Semi-Autonomous Robot for MIT 2.007 Design and Manufacturing I
Scroll ↓
This robot was made for the class 2.007 Design and Manufacturing I. We were given a kit of hand tools and materials to construct a robot to complete a variety of challenges on a game board. It was controlled with a radio controller for manual control and an arduino for autonomous functions.
Demonstration
Here is a clip of the robot performing a test run on the game board. It can be seen performing a variety of tasks that are explained below.
CAD Progression
Mocking up the robot in CAD allowed for rapid iteration and checking of its geometry without having to make the parts.
Most Critical Module (MCM)
To do most of the tasks, an arm with different tools were attached. The pivot for the arm was mounted high and pivoted up allowing it to quickly extend over 13” above the ground while fitting inside of an 8” box.
Multiplier Ring Hook
A ring was connected by a string to a cowbell and spring such that when the ring was pulled it would raise the cowbell and extend the spring. Depending on how high the cowbell was raised, a score multiplier was added. Using a piece of welding rod shaped into a hook, the robot was able to pull the cowbell over 5” to the max height where the spring was exerting 5 lbs of force. It could perform this task in about 4 seconds, faster than any other robot in the competition.
After 2 days of competition against 120 other students in the class, my robot and I emerged with the third place trophy!
