Revision as of 20:18, 3 March 2017
Ki is a senior-designed 3lber, introduced as a project to test out experimental 3lber ideas. It was designed and built during the Summer and early Fall of 2016 for Sparkfun, a competition in Colorado.
It was then redesigned for Motorama 2017.
Its central concept is an asymmetrical horizontal bar spinner. The original design's horizontal bar looked like a key, hence the name. Other features include .25" UHMW armor in Ki and .5" UHMW armor on Kii.

Competitions
Sparkfun 2016
Results: 1-2
Bracket type: double elimination
- Loss vs Margin of Safety
- First fight against Margin of Safety. Great odds.
- At first, Ki and Margin are exchanging weapon hits. This pattern soon ends as Margin rips off all 3 armor pieces. Ki loses by tapout.
- Win vs Kamikaze
- Kamikaze is a full-body bar spinner with an ABS frame and massive weapon.
- Kamikaze and Ki exchange blows for around 30 seconds, after which Kamikaze tears Ki's back armor off. It then ricochets, breaking its own ABS chassis and KO'ing itself.
- Loss vs Just a Wedge
- Just a Wedge is, as its name suggests is just a wedge.
- It was a wedge fight for most of it. Just a Wedge got its wedge stuck under a saw field hazard. Ki then bumped it free after a short time. Ki loses by judges' decision.
Motorama 2017
Results: 0-2
Bracket type: double elimination
- Loss vs Meili
- Meili is another horizontal bar spinner. Oddly, its bar is at the exact height of Kii's belt.
- At first, Kii and Meili are exchanging blows. Meili then knocked Kii's back armor around in such a way to lift Kii's drive wheel off the ground. Then Meili's bar cut Kii's belt, at which point Kii lost by tap-out.
- Loss vs Deathcap
- Deathcap is an drum spinner with an elevated drum.
- Early on, Deathcap and Kii hit, resulting in Kii's right wheel being knocked off. Kii held Deathcap off for the full 3 minutes, and then lost by judges' decision.

Problems
- Ki's weapon shaft was bolted on by only 4 4-40 screws.
- Its weapon shaft had two pieces that screwed together by threaded rod, resulting in odd interfaces with the weapon support system.
- Ki's top and bottom plate used 3/16" that had pockets to be milled down to 1/16". Not a good idea.
- Ki's armor pieces were screwed into the 3/16". 3/16" is too small to support 4-40s, and screws in general.
- Body is unecessarily large.
Good aspects
- The central concept of the bar support pieces was good.
- The weapon, when its support screws weren't shearing, performed well.
Changes/Improvements
- Reduce body size
- Use a screw for the shaft
- Make bar counterweight smaller
- Improve armor mounting

Problems
- The wheels were unarmored and came off frequently.
- There were still issues with enemy bots tearing armor off.
- Weapon motor was mounted to 1/16" Al. It bent, resulting in the belt coming off relatively frequently.
- The belt was an easy target.
Good aspects
- The weapon was effective.
- The wheels worked well, when they weren't torn off.
- It was easy to access electronics with the weapon support layer made of 3/16" Al with 1/16" Al top and bottom plates.
