2019 Deep Space
Pre-Rookie Build: The Lakerbots are building an "Off Season" Robot to compete in the final events of the 2019 season Deep Space.
This Build Blog will detail the teams efforts to compete in two preseason events: The Governors Cup and the Battle Of the Bay.
KOP Chassis:
Our Lakesbots team chose to build the pre-made chassis because there was not enough time to build our own with the time that was given to us. We chose to go with a square configuration out of a wide, norrow configuration. The wide is better for turning, but has less back and front stability. The narrow has less left and right stability.
The chassis is "tank drive" with two CIM motors on each side, the over all gear natio is 10.71:1. This results in a top speed of 10ft/sec.
Electrical Panel:
Process
In order to have a neat electrical panel, our team first laid out the panel on Onshape.
We then used the CNC machine to drill the holes and make the cutouts for the uprights that will be used in the hatch collector. Finally, we screwed the various parts of the electronics board to their respective locations. In the picture on the right, everything is attached, minus the pneumatics system and a couple of the Talon SRXs.
Electrical Connections
We used Anderson Pole 45 connectors for in between the motor and the Talon SRXs, ferrule crimps for connections between the PDP and the VRM, and some Wago barrel locks for the CAN bus.
Governors Cup: The team competed in it first competition and achieved their goal of being on the field for all of their matches. There were several electrical issues including a loose POE injector wire and a faulty signal from one of our controllers.
The team was honored to receive the “Winnipesaukee Judges Award” for its work to create a cleanly wired electronics panel using a CAD model and a CNC router, as explained to judges by the students. The Governors Cup is sponsored by the Eversource, The University System of New Hampshire, Governor Sununu and others and was attended by NH Commissioner of Education Frank EdleBloom.
Hatch Mechanism Super structure:
Custom Gussets: We designed and used CAM to make these custom gussets, they are made out of 1/4 in poly carbonate. These will be used to hold the uprights that will connect to the 45 degree supports to the hatch mechanism.
We used three machine strategies-
Adapted- this is used to cut out the insets for rivet heads.
Bore- the boring tool is used to put the rivet into the frame.
Contour- The contour tool is to cut out the shape of the gusset.
This is the G-Code from one of the custom gussets from above. After doing the CAMing, we post processed and then uploaded the file onto our CNC machine controller in the form of this G-Code, which takes the form of a bunch of X, Y, and Z coordinates that instruct the CNC where to go.
Cargo Mechanism
In the picture above are the blueprints for the mount hatch mechanism. We have already drilled out holes for the pneumatics tube.
Collecting/Scoring
The following is a video of what collecting and scoring a hatch looks like with our current mechanism.
