ICRA MMC Day 01

This morning at 7:30 we arrived at the Sands Expo and Convention Centre next to the famous Marina Bay Sands Hotel. We were first at the competition place and the Robomasters team was still building the arena place. But we could enter and set up the robot.

Then other teams arrived and we have to say Wow!, we are impressed. Two teams directly tested and were able to stack 10 cubes on each other. Thats a height of 2.00m with a robot of 0.8m height. Most of the teams follow a similar approach as we do for the gripping procedure. It looks like they do not build a map and navigate but instead rely on odometry and some are navigating blind but very exact. It was very impressive to see one team that in their second test slot stacked all of the cubes. That means the structure was 3.2m in the end. Wow, just wow. Very amazing to see a small robot to build this.

A Chinese team with their well engineered robot achieved to stack 3.2m. Wow!

The other teams have more focused on the mechanical design and two of the teams have astonishing mechanical designed robots that take two cubes at once in the starting area and then transport them to the working area and stack them afterwards. Before stacking they align the cubes they want to stack on top with a kind of press that brings them at the exact location where the other cubes will be stacked on. This looks very smooth and is in fact a good idea.

We will have a really hard time here but are still focusing on solving the task as best as possible. We have some major design issues like that we can not lift two cubes on top of another set of two cubes. We designed the robot this way because our version of the Rulebook stated that only one cube could be carried to the working area. Seems like the Chinese version of the Rulebook was more up to date. We are still enjoying the competition and met some nice people from other RoboCup teams and companies.

The other teams where interested in Maggie, after they have seen our first round

Tomorrow the competition starts. Let’s see :) Currently we are that close to be kicked out of the Conference location because of the late time. We are proud to be able to stack 7 cubes. That was our last test trial. Far away from 3.2m but the solution is looking elegant and most probably the most generic solution at this place.
