GALILEO Robotics Exploration

SEC. 01 / ROVER

The rover

Four subsystems, one goal: mobility, robotic arm, electronics and autonomy engineered to complete the tasks of the European Rover Challenge.

SUBSYSTEMS

SS-01 / MOBILITY

Six wheels, no roads

The rocker-bogie suspension keeps all six wheels on the ground over rocks and slopes, with no springs. Each wheel has its own motor: the rover can turn in place and climb obstacles as tall as a wheel.

  • Independent steering on the four corner wheels
  • Passive load balancing, no active suspension
  • Grousers for traction on loose sand

SS-02 / ARM

Manipulating at a distance

The arm reaches panels, switches and samples built for human hands. Its kinematics are redundant to work in constrained poses, with an interchangeable end-effector for the different competition tasks.

  • Enough degrees of freedom to orient the tool
  • Modular end-effector: gripper, driver, probe
  • Teleoperation with visual feedback from the head

SS-03 / ELECTRONICS

The nervous system

Power, distribution and telemetry run on boards designed and tested by the team. The goal is resilience: terrain vibration, thermal swings and dust must not stop a run.

  • Protected, monitored power bus
  • Real-time telemetry to the control station
  • Redundancy on critical paths

SS-04 / AUTONOMY

Deciding on its own

In the autonomous task there is no teleoperation. The rover builds a map of its surroundings with stereo vision, finds the markers and picks a path around obstacles, with no human input.

  • Visual odometry and real-time mapping
  • Competition marker recognition
  • Path planning with obstacle avoidance
