A two wheeled throwable robot comprises an elongate robot body with an axis supporting two drive wheels and a rearward tail extending from the robot body. The robot body comprising an elongate chassis with two ends, a motor at each end, the motors connecting to the drive wheels through gear and clutch systems supported by the chassis, sensors and operational components positioned at the front of the chassis, processing circuitry, radio, memory, power control circuitry are located in the chassis such as the circuitry compartments and may be sealingly contained therein. The chassis having a main chassis body that provides enhanced structural strength by supporting the drive motors in conforming bores and having a plurality of U-shaped recesses for receiving a forward chassis body component and a battery module. Additional recesses on the ends of the main body component, along with end chassis caps define drive system compartments for gear systems and clutch mechanism that are isolated from the interior circuitry compartments and the drive motors.
