Robot Dog Achieves Milestone with CMU Balance Beam Challenge

From an evolutionary standpoint, it makes sense that we’re not built particularly well for humanoid robots. We’re on the wrong side of the human-ape line of development; while apes are physically capable of taking on humanoid robot form, humans are not as developed in this area. This means that we have to build our humanoid robots based on a different design philosophy than those used for automatons like Baxter or Sawyer — and even those used for human-like forms like Sony’s Aibo dog toy.

For centuries, humans have relied on design to create products that are both functional and aesthetically pleasing. From cars to garments, intricate details help make items appear unique and attractive. However, in order to design something from scratch, certain concerns would likely lead a product designer down a different path than what is commonly used today.

One of the main considerations product designers must take into account is function. In order for an item to be useful, it must be able to meet the needs of its users. Designers must also consider how an item will look and feel when it is being used. Additionally, they must consider how people will interact with the product—from picking it up to putting it down—in order for it to be user-friendly and appealing.”

Different types of balance are necessary for different things. For example, the equilibrium of a weight on a scale is important for measuring mass, but it’s not so important when measuring the center of gravity in an object. In short, balance is important when you need to do something precision-wise but not when you just want to stay upright.

The Robotics Institute at Carnegie Mellon University has started constructing off-the-shelf dog robots that are capable of varying degrees of stability in their locomotion. The quadruped is plenty stable in its standard locomotion, but quickly becomes unstable when stuck on top of a balance beam. This challenge fascinates researchers, who are determined to perfect the technology so that these robots can be used for various purposes, including search and rescue operations and helping disabled people navigate difficult environments.

The robot’s success in balance beam walking may lead to new ways of robotic exploration, as robots could potentially explore difficult-to-access areas or negotiate dangerous terrain.

In order to make the hand-walkers work, the team had to find a way to power them. Initially, they thought maybe they could use motors like those found in cars. But that would require an unreliable and inefficient system that would be very difficult to control. So they came up with the idea of using a backpack filled with reaction wheel actuators (RWA). These actuators help control the altitude of satellites, so by rigging up a regular backpack with these sensors, they were able to create small hand-walkers that can navigate around obstacle courses.

A big flywheel with a motor attached is placed on the body of a quadruped robot to create rotational movement. This movement can be used to control the direction and speed of the satellite.

Manchester said it was easy to modify an existing control framework to account for the RWAs because the hardware doesn’t change the robot’s mass distribution, nor does it have the joint limitations of a tail or spine. Without needing to account for such constraints, the hardware can be modeled like a gyrostat (an idealized model of a spacecraft) and integrated into a standard model-predictive control algorithm.

Manchester argues that by capitalizing on the inherent limitations of robotic arms and legs, it is possible to develop a control framework that is robust to variability in robot Mass Distribution (MD). This is because a robot’s MD does not critically impact its movement or behavior, and the physical limitations of a robot’s joints are not as significant when dealing with tasks such as arm and tail manipulation. In conclusion, Manchester envisions this new control framework being used in future industrial robotics applications.

In any situation where a human is not the most suitable option for completing a task, an autonomous robot can be sent in their place. While balance may seem like a mundane characteristic for such machines to possess, it is actually crucial for successful search and rescue applications. With robots able to walk on uneven surfaces and navigate through tight spaces, humans are able to complete these tasks more easily. In addition to saving time, this capability allows for greater flexibility when searching for survivors or objects.
