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

g and basic dynamic movements before progressing toward uneven terrain **Recent Milestones:** Project Echo won the Student Award at the Regional Robotics Awards 2026 and is advancing to the national final at FuturePulse 2026 in Eindhoven.

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
