Mech Warfare

 

 

COMPETITION

The goal of Mech Warfare is to build an airsoft enabled quadruped robot that is ready for one-on-one robot combat, piloted through a wireless first-person POV system. Competitors battle out their robots in an Airsoft war that mirrors the scenarios found in sci-fi universes such as Battletech, Warhammer 40k and Armored Core.

The Mech Warfare competition takes place in a miniaturized city contained inside a cage (to protect the audience!). Mech robots, representing schools across the country, navigate the blocks and cities of the cage with mounted airsoft guns and attempt to downpour a rain of lethal BBs onto their opponents. The robot that hits its opponents the most and gets hit the least wins.

MECHWARFARE 2016

In 2016, the Mech Warfare team travelled down to West Virginia’s Sheperd University to compete in ShepRobo Fest, an annual robotics competition hosted by Sheperd that features several competitive events. Six robots entered the Mech Warfare competition. Only one emerged victorious. After multiple rounds of intense robot skirmishes involving heavy BB combat and even one competitor’s leg-motor catching on fire, we are proud to announce that Harvard’s Undergraduate Robotics Club claimed First Place in ShepRobo Fest's 2016 Mech Warfare Competition!

 

MECHWARFARE 2017

Mech Warfare defended their title at Sheperd University's Mech Warfare competition, placing first for the second year in a row - however, this time we dominated the competition with a new design. Our Mech Warfare 2.0 or Baby Mech - as we called it - featured a 350-fps metal BB gun, a plywood frame and dynamixel servos. Baby Mech then traveled to compete at Robo Games in California, achieving 6th place after a number of close matches. 

 

We are currently working on a new iteration of our Mech Warfare robot to compete in 2018!

2016 Design Specifications 

  • Home-built lasercut acrylic and 3D printed PLA body.
  • 14 High-torque servos connected to an 18 channel servo controller to control the turret and legs.
  • Hip, knee and ankle rotation on each leg.
  • Controlled remotely with a Wii Nunchuck via XBee communications.
  • Arduinos constitute the computer processing on both the transmitting end (Wii Nunchucks) and the receiving end (the robot itself).
  • Independent on-board WIFI camera for transmitting a video feed of the battlefield.
  • Armed with an airsoft gun assembly, which is fed BBs from an electric airsoft hopper.
  • The gun and hopper are triggerd using a relay
  • The entire robot is powered by a 7.4V 4000mAh LiPo battery through a buck converter.

2017 Design Specifications

  • Lasercut baltic birch plywood body - a lighter and more durable material. 
  • 15 high torque servos ( 3 12AX Dynamixel servos on each leg, 18AX Dynamixel servos for controlling turret tilt, turret pan and a 12AX Dynamixel servo to reload the BB magazine).
  • Servos controlled using raspberry pi.
  • Pi's onboard camera connected to local wifi router and transmitted video feed of the battlefield (switched to FPV camera after Shep competition).
  • Remote control via wifi network using game controller connected to a computer on the network. 
  • Inverse kinematics used to determine optimal foot placement. 
  • Improved shuffle gait - designed to make the robot walk, strafe and rotate.
  • 350-fps metal airsoft gun and gravity hopper. 
  • High amp relay connected to the Pi controls gun. 
  • Entire robot is powered by a 11.1V 4000mAh LiPo battery (with a 5V voltage converter for the Pi).
