Varsiti was designed out of a deep and uncompromising passion for sheer weapon size. As a result, the frame was rather thin to save on weight so more of it could go towards the metal of the beater bar, until ultimately the weapon accounted for over a third of the bot's total weight. Although the invertible drive system functioned and was well contained in HDPE sheeting, the bot didn't achieve the traction it needed in the drive wheels because the center of mass was too far forward. Handling ended up being the bot's fatal flaw, but nobody could deny that the weapon was very, very large.

Competitions

2lb Competition 2021

• Results:
  • Single Elimination:
    • [L vs Largetoni]
      • As a result of poor traction in the drive wheels, Varsiti was unable to approach Largetoni to deliver a blow when opportunities emerged early in the round. After a couple glancing blows from each, Largetoni flipped Varsiti, which caused the thin bottom plate to break, resulting in the bot's weapon pulley unseating from a change in the frame's dimensions.

OTHER:

Problems

• Weapon was extremely unbalanced, couldn't spin up to full speed without major bad vibes
• Center of Gravity was too far forward, so there was little to no traction on the drive wheels
• Loose mounting of electronics (didn't cause any major issues with handling and had little risk of wires being damaged, though)

Good aspects

• Looks Good (we think)
• Big Boy Weapon™
• Weapon Spins (extremely unbalanced though)
• Easy access and good protection of the wheels with HDPE side plates
• Good electronics isolation (wires kept away from moving parts using dividers
• Ability to easily hot swap weapons and weapon support plates (the part at the front with the nylon transfer bearings and the V cutout)
• Lots of space for electronics and wiring
• REALLY Big Boy Weapon™

Changes/Improvements

• More ground clearance
• Move Center of Gravity to center for better steering (New beefed up weapon moved CG really far forward, away from drive wheels)
• Better mounting of components
• Beef up chassis (thicker walls, more cross bracing, thicker side HDPE protection)
