Product overview
About Honda E2-DR
The Honda E2-DR is a bipedal disaster-response prototype from Honda R&D, with a height of 168 cm and a weight of 85 kg including its battery. Honda R&D presented it at the IROS 2017 conference in Vancouver, in a paper on an experimental legged robot for inspection and disaster response in plants.
According to IEEE Spectrum, the robot is about 25 cm thick, so it can pass through 30 cm gaps, and it has 33 degrees of freedom. It carries a 1000 Wh lithium-ion battery that gives about 90 minutes of operation. The article reports bipedal walking at 4 km/h and quadrupedal walking at 2.3 km/h, and it describes the robot stepping over a 200 mm pipe, climbing 200 mm stairs and climbing a vertical ladder in simulated rain.
The sensor head combines two rotating laser rangefinders, a monocular camera, a time-of-flight camera and a stereo camera. IEEE Spectrum expects the robot to be almost entirely teleoperated, with some autonomy added later. No sales, customer deployment or official Honda product page was found, so the entry is listed as a prototype.
Capabilities
Key features
Slim body for narrow gaps
The robot is about 25 cm thick, so it can pass through 30 cm gaps such as shortcut passages in factories. [1]
Layered sensor head
The head has two rotating Hokuyo laser rangefinders, a monocular camera with an LED flash, an SR4000 time-of-flight camera and a stereo camera. [1]
Dust, splash and temperature tolerance
The article says the robot is dustproof and splashproof and can operate between -10 °C and 40 °C. [1]
