Help with my summer project


My name is Anika and I need help with my summer project. I built a bot that will help us clean kitchen counter.

It has two problems

  1. The gyro sensor is not accurate even with resets. That means the bot make turns that are not perfect 90 degrees
  2. The ultrasonic sensor gets confused with distance when it goes over a liquid as you can see in the video. The real world testing part at the end.

How can we fix those two issues?

Thank You
