Team 263, Sachem Robotics’ Prototype and deployment.

The new bot has two motors, the second is attached to the smaller wheel. Since it has a 2:1 gear ratio, the smaller wheel goes twice the speed.

The last trial runs were:

2.9 – 3.1 range
  • There are no magnets other then the ones inside the motors 😀
  • There is ghetto wiring currently installed on the bot and there has not been any programming set on the controller yet.
  • When the power is manually cut at the top of the pole, it slowly goes back down the pole.
  • It is very picky of it’s center of gravity. The bot will fall off the pole if a wheel is too far in.
  • The wheels were shaved down to the shape of the pole, as well as adding grip to it.
Update: (Febuary)
Our minibot and deployment have changed dramatically while maintaining relatively the same speed. The following video is our fastest, yet unstable model.

See the video of our final version in action, with an Uber tube tied behind our back, for the win.
