Concept Solidworks Models of my Mini-me robot, our prototype building platform for our final competition robot
This version has two servos with a caster wheel in the front
First prototype from ABS plastic, cut using bandsaw, and here heating joints to bend
The ABS plastic was hard to bend precisely so I switched over to sheet metal
Mini-Me body with all the holes drilled and bent into the proper shape
Servos, wheels, battery, and RC controls attached!
Quick bench-level prototype of a medal-pusher
Model of an under-actuated mechanism to pick a flag out of the ground by closing the gripper arms around the base and then rotating upwards
My gripper arm after machining all the parts and assembly!
A scissor lift to be located behind my picker arm to hold the flags. The scissor lift has a vertical edge to keep the flags from falling out when the robot is on the slope
I design the top bars of the lift to be asymmetrical so when fully extended, the tray will tip downward, dispensing the flags into the bottom chalet
Water-jet support pieces
Bottom Angles brackets machined on the CNC Mill, the slot allows for movement of the bottom rod, and the bottom face will attach the module to the final robot body
Fabricating the Scissor Lift!
Getting closer to finishing
Fully extended
The finished scissor lift!
I will actuate the scissor lift by pre-loading the rods with springs and then rotating a cam on a servo directly underneath the bottom center rod
The top tray to hold flags, made out of sheet aluminum

MIT 2.007 MITSKI Robot Competition
Spring 2013: MIT 2.007 Design and Manufacturing 1 project where we design and fabricate our own individual robots to perform specific tasks. The theme being Skiing this year in honor of the winter olympics, our robots need to be able to ascend/descend steep slopes (up to 60 degrees), collect flags embedded into the slope surface and deposit then into a chalet at the base, obtain medals from raised pedestals, and pull a heavy pendulum for a score multiplier. Should be a fun semester of designing and building!
