The design of a throwable two-wheeled reconnaissance robot

Miniature throwable robots are suited for urban war, anti-terrorism, rescue and some other emergency case for its light, low cost, small and convenient to deploy. This paper designs a throwable two-wheeled reconnaissance robot BHTBOT-3. The key structure of BHTBOT-3 is based on co-centric shaft structure which solves the restriction of drive shaft diameter. The bamboo-inspired outer shell makes its strength increased by 300% while the weight increased only by 20%. The process of non-linear drop impact is simulated by LS-DYNA based on BLATZ-KO material model. The tire is improved with the analysis of the simulation result. The final experiments show that BHTBOT-3 can survive after the throw to the ceramic tile flooring from 10 meters high stair.
