A fluidic connector intended to enable the circulation of a fluid and includes two parts configured to be coupled, each of the parts comprising a channel, the two channels communicating when the two parts are coupled, the fluid being intended to be conveyed by the two channels, and a locking mechanism configured to bear on a first of the two parts and to exert a force on a second of the two parts in order to hold the two parts in position when the two parts are coupled, the locking mechanism passing through an opening in the first of the two parts.

Easy to manoeuvre fluidic connector

This controller, between a fixed base () and a control handle (), comprises three similar arms () of which each comprises three links () jointed between the base and the handle platform by a pivot (), two rotation joints (and) and a ball-joint (). This controller with six degrees of freedom includes force feedback motors at the first and second joints (and) of which the first is fixed to the base () and the second to the first link (), so that the first is immobile and the other has scarce movement; the third joint () is free. The resulting structure is simple and light not requiring any parallelogram, and kinematic singularities are greatly reduced.

Control unit with three parallel branches

Appliance such as a two-legged robot made up of a system giving ground support and an upper body ( ), equipped with a gyroscopic rotor wheel ( ) which acts as a fulcrum to balance the appliance when positioned in reverse pendulum. A satisfactory equilibrium is guaranteed, thereby releasing from this function the command system in charge of robot locomotion or pathway.

Appliance stabilized by a gyroscope, in particular a two-wheeled robot

Vehicle able to lay a specially designed track formed from elements (5, 6, 7) joined end to end. The vehicle (8) advances along the track and carries a track element on the carriage. When it reaches the end of the track, the carriage is lowered so that the element can be fitted into the preceding element. The elements are of different types so as to permit track height and direction changes.

Vehicle for the automatic laying of a track by a vehicle travelling on

Modular element of module (M) for an articulated vehicle formed therefrom. The vehicle must be able to travel over various obstacles (corridors, staircases, level changes). The modules (M) are joined by double hinges (20) and have internal degrees of freedom (flexible chassis, twisting displacement, adjustment of the pitch of the load 69), so that the vehicle is given flexibility and stability. The vehicle is intended to operate in hostile or dangerous environments.

A system determines the movement of a track vehicle along the ground, the track vehicle having at least a first rotatable, endless track for supporting the vehicle on the ground, a drive for causing the movement of the vehicle, and a turning system for changing the direction of the movement of the vehicle. The system has a first traction-improvement device for mounting on the track vehicle. It bears on an inner-surface side of the first track with sufficient pressure for a small-surface portion on the opposite side of the first track to engage the ground with a higher pressure than any other portion of the first track, whereby to locate a pivoting axis of the track vehicle in the vicinity thereof. A first speed sensor for mounting on the track vehicle in the vicinity of the small-surface portion on the opposite side of the first track senses the speed of movement of the track vehicle along the ground only in the direction of the rotation of the first track and provides a first information thereof, whereby the movement of the track vehicle may be deduced therefrom. Preferably the vehicle has two tracks, and the system has two such traction-improvement devices and speed sensors respectively for the two tracks.

System for determining the movement of a track vehicle

The vehicle comprises two tracked bodies and one non-tracked body articulated about a common axis. Each tracked body comprises two laterally positioned tracks. The engines are carried by tracked bodies, one of them supporting an engine or motor driving the tracks located on one side of the vehicle and a motor or engine controlling the articulation of the tracks bodies with respect to one another, whereas the other tracked body supports a motor or engine for driving the tracks located on the other side of the vehicle and an engine or motor controlling the orientation of the non-tracked body about the axis. The non-tracked body supports the main useful load.
