Abstract
A motorized module for a modular robotic structure comprises a housing, a first wheel, a second wheel, an elongated structure mounted to the first and second wheels and configured to rotate the first and second wheels. A driver is mounted to the housing between the first and second wheels. A leadscrew is mounted to the housing between the first and second wheels. A transmission drivingly connecting the driver to the leadscrew. A connector is coupled to the leadscrew and configured to move longitudinally along the second longitudinal axis in response to a rotation of the leadscrew, the connector being attached to the elongated structure.

A motorized module for a modular robotic structure comprising:
- a housing;
- a first wheel mounted to the housing and having a first axis of rotation;
- a second wheel mounted to the housing and having a second axis of rotation;
- an elongated structure mounted to the first and second wheels and configured to rotate the first and second wheels;
- a driver mounted to the housing between the first and second wheels, the driver having a rotatable pin extending along a first longitudinal axis, the rotatable pin rotating about the first longitudinal axis;
- a leadscrew mounted to the housing between the first and second wheels, the leadscrew extending along a second longitudinal axis, the leadscrew rotating about the second longitudinal axis;
- a transmission drivingly connecting the driver to the leadscrew;
- and
- a connector coupled to the leadscrew and configured to move longitudinally along the second longitudinal axis in response to a rotation of the leadscrew, the connector being attached to the elongated structure.
A manipulator arm for a modular robotic structure comprising:
- a base module having a first shaft portion extending from a first end of the base and a second shaft portion extending from a second end of the base, the first and second shafts portions extending in opposite directions along a first rotation axis;
- a first module coupled to the base module and configured to rotate relative to the base module about the first rotation axis, the first module including a first pair of interconnected wheels and a second pair of interconnected wheels, the first pair of interconnected wheels having a first wheel fixedly connected with the first shaft portion and a second wheel, the second pair of interconnected wheels having a third wheel rotatably mounted on the second shaft portion and a fourth wheel;
- and
- a second module coupled to the first module and configured to rotate relative to the first module, the second module being drivingly engaged with the fourth wheel.
The manipulator arm as defined in 11, wherein the second module includes a fifth wheel drivingly engaged with the second wheel.
A manipulator arm for a modular robotic structure comprising:
- a first module having a first compartment defined therein between two spaced-apart longitudinal first arm elements;
- a second module coupled to the first module and configured to rotate relative to the first module between a folded position and an extended position, the second module being inserted in the first compartment in the folded position and at least partially positioned outside the first compartment in the extended position.
