The Science of Mammoth: Designing a Hydraulic-Powered Robot

The Science of Mammoth: Designing a Hydraulic-Powered Robot

Mammoth is a heavyweight robot that competes in the BattleBots television series. It was first introduced in the 2020 season and was built by a team of engineers from MIT. The robot has a unique design with long, articulated arms that can lift opponents and throw them out of the arena. Mammoth’s main weapon is its lifting arms, which are powered by a hydraulic system. The arms are made of carbon fiber and can lift up to 250 pounds. The robot also has a flamethrower mounted on the front, which can be used to distract opponents or cause damage.

Mammoth’s design is not particularly durable, as it is made mostly of lightweight materials and is vulnerable to damage from spinning weapons. However, its unique design and weapon make it a popular competitor among fans of BattleBots.

In the 2020 season, Mammoth had a record of 2 wins and 2 losses, including a victory over Axe Backwards and a loss to Copperhead. The robot did not compete in the 2021 season but may return in future seasons of BattleBots.

The Science of Mammoth: Designing a Hydraulic-Powered Robot

How it is developed?

The team from MIT that developed the Mammoth heavyweight robot consisted of several engineers with experience in robotics and mechanical engineering. They began by designing the robot using computer-aided design (CAD) software, which allowed them to create detailed 3D models of the robot’s components and test their functionality before building anything physical.

The team then sourced the necessary materials and began constructing the robot’s frame, which is made of lightweight aluminum. They also designed and built the hydraulic system that powers Mammoth’s lifting arms.

One of the key challenges the team faced in developing Mammoth was creating the long, articulated arms that make up the robot’s lifting mechanism. These arms had to be strong enough to lift heavy opponents, yet flexible enough to allow for a range of movement. The team ultimately decided to use carbon fiber to construct the arms, as it is both strong and lightweight.

Once the robot was constructed, the team tested it extensively to ensure it was ready for competition. They made adjustments as needed to improve its performance and durability.

Overall, the development of Mammoth was a collaborative effort among the MIT team members, who brought their diverse skill sets and expertise to the project.


Programming Language:

It is unlikely that Mammoth’s developers used traditional coding languages such as C++, Python, or Java to program the robot. This is because BattleBots robots typically use microcontrollers and specialized software to control their movements and weapons, rather than relying on a traditional programming language.

The specific control systems used in Mammoth would depend on the preferences of the MIT team and the specifications of the robot’s hardware. However, it is likely that they used a combination of microcontrollers, sensors, and specialized software to control the robot’s hydraulic system and lifting arms.

In general, programming BattleBots robots requires a solid understanding of electronics, control systems, and robotics principles. The development process typically involves designing and building custom circuit boards, writing firmware to control the microcontrollers, and testing the robot’s performance in real-world scenarios.


Hardwares used

The MIT Mammoth heavyweight robot consists of several different parts and components, including:

  1. Frame: The robot’s frame is made of lightweight aluminum and is designed to be strong enough to withstand impacts from other BattleBots robots.
  2. Wheels: Mammoth uses four large wheels to move around the BattleBox arena. The wheels are designed to provide good traction and maneuverability.
  3. Lifting arms: Mammoth’s unique lifting arms are its main weapon. They are made of carbon fiber and can lift up to 250 pounds. The arms are powered by a hydraulic system and are designed to be flexible and articulated, allowing for a range of movement.
  4. Hydraulic system: The hydraulic system is used to power Mammoth’s lifting arms. It includes a pump, valves, and hydraulic fluid to control the movement of the arms.
  5. Flamethrower: Mammoth also has a flamethrower mounted on the front of the robot. The flamethrower is powered by propane and is used to distract opponents or cause damage.
  6. Electronics: Mammoth’s electronics include a variety of components, including microcontrollers, sensors, and custom circuit boards. These components are used to control the robot’s movements and weapons.

Overall, Mammoth is a complex robot with a variety of specialized parts and components. The MIT team worked to design and build each component to maximize the robot’s performance in BattleBots competitions.
