The crawler frame is created through the precision sand casting of aluminum alloys.Our unique casting technology enables a strong, thin, and weight-saving frame. We also conduct an X-ray CT inspection to enhance the products' reliability and ensure the frame is free of potential casting defects (such as blowholes).
Special Glass for Explosion-proof Robot
Various shapes of tempered glass such as flat, cylindrical, and dome glass are available for explosion-proof standards.
Global LTE/Wi-Fi router and explosion-proof antenna
The LTE router with support for a wide range of operating temperatures and the newly developed explosion-proof antenna with wideband and high-gain technology enables IoT communication in harsh environments for remotely managing the operating status of the robot.
EX ROVR features special crawler belt shapes which are suitable to challenging applications. The track's unique polyurethane compounding paired with molding expertise allows EX ROVR to achieve optimal traction and power transfer even in severe conditions.
Explosion-proof High-capacity Lithium Ion Battery
The battery management system includes powerful features such as power control over the flameproof container wall and interlocked power shutdown in the event of protective gas pressure drop. These advanced features contribute to a significant size reduction of the flameproof battery container.
Downsizing of Explosion-proof Battery and Camera
Utilizing technique and know-how of the explosion-proof apparatus manufacturer, a lightweight flame-proof battery case balances the explosion proof and the mobility of the robot, and a compact flame-proof camera case acquires the visibility of the hand eye camera.
Ultra-compact, Network-based Servo Driver
The ultra-compact servo driver Gold Twitter (manufactured by Elmo) that supports DC power is compatible with a wide range of motors with high controllability and versatility. In combination with the motion controller Platinum Maestro, multiple drivers can be flexibly controlled via CAN Open.
Enclosure-based explosion-proof design
- Sophisticated explosion-proof interlock and pressurized enclosure design enable a light-weight mobile robot.
- Charging station provides protective gas recharges for the robot.
- EX ROVR automatically navigates back to the optimal charging position to ensure proper terminal connection and contact.
