This is a brainless robot challenge, those are the only ones I can build so far.
Objective: build a robot (with no programmable brain) that can seek and find an object and then push it out of the platform where both sit in the shortest time possible.
The platform is a square of 50cm
The object must be 3 times heavier than the robot
The object must be placed 10cm away from the platform edges
The robot should not leave the platform
To start the robot should be place "looking" completely opposite to the object, in other words not looking at it
The robot should NOT have a programmable brain (picaxe, arduino, BASIC, etc)
The robot should be autonomous
No limit in amount of sensors
The price of constructing the robot should not exceed 20 USD or valid currency exchange
If the robot is build completely of recycled parts the cost will be assumed as 0.5 USD
Each robot will be qualified by the formula (Time / cost) * 100
The best robot will receive a "Certificated of Awesomenticity"
Regards and have fun
