Today I got the question: Is a robot with a remote control that takes a step with each press of the remote (walks) the same as a remote controlled car? Rule 9 in robotics for the Kansas State Fair states: “Remote controlled robots are allowed under certain conditions provided that the robot is not drivable. Remote controlled cars, boats, planes and/or action figures, etc. are not allowed.”
Here is my interpretation of Rule 9 for the Kansas 4-H SpaceTech Robotics as published for 2019 Kansas State Fair.
The big question on this is what are the “series” of actions that occur each time you press the button?
If you press the button and the logic for the button press, for example, is spin motor for 5 seconds or 200 degrees or until you let go of the button and that’s all that happens. Then it’s the same logic as a remote controlled car. You press the button and it moves forward and that is the only thing in the logic “series” that happens.
Now, if the robot has more sets of logic in the series, like spin motor 1 for 200 degrees, spin motor 3 for 90 degrees, leave motors 2 and 4 stationary, and then motors 2 and 4 repeat the 200 and 90 degree spins while motors 1 and 3 remain stationary. That’s a logic series of tasks, and that’s really the dividing line. If when you press the button more than one thing is happening for that button click (preferably with some form of condition like an “if” or a “while” statement) then there is a clear difference between remote control cars. In other words a whole series of things has to happen correctly for it to move forward, not just spinning a motor till you let go of the button.
For example if you built a remote controlled robot that did a figure 8 when you hit a button, that is a series of actions: turn left, keep left, keep left, turn right, keep straight, turn right, keep right, keep right, turn left, keep straight, repeat. The operator with the remote doesn’t have to know all the steps to perform a figure 8, the robot already knows them and the operator just has to know to push the button.
Example of a car’s, boat, action figures logic:
Example of more sophisticated logic or a “series” of events that goes beyond a typical “remote control car” setup:
This is why the rules ask for the copies of the code used for the robot. That way the judges can see the logic of how a robot functions, is it just a single thing that happens with the push of a button or is there more happening, something that shows the robot completing a task? (In this example 4 motors being logically orchestrated in a specific sequence to “walk” in a given manner.)
This is my interpretation of: Is a robot with a remote control that walks the same as a remote controlled car? Other judges and superintendents may interpret this rule differently and that is their desecration to do so.
