Project Echo
building towards the first open source humanoid in Delft
We are exploring the added value that humanoid robots could bring to search and rescue operations in damaged and partially collapsed buildings.
We test this by developing an open-source humanoid designed to meet the demands of these disaster environments and putting it through realistic rescue scenarios in the RoboCup Rescue Competition. Our aim is to demonstrate that a humanoid can operate in these environments and identify the situations in which its morphology provides added value.
Status
Context
What makes us different?
the development of an open-source humanoid specifically for challenging search and rescue environments.
Gap in the research
Humanoids capable of operating in difficult real-world conditions are typically closed platforms, while open-source humanoids are rarely designed for damaged and partially collapsed buildings.
The Solution
We aim to bridge this gap with a platform that is both physically capable and fully open source. By teleoperating the robot through realistic rescue trials, we also capture a multimodal dataset of human demonstrations and robot–environment interaction, which we will open source to support the development of autonomous rescue behaviours.


Timeline
The origin
Dec
2025
A project originating from RoboArm 2025, that inspired Project Echo. A robot arm utilizing computer vision that can emulate the human arm using a simple laptop camera built by Wolf Lenssens.
The first pitch
Feb
2026
Pitching the new project at the project evening: a team building two 5 DoF robot arms mounted on a stand based on the previous design from RoboArm. This is also official start of what we now call project Echo. Here Bertjan joined as the first member
Team Expansion
Mar
2026
Two new members, becoming the new hand divison. A new vision was added, catching and trowing a volleybal. Two subteam hands and arms.
Industry Collaboration
May
2026
Our first official collaboration with Daimon robotics to implement their products on our arms. Examples are vision based tactile sensors. Also the first talk Ambionic to build a demonstrator arm with a new robotic hand.
Here we started the idea of building an open source humanoid for research and companies.
Winning regional Robotics Awards
Jun
2026
we have won the Student Award in the regional round of the National Robotics Awards 2026 for Noord-Holland, Zuid-Holland and Utrecht.
This means we were able to compete in the national final at FuturePulse 2026 in Eindhoven this September.
New direction of the team
Sep
2026
The team has a new mission: exploring the added value that humanoid robots could bring to search and rescue operations in damaged and partially collapsed buildings. Our core hypothesis is that human morphology can offer an advantage in environments that are fundamentally designed around the human body, with stairs, doors, narrow passages and objects that must be climbed over or manipulated.
We test this by developing an open-source humanoid designed to meet the demands of these disaster environments and putting it through realistic rescue scenarios in the RoboCup Rescue Competition. Our aim is to demonstrate that a humanoid can operate in these environments and identify the situations in which its morphology provides added value.

New hand and arm design
Jan
2027
By the end of Q2, we aim to complete he first second-generation arm and hand prototypes with the new cubemars actuators. The hand milestone will focus on integrating linear actuation for the four fingers, while the thumb may remain a separate mechanism at this stage.
ECHO II a mounted humanoid upper body
Jun
2027
By the end of Q4, we will use the results from these first prototypes to complete a second design iteration and replicate the validated limbs. This should result in a complete upper-body prototype.
Integrating with the Leg team to become ECHO III
Jun
2028
ECHO III will be our full humanoid with the aim that it can walk on uneven terrain
RoboCup Rescue
Apr
2029
Our goal is to participate in the RoboCup Rescue Competition as the first humanoid robot to take on its challenges. The focus is not on winning, but on completing the challenges and learning where humanoid
