Autonomous Sumobots

Using prior knowledge of gear ratios and drivebases, students will design, build and code their robots to compete in an Autonomous Sumobot Competition.

*Materials and Project Guidelines same as the Driving Sumobot Competition

Preparation and Materials

Teacher will group students in groups of 2.

Sumo ring (can be a circular board) or a Square mat about 4 feet across.

Project Guidelines

Robot Rules

Robots must fit within a 12" by 12" square at all times throughout the match
No height limit
Maximum of 4 motors
No weapons of any kind
No extending appendages (claws, lifts, hammers, sweepers)
No flying components or projectiles
A robot cannot deform or destroy the ring

Game Rules

Two robots start behind the line facing each other
One driver for each team per match
At the start of the match, drivers have 30 seconds to push the other robot off the field
A robot is deemed "out" and treated as a loss if
- Pushed completely off the ring and on the floor
- Drives itself out of the ring and on the floor
- Flipped on its side and unable to right itself back within 3 seconds
- Unable to move for more than 3 seconds
The match is deemed a tie if at the end of the match, both robots are still operating and in the ring
Teams will be ranked based on total number of points scored
Intentional attempts to destroy another team's robot will result in a 0 for the match

Autonomous Rules

Must include at least two sensors in your robot and code
Program must be at least 30 seconds in length (length of a match)

Homework

Sketch out three different designs for your sumobot in your notebook
Create three different programs for your robot using different combinations of sensors. Create flowcharts for each code.

Classwork: Project Work Time

Students in groups will work on designing, building, coding, testing, and improving their Sumobot.

Assessment: Autonomous Sumobot Competition

Have all groups present their informal presentations about their Sumobot
Randomize match pairings
Begin the matches and teacher may decide how many matches to run
- Recommend to run at least 3 matches per team so each team gets an opportunity to get a possible 5 ranking points.
At the end, tally up the ranking points based on W, T, L

Rubric

Homework: Make it Better

Have students answer the following questions in their notebook:

What went well in the competition?
What didn't go well?
What would you improve to the design and build of your robot if you had more time?
What would you improve on the programming and sensor integration of your robot if you had more time?

Optional Extension

Have students compete in a 2nd round of competition after making improvements to their robots.
