How Do Bipedal Robots Work?

Bipedal robots rely on cutting-edge engineering and advanced software to imitate human movement. Their design includes key components:

• Sensors: These help detect surroundings, measure distance, and avoid obstacles. For instance, lidar sensors map out the area, while gyroscopes help maintain balance.
• Actuators: These are the “muscles” of robots. Actuators convert energy into motion, allowing legged robots to bend and step.
• Artificial Intelligence (AI): AI processes sensor data to determine how the robot should move. It calculates where to step, when to shift weight, and how to adjust to uneven surfaces.

A good example is Boston Dynamics’ Atlas, which combines sensors and AI to perform acrobatic moves like running or jumping.

This robot’s ability to adapt is unmatched, showcasing how bipedal robots are pushing boundaries.

Challenges in Bipedal Robotics

Despite their impressive capabilities, bipedal robots face significant challenges that hinder their widespread adoption.

Each obstacle requires innovative solutions to make these machines more practical and efficient.

Energy Consumption

Walking requires a lot of energy – not just for humans but also for robots.

Bipedal robots, with their need to balance, lift legs, and move dynamically, consume far more power than their wheeled counterparts.

For instance, maintaining stability while standing still or walking on uneven surfaces demands constant adjustment, which drains batteries quickly.

This limitation means bipedal robots often have short operational periods, requiring frequent recharges or advanced power sources that are not yet commercially viable.

One possible solution is the use of regenerative energy systems, where energy expended during movement is captured and reused.

Some researchers are also experimenting with lightweight materials and more efficient actuators to reduce energy demands.

High Development and Production Costs

Building a bipedal robot is no small feat. The cost of designing, developing, and producing these machines is a major barrier to their widespread use.

Take Boston Dynamics’ Atlas as an example.

Each prototype costs hundreds of thousands of dollars to build due to the intricate engineering and state-of-the-art components required.

Sensors, AI systems, and actuators all add to the expense.

Mass production could lower costs, but even then, the price of a commercially available bipedal robot remains out of reach for most industries.

Until these robots become cheaper to manufacture, their adoption will likely be limited to specialized sectors, such as research, defense, or space exploration.

Limited Speed

Compared to wheeled robots, bipedal robots are generally much slower. Their design prioritizes balance and adaptability over speed, making them unsuitable for tasks requiring rapid movement.

For example, in warehouse automation, wheeled robots like Amazon’s Kiva systems can transport goods at high speeds on flat surfaces.

A bipedal robot would take significantly longer to complete the same task.

However, researchers are working on improving speed without compromising balance.

By studying human and animal locomotion, they hope to create robots that can move faster while still adapting to challenging terrains.
