Design Summary

Skinn0 was named without the "i" as Skinni was intended to have shufflers so Skinn0 represents a negative iteration. It was pretty much designed and built in a week specifically for the December In House Competition 2023 hosted by Ryan and it was due to this short timeline that a wheeled version was created. The chassis consists of a TPU clamshell with an aluminum top and bottom plate. The shell is mostly printed TPU with an aluminum top plate for contact with the wheel and AR teeth.

Problems

• Weapon
  • Tooth mounts need more material
  • 1/8 in aluminum top plate prone to bending
  • Rubber wheel wore down relatively quickly, could have been due to the sandblasted top plate
  • Would lose contact with wheel, need supporting roller on other side
  • A little unbalanced, making drive hard
• Chassis
  • The wood screws were convenient at the time but opening up the chassis was kind of annoying due to how long the screws were
  • The motor mounts would heat up enough to melt through the TPU holding it in
• Drive
  • 2 Wheel drive centered on the middle of the robot is very wobbly and hard to control
  • Lack of traction exacerbated the unbalanced weapon problem and the chassis would constantly rotate in use

Not Problems

• Weapon
  • Spinup was surprisingly good considering the relatively small motor
  • Tooth design was nice and sharp
• Chassis
  • Clamshell design was very effective considering the little manufacturing effort and parts required
