Mechanical Engineering Project Help: Stair Climbing Robot
Hello everyone!
First post on the forum, wondering if I could get your guys' input on a project, specifically with motor selection. Im building a stair climbing robot with a budget of $300 (some components already supplied), and have decided on the following features/components:
-Track design
-2 Motors at back
-Aluminum frame (L bracket on the sides, with supporting members going across)
-ABS platform in middle to house electronics
-12V Battery/ 4200 mAh (already supplied, http://www.batteryspace.com/nimhbatt...rccarboat.aspx)
-Sabertooth Driver, 25A 6V-25V (already supplied, http://robotshop.com/ca/en/dimension...ooth-2x25.html)
-myRIO microcontroller used with xbox controller for controlling robot movement (programming done with labview)
The front angle will be made out of a smooth lightweight material, as this will angle the robot upwards to climb stairs.
I need some help in choosing the correct motors specs, as I would like to get motors that had a direct power transmission to the wheels without the need of gears (if this is not a good idea or there is better alternatives, please let me know. The simpler the better though!).
PS- I have a 3d printer for printing customized parts
The weight of this robot will likely be in the range of 10-15 lbs.
The attachment is a rough geometric layout of the robot
THANKS!
Greg
