Mobile Robot Servosila "Engineer". The mobile robot is designed for applications where an environment or a nature of engineering operations pose a risk to human life: Disaster Response, Firefighting, Public Safety, Search and Rescue, Industrial Engineering and Maintenance and Maintenance of Tunnels and Pipelines. The robot is also used as a Research and Education platform.
The robot has a modular construction which simplifies its maintenance and reduces the cost of ownership throughout its service life. It features between five and seven degrees of freedom depending on a chosen configuration. Its robotic arm is capable of lifting loads and reaching substantial heights. The robot has a durable, but light-weight metal body, hardened electronics and a sensors package, capable of withstanding the stresses and rough treatment.
Lightweight robot transportable in a backpack. The robot is designed to have as small weight and footprint as possible while still meeting the requirements of being able to climb stairs and raise the sensor head high enough to look inside parked cars. The robot fits inside a regular backpack and can be simply carried to a mission area by its human operator. Backpack transportability is a required feature when it comes to using the robots in hard-to-access areas where transportation by cars or trucks is impossible.
Simple to use. The mobile robot is rugged, simple to use, does not require much expertise or heavy training for successful application. The robot is controlled via a virtual reality glasses and a joystick. The virtual reality glasses display video streams coming out of the video cameras installed in the sensor head of the robot. The joystick is used to control the motion of the robot including its gripper. It takes half an hour for an average person to fully master control of the robot.
A heavy duty machine. The robot is designed for outdoor use. The robot is watertight, capable of operation in the rain, dust and snow.
Stairs climbing. A tracked chassis of the mobile robot is specifically designed for climbing stairs of high-rise buildings in industrial, urban and rural environments. Remote visual inspection of high-rise buildings is a key mission scenario.
The small size of the robot enables it to easily traverse doorways and narrow passages either inside damaged buildings or outdoors while carrying a powerful array of sensors and tools.
A pair of auxiliary flipper threads helps the mobile robot climb stairs and negotiate obstacles in industrial, urban and rural environments.
Self-Leveling, The mobile robot is capable of leveling itself from sideways or upside down positions. This capability greatly improves operational persistency of the robot in a target area of operations. The robot can seamlessly recover from mistakes made by its human operator thus increasing the chances of success.
Robotic Arm Manipulator. The robot is equipped with a robotic arm which enables the robot to perform dirty or potentially dangerous engineering operations remotely. The arm is capable of lifting heavy loads off the ground for carrying them for inspection in a safe location. The arm is a flexible remotely-controlled tool that can grasp, push or pull objects. Door opening is an important task performed by the robotic arm. The robot is capable of opening different doors either by employing the gripper of the arm, or by using special tools.
The arm is made of servo joints and rigid segments that connect them. The more joints are included into the configuration, the more degrees of freedom the arm obtains, and the more of a flexible tool the arm becomes. A two-segment arm allows the robot to reach out much further away from the chassis, or much higher up, and enables applications such as visual automobile inspection, and handling of potentially explosive objects. Such a two-segment arm comes with either two servo joints or with three servo joints. Both of the arm configurations enable a very flexible remote object manipulation, while the arm with three-servo joints has some advantages in confined areas where the chassis motion is restricted, such as tunnels or cellars.
A one-segment arm significantly increases mission capabilities of the robot. Such a robot can raise its sensor head, and use a gripper to grab objects from the ground or tabletop. A single segment arm can come with one servo drive joint, or with two servo drive joints. A single-segment-arm configuration can be enhanced by adding a gripper, or a rotating gripper. The rotating gripper allows the robot to rotate door handles to open doors in buildings. The gripper enables robots in such a configuration to perform many kinds of disaster response or public safety missions including removal of dangerous objects from populated areas.
In the simplest case, there is no arm at all, and the robotic head is mounted directly on the top of the turret servo mechanism. A non-actuated rigid extender neck is needed to move the center of gravity towards the middle of the robot. This kind of lightweight but very capable configuration is designed for reconnaissance or visual inspection missions, or for carrying mission payloads that do not require a robotic arm for operation. It is worth noting that a gripper can be added to this configuration as well, primarily for delivering and dropping of objects at desired locations.
Grippers and other Tools The mobile robot can be equipped with a rotating or a regular gripper that can capture and carry objects. The grippers are used to manipulate objects while performing engineering operations or visual inspection missions. Additional tools such as a drill or a circular saw can be installed either in place of the gripper, or on the gripper itself. Choose a rotating gripper over a regular gripper, if a mission profile calls for opening doors by rotating door handles, or if an extra degree of freedom of the gripper is required for precise object manipulation. The gripper can also be excluded from the configuration, if the arm of the robot is to be used for carrying mission-specific payloads, for example, flame-retardant grenades or ground- or wall-penetrating radars, rather than for object manipulation.
