Semi-teQ II
Posted 3 Weeks Ago at 09:56 PM by seesoe
hello all, i currently have an unfinished wifi bot called semi-teq, the build can be found here. that was my first robot that i built when i was 17. its pretty messy and half assed, but the past few years i have learned tones of things, like the build mistakes i made with semi-teq I. the original project was supposed to an 18 wheeler type robot shape, with a tailor to go with it, hence the first part semi, teq stands for technology, but with a q at the end instead of ch because the controller im using is from RoboteQ.
enough intro, out with semi-teq I, and in with semi-teq II.
i parted out the old robot already, and started laying out the new one, the old frame was welded together by me and a friend and we had drive alignment issues. so im going to build the new one out of slotted metal angle steel.
the new design will be like a truck (simple bed and all). im going to take extra care to make the frame as square as possible, it really messed up the old robot a lot.
the old robot was rear wheel drive with casters in the front, but i hated how the casters had to pivot in place and distort the drive pattern. i decided i will make semi-teq II AWD
, however im only going to use to motors (left back front, and right back front). there will be a lot of chain and stuff on the inside this time, especially due to the fact that i decided that i want this robot to be raised.
the old robot had the motor on the side of it, and the shaft came out like an inch off the bottom of the frame and the tires are about 13 inches high, so that placed the robot at about 5.5 inches off the ground. this time around the robot will be the full 13 inches off the ground by more chain and sprocket stuff.
on each corner i will have a v coming down for the wheel to be mounted on and the chain to be run down. i am also working on suspension ideas by removing on of the legs on the v and replacing it with a shock absorber, possibly pneumatics for some hydraulics :P
the old robot's base was 17x30 inches, the new one will be 40x20.
words can only say so much, ill try and work on a quick autocad drawing of what i just all explained.
till then, Mc Master Carr and Google is your friend
cheers
