WRO 2018 – Challenges

WRO 2018


Regular Category

Participants from 7 – 12 years in the year of the competition.


Nearly 800 million people worldwide suffer from hunger. Still, about a third of the world’s food production is never eaten. It goes to waste.
A country like Thailand produces many kinds of food products. Unfortunately, much of the food is sent to landfills, or is discarded, or is left unharvested on farms because of its appearance and age. Thailand farms, businesses, and consumers spend a large portion of their resources every year, growing, processing, transporting, and disposing food that is never eaten.
This year, the mission is to make a robot that can help reduce food waste. The task of the robot is to sort food products according to their looks and expiration dates and transport the sorted food to places that can make use of the food instead wasting it; i.e. dumping the non-sellable food to a landfill.

Participants of 13 – 15 years in the year of competition.

With a growing population in the world, more and more food needs to be produced every year.
One way to get an increased food production is to use technologies like robots, drones, and satellites to improve the usage of arable land. Satellites and drones can provide accurate data on the soil quality of the different areas of the arable land. This data can be used by robots (self-driving tractors) to plant different seedlings on the land depending on the soil quality. In this way, the seedlings are adapted to the growing environment, which will improve the growth of the seedlings.
The mission of the robot is to gather data on the soil quality of the fields of different farms and use this data to plant different seedlings depending on the soil quality.

Participants from 16 – 19 years in the year of competition.


One way to increase the amount of food available worldwide for the consumers is to improve the way food is distributed from the producers to the costumers. This means that the primary goal of food distribution is to make sure that the consumers get the kinds of foods they demand from the producers. The secondary goal is to make sure as little food as possible is wasted during transportation.
The Senior Challenge is to make a robot that can bring different kinds of food to the right destinations by appropriate ships and a robot that can equip the ships with temperature controllers that keep the different kinds of perishable food on board the ships in the desired temperature range during transportation.

Advanced Robotics Challenge

Participants 17 – 25 years in the year of competition.


The challenge is to make a robot that can score as many points as possible in a robot version of the Tetris® game called Tetrastack. The robot will locate, identify, and stack interlocking colored shapes called tetracubes within the Stacking Form – a rectangular upright box.

WeDo Open Category (Age up to 10 years)


The WeDo Open Challenge is for each team to use WeDo 1.0/2.0 elements to construct automated machinery and robots the team can use to illustrate, explain and demonstrate how automated machinery and robots can help humans grow more food. The constructed automated machinery and robots must be placed in an exhibition booth and the team must be ready to demonstrate it for visitors and judges.

WeDo Regular Category (Age up to 10 years)


The WeDo Regular Challenge is for each team to build and program a WeDo 2.0 robot that the team can use to complete a series of tasks within a Game Table. The tasks are to collect and sort four pieces of fruit placed on a Game Mat and transport the fruits to different locations depending on their appearance. Each team will use their robot to perform the tasks within 2 minutes.

WRO Football

Participants from 10 – 19 years in the year of competition.


WRO Football aims, where possible, to reflect the game of human soccer. Teams of two on two autonomous robots chase an infra-red transmitting ball around a WRO size table top field with the aim to kick more goals than the opposition.

Open Category

Same age of the Elementary, Junior and Senior categories.

The mission this year is to build a robot that supports the way we grow, share and consume food. Your project should focus around at least one of the following aspects of the Goal 2 of sustainable development:

  • Promote sustainable agriculture:
  • Improve nutrition
  • Achieve food security
  • End hunger
