Bringing mobility in your experiment

The IoT-LAB provides robots to reach application scenario involving mobility

IoT applications involve mobile entities with either controlled or uncontrolled mobility. Uncontrolled mobility can be either predicable or non-predictable.

So, we plan to offer to the user 3 different types of mobility to use with the robots.

Flexible Types of Mobility



The fixed circuit-based mobility offered in the IoT-LAB today falls under the “predictable uncontrolled mobility” class. This is representative of applications such an IoT devices embedded in a bus following a pre-determined route.

Circuits of each site are listed on GitHub.

Mobility Model

Work In Progress

Two additional mobility models are being added to support unpredictable mobility with predefined behavior:

  • random waypoint mobility: the robot repeatedly selects a random destination inside the testbed and navigates to it;
  • Manhattan mobility: the robot moves along (virtual) horizontal and vertical lines, and select it heading randomly (continue straight, turn left/right) at each intersection. This mobility pattern is representative of some urban areas.

User Controlled Mobility

Work In Progress

In applications such as a swarm or robots of a fleet of self-driving cars, the mobility is controlled. To reproduce such scenarios, user controlled mobility is being implemented. In the same way as firmware is deployed on sensor nodes, the user will be able to uplad a mobility model. To guarantee the integrity of the software running on the robot, the user’s mobility model will execute in a sandbox environment.

Robots deployed



is an open-source robot with a maximum speed of 0.7m/s and an odometry of 2578.33 ticks/wheel. It is equipped with a netbook (Asus X200CA). Two sets of batteries are present in this robot: a 3000mAh battery for the netbook, and a 4400mAh battery to power the motors. This allows the robot to run for 3 hours, and fully recharge in 6 hours. An infrared beam allow the robot to find its docking station, where it recharges.



is a high-mobility 4×4 platform with 4 brushless motors and 4 hall encoders. It is equipped with a single-board computer based on an Intel Atom dual-core. Since no off-the-shelf docking station is available for this robot, the IoT-LAB team developed one capable of charging two robots. The robot uses its two infrared sensors and camera to align in front of the docking station, marked by a QR code, moves forwards, and shuts down its motors once it starts charging.
