Continued building!

I don't have a lot of time to spend on writing this entry so I will keep it short and to the point. I have completed all the transfer systems on one side of the robot (Upper intake, Bottom intake and upper transfer system.) I have also finished the uptake injector system and have mounted and tested the uptake (but have not yet mounted the powertrain.) I have been printing multicolor signs for the robot which required me to learn how to edit G-Codes so I could print the signs with a single-color printer!
Our third order has arrived containing the remaining parts that will be crucial to the remaining parts of the build. Unfortunately, we are missing 2 belts and 2 gears because we forgot that we need them on the robot. Thankfully those parts do not hinder the progression of the testing.

“Finished” CAD and continued printing and assembly!

I finished grinding all of the screws that we will need for the chassis (12 in total) and continued to 3D print parts for the robot like side panels, bumpers and spacers. Some of the parts our team ordered are coming in so we are able to slowly build with those parts but are main order with all the parts has been delayed so that is greatly slowing us down. We have mounted the bumpers on the robot and so far all the parts seem to fit together well. I have gone through about 1.25 kg of filiment and probably use up another 1.5 to 2.5 kg! Last week we slapped on a battery and control hub and did a test run and everything worked perfectly so that is great that we know at least something will work! ;) Next step is to finish the CAD (which should be close done but probably isn’t as in robotics it takes a lot of trail and error to figure things out) and keep printing!

Chassis assembly!

I finished all the major parts of the robot in CAD and have been working on the assembly of the chassis, which includes 3D printing parts and grinding down bolts so that they don’t touch the belts. I have also started to put together the bottom intake but have run into a problem with the intake wheels being to big and touching the ground so I will have to replace those with smaller ones but that is ok. The Chassis assembly has gone pretty smooth after I figured out the order in which to put it together so that’s great. The next step is completing the CAD and waiting for the parts to arrive as I start 3D printing the parts.

completed the upper artifact transfer system in CAD!

Since this is my first journal, and I have already started this project I will explain what is happening now and what I need to get done in the future!

As of today, I am about eighty percent complete with the CAD and ninety percent done with the drivetrain and chassis of the robot! So far, the robot contains 6 different stages of transfer for the artifacts of which 5 are designed and 1 is already partially built. First, we have the Initial intake, then the Upper transfer system, Uptake injector system, Uptake transfer system, Shooter and Turret! So, what's next? Well, I have to design the Hood, mounting brackets for battery and hubs, side panels for aesthetics and robot signs. Since our team will be ordering the remaining parts tomorrow the rest of the CAD should be done by the time the parts get here and then we can start assembling, printing, coding and wiring. (The fun part!)

The fun stuff! \/

This is a screenshot of the entire transfer system designed so far and the path the artifact takes before it gets shot out.

This is a screenshot of just the Initial Intake (Left) the upper transfer system (Middle) and the Uptake injector system (Upper Left) and the path that the artifact takes as well as direction of rotation of the boot wheels.

Screenshot of just the Upper transfer system which is the most recent part of the design!
