A robotic mule, a type robot that can move heavy objects, is called a robotic mule. Boston Dynamics currently makes it. Original mule was fitted with a gasoline-powered engine. It makes a lot of noise, and is often compared to a swarm a bees. Boston Dynamics has developed a quieter version. The Spot is powered by electrical and hydraulics. This robot can transport around 40 pounds (18kg). It cannot be repaired.
LS3
The LS3 robotic mule is currently undergoing platform refinement as well as combat simulations at military bases in California, Massachusetts. It is still in need of fine-tuning to improve its efficiency. Currently, it has been nicknamed "Cujo" by its company. It has been used in training exercises and demonstrations at the Marine Corps Warfighting Lab.
The LS3 robotic mule features a variety of sensors and laser radar. It's a powerful follower-the-leader machine that can track a dismounted Marine. Marines can also send commands to the robot.
BigDog
Boston Dynamics is currently developing the BigDog robotic mule for their Defense Advanced Research Projects Agency. It can carry hundreds of pounds and can walk on rough terrain, even snow. The robot can even scale a mountain without falling.
The BigDog robot mule has been in production for many years. Funding from DARPA allowed it to be developed at MIT. The legs of the BigDog are articulated and the system contains an array of sensors. The robot does not require watering or feeding. It runs on a gasoline engine and sounds like a giant chainsaw. The future could see it equipped with a sunroof.
Pedongi
Pedongi (the robotic mule) was an Indian army animal. The animal was named after a small town in West Bengal. The Indian Army had a unit that transported animals and the mule was one of them. This unit used mules in transporting ammunition, store, and casualties from military hospitals.
Pedongi fought in the army over three decades. After retirement in 1998, the mule was given a Vir Chakra award for achieving the longest service of any mule in the Indian army. While the story of Pedongi's life has changed over time, the core story is the same. The 1971 conflict in Jammu-Kashmir saw the mule as part of the Army's Animal Transport Convoy. The mules had been attacked by Pakistani soldiers, but the infantry unit launched a counterattack.
