Robotic vehicle

A skid steer drive robot comprising:

• a skid steer drive;
• a drive wheel and a first volume defined within the skid steer drive adjacent the drive wheel;
• a load shifting assembly including a tilt motor, the load shifting assembly defining a second volume adjacent the tilt motor;
• a chassis defining a third volume adjacent the drive wheel;
• and
• motive power elements distributed among the first volume, the second volume, and the third volume, the motive power elements comprising a battery assembly, a main drive motor assembly, and a load shifting motor assembly, wherein the first volume houses the main drive motor amplifier and the load shifting motor amplifier, the second volume houses the battery assembly, and the third volume houses the main drive motor and the load shifting motor.

A skid steer drive robot comprising:

• a skid steer drive;
• a drive wheel and a first volume defined within the skid steer drive adjacent the drive wheel;
• a load shifting assembly including a tilt motor, the load shifting assembly defining a second volume adjacent the tilt motor;
• a chassis defining a third volume adjacent the drive wheel;
• and
• motive power elements distributed among the first volume, the second volume, and the third volume, the motive power elements comprising a battery assembly, a main drive motor assembly, and a load shifting motor assembly, wherein the first volume houses the main drive motor amplifier, the second volume houses the battery assembly and the load tilting motor, so that the battery assembly tilts together with the load shifting assembly, and the third volume houses the main drive motor.

A mobile robot comprising:

• a skid steer drive having a drive wheel and defining a first volume adjacent the drive wheel;
• a load shifting assembly defining a second volume;
• and
• a chassis defining a third volume adjacent the drive wheel and a through space configured to receive the load shifting assembly;
• motive power elements distributed among the first volume, the second volume, and the third volume, the motive power elements comprising a battery assembly, a main drive motor assembly, and a load shifting motor assembly.

An environmentally sealed mobile robot comprising:

• a skid steer drive defining a first volume;
• a cast unitary load shifting assembly defining a second volume;
• a cast unitary chassis defining a third volume adjacent the skid steer drive, the third volume internally connected to a fourth volume defined by the chassis adjacent the first volume by a chassis passageway defined by the chassis;
• and
• a sealed linkage defining a linkage passageway therethrough connecting the second volume and the third volume;
• and
• wherein the third volume houses a main drive motor, the first volume and the fourth volume hermetically house a main drive motor amplifier delivering power to the main drive motor through the chassis passageway, the second volume hermetically houses a battery assembly and the load tilting motor so that the battery assembly tilts together with the load shifting assembly, the battery delivering power to the main drive motor amplifier and main drive motor through the linkage passageway.
