Rob Lass's Course Project
The current robot is a six legged walker inspired by the composition of ants. I got all the pieces I needed today (10/10), and put it together only to learn that one motor was not enough to power the legs once I put it on the ground. I tried using two motors, but I think some of the ports on my handyboard are dead. I was unable to turn both on simultaneously. My current plan is to buy a 9v battery and just use that to power the two motors.
Old Inchworm Robot
I found out wheels were not allowed. So, I took it apart to make the six-legged walker instead.
The robot is in the correct shape, and the motors have been added. They both work, but I only have one cable for connecting a motor to a Handyboard, so I can't power them both until I find another one. I also need to add the sensors to toggle the motors when the robot's "hump" is fully up, or fully down.
The motors are strong enough to pull the robot in its current form, so I assume that means it is feasible.
I still have some photos of this that I took before I disassembled it, I'll post them the next time I download from my camera.
The robot will not work on the carpet in my room; there is not enough traction. It works on the tile floor in my kitchen, and I assume that is good enough.
I tried out a number of different animals before I found one that seems feasible. My first idea, a hopping robot, turned out to be too hard to implement with the materials available. I played around with the lego kit one night while going through a biology textbook, and decided to go with an inchworm-like robot.
