved in BEST Robotics since 2014, our team has evolved from a Rookie Team to a Veteran Team. We have researched many Chassis and have tried numerous ones throughout the years. This year, we have decided to stay with the rectangular design until we are almost finalized with the robot build, then make any last minute modifications from there. By doing so, we will not have any waste of material.
For the arm which will be used to pick the tomatoes lettuce and corn , we brainstormed many possibilities on how we can accomplish the task at hand. We thought about utilizing our pvc pipes because they are modular and cheap to replace if needed to. We also looked at the linear slide hardware which was generously donated to us by Igus. As a group consensus, we chose the linear slide as our winner due to it being able to extend with ease and its construction is made of easy to cut and drill aluminum.
In order to be able to physically grab the corn, lettuce and tomatoes we decided to use an idea that we thought and created last year. it was a laser cut wood claw that was powered by our Futaba servos and rubber bands for tension. Since we are allowed to use a 3D-Printer with given constraints, we think that we can build on last years design and make huge improvements.
In order to complete the tasks about transporting the vegetables as well as move the pigs to the pig pen, we decided to postpone our design brainstorms until mall day. That way we can see what we have in terms of the chassis and arm in order to determine best places to incorporate them onto our chassis.
3. Develop a Solution
Here are a few pictures of us developing our solutions. we used Autodesk Inventor since this is what we use in our PLTW engineering classes.
In the pictures, we have Gabriel modeling the gears that are going to be used for the claw that is going to be used for the vegetables.
Saul is working on making an adapter piece to that we may attach the Futaba servo onto the linear slide which is going to be used for the arm.
Frankie is working on the preparations for the 3D printing. In the picture he is converting the Autodesk model file (.ipt) into the universal file extension (.stl). All 3D-printers utilize the .stl format because it generates the path which is needed for the extruder to follow.
4. Construct and Test Prototype
Please take a look at what we did to construct and test our prototypes! with a week to go, we have few modifications on the arm and claw that are needed. We are just waiting to test them out during Mall Day. If you have any questions, you can always tweet us at @socorrohsstem 🙂
5. Evaluate Solution
During our testing of our prototypes, the claw has been through many modifications on the design. Since we are limited to the 2″ x 4″ constraints, we needed to modify our design to meet the needs. The hardest part that we are struggling with is to retrofit our design to the Futaba servo horn axle. We are still in the process on tweaking our design.
The shaft collars that we created using a metal hole drill bit was not the best. after the cut, the 2″ hole came out a little bit crooked. This is effecting our laser cut wheels to wobble as it is rolling on the floor. We are going to look into the option of using our CNC mill to cut into the aluminum which will result in better precision in our design.
6. Present Solution
Please come back on Game Day (October 22, 2016) to see our Final Solution!
