Building for the Plastic Antweight division begins with 3d printing your custom design!
Using your custom printed parts with some OEM electronics, like motors ESCs, servos, and switches, this is where ideas come to life
Oregon State Combat Robotics members have access to 3d printers and club supplies, including OEM parts. Depending on your custom design, your part requirements will vary.
After designing your ultimate combat robot, the next step is printing the parts. In order to do this, a program like Ultimaker's Cura or PrusaSlicer slices the design into layers, and routes, for the 3d printer to follow.
Within the slicer are several settings available to maximize the strength to weight of the individual part. The number of walls, density of infill, and infill shape are the most common. The more walls, higher percentage infill density, and more complex infill shape, all increase both strength and weight.
Combat robots typically fall into one of three categories that help outline their parts requirements:
In an effort to provide the best experience, all club sponsored bots are all powered and controlled by the same 3s LiPo 450 mAh battery packs, dual-speed controllers, AHFDS radio protocol. Other electronics setups are noted here:
|Bot Type||Drive Motors||Weapon Motor||Weapon Controller|
|Wedge / Pusher / Rammer||16mm Silver Spark||none||none|
|Spinner (horizontal or vertical)||n20 gearmotor 600 rpm||2830 brushless motor||30 amp BESC|
|Lifter / Grabber||n20 gearmotor 600 rpm||20 kg digital servo||6v UBEC|
