Standard football league platform in action.

This is the second of our daily dings from the Robocup2024 in the Netherlands Eindhoven. If you miss the first digest that gives some Robocup background, you can find it here.

The competitions continued in all leagues today and the participants competed for a place in the Sunday final.

Robocup@Work League focuses on work -related robots, uses ideas and concepts from other Robocup to solve open research challenges in industrial and service robotics.

I arrived in the arena in time to capture an advanced navigation test. The robots must navigate, pick up and place objects on various workstations auto. In this advanced test, a tape warranty is added to the arena floor that robots should avoid traveling. There is also a complicated element of location where the teams have to insert an object that are collected in the slot – get the orientation or location of the object a little badly and does not fall into the slot.

Eight teams participate this year. Member of the Assad Norouzi Executive Committee said there were plans to introduce a Sub-theoal, which provides WELD entry point for new teams or juniors to get the right league.

I dreamed with Harrison Burns, Mitchell Torok and Jasper Arnold of Team Mirobot. It is based at the University of New South Wales and is waiting for the first time Robocup.

In fact, the team only started six months ago, so the final preparations were a bit stressful. However, the experience was great fun and the competition has gone through. Like most teams, they had to make many improvements because the competition progressed, which led to late night.

One of the remarkable features of the team robot is a custom, infigory grip mechanism at the end of the arm. The team notes that “has good flexible jaws, so when it grabs round objects, it actually connects the object. Because it used a linear movement, compared to many other rotating jaws, it has a lot of boutiaBibility to pick up objects ”.

Here are several shots of this task, representing a team bi-t-bots and Team Singapore.

In the middle -size football league (MSL), teams of five fully autonomous robots with regular FIFA ball size play. Teams can freely design their own hardware, but all sensors must be on board and for robots the maximum size and weight limit is 40 kg. Research focuses on mechatronics, control and cooperation with more agents at the level of plan and perception. This year, nine teams compete.

I talked to António Ribeiro, a member of the Technical Commission and part of the Lar@MSL team from the University of Minho in Portugal. The team began in 1998, but António and most of his colleagues in the current team were only involved in the sale of MSL September 2022. Robots evolved as the competition advanced, and further improvements are underway. So far, refinaries include communication, detection system and control system. They are satisfied with improvises from the previous robocup. “We had a lot of hardware last year, but this year the hardware seems quite stable.” We have also changed our coding architecture and now it is much easier for us to develop the code, because we can all work at the same time on different modules ”.

António quoted versatility and cost -effective solutions as the strengths of the team. “The robot is very cheap compared to other teams. We use many old chassis and our solutions always increase the lowest costs. Some teams have more thousand dollar robots, but for the test our vision system is around $ 70-80. It works ready – we have to improve the way we can do it, but it seems stable ”.

Team Lar@msl

The aim of Robocup@Home League is to develop services and assive robots with high resivance for future personal domestic applications. A set of reference tests is used to evaluate the abilities and performance of robots in a realistic non -standardized environment. These tests include assistance in preparing breakfast, cleaning table and food storage.

I arrived in time to watch the challenge “Stickler for the Rules” where robots must go through different rooms and make sure the people inside (“guests” at the party) hold the rules of the oven: 1) , the robot must alert them and ask them to follow it to another room), 2) everyone must have a drink in their hand – if not, direct them to the shelf with drinks, 3) not shoes that are worn in the house, 4) to The floor should not be any garbage.

After Tiago watched the team from the robot Lar@home, he told me something about the robot. “The aim is to develop a robot capable of more general tasks in domestic and medical environments.” With the exception of the robotic arm, all the hardware was built by a team. The robot has two RGBD cameras, two Lidara, a magazine (where the robot can store the items it needs to carry), and two emergency stop buttons that deactivate all moving parts. The oMnidivije wheels allow the robot to move in any direction at any time. The wheels have independent domestic systems that will ensure that everyone can always be on the ground, even though there are bumps and cables on the upcoming floor. There is a tablet that works as a visual interface, and microphone and speakers that allow communication between people and robot, which is done by speaking and listening.

Tiago told me that the team had spoken to many medical practices to find out a problem with the hands in front of the elderly, and this inspired one of their robotic features. “They said two main sources of injuries have been since people are trying to sit or get up, and when they try to pick up something from the floor.” We have developed a torso that can choose objects from the floor one meter from the robot ”.
