adero is developed to follow pleasant and simple shapes which leads to an attentive and trustworthy appearance. The robot’s presence fits in public and busy environnements and draws attention to itself.
adero reacts actively with its surroundings and creates relationships with people and objects. Using sound and light, the robot draws attention to himself and communicates his state of being. Once the robot arrives at the destination, it builds up a trustful connection to the customer enabling a novel yet intuitive interaction.
For autonomous indoor delivery, it is crucial to know the robot’s exact position. adero is hereby supported by the ETH spin-off Sevensense. Before the first operation, the path to the destination is learned and the environment alongside is mapped using six cameras. While delivering goods to customer, these camera in combination with a dedicated processing unit provide the position in the map and allow us to follow the trained path.
In order to drive safely through the airport, a specific sensor setup was elaborated. 3D time-of-flight sensors detect obstacles ahead of the robot. The thereby obtained data is processed and then fed into an advanced path planning algorithm to avoid the obstacles and yet stay on the path towards the customer. An extra layer of security is provided by a belt of ultrasonic sensors monitoring the close range.
The main structure is composed of an innovative combination of carbon fiber tubes and 3D printed links. This provides maximal sturdiness while keeping the weight low. It is designed to absorb impacts and prevents the robot from tipping over to ensure safe operation at all times. The bottom part hosts the main components, while the upper part encloses the payload and houses our various sensors.
The two wheeled nature of our robot provides high maneuverability in tight spaces and requires a sophisticated drive system. A high performance sensor to measure the robots motion provides accurate information to the computer running the stabilisation algorithm. From there, the motors are actuated 400 times every second to balance the robot robustly and to pursue the planned path.
