Overview Design –Combination Square –Caliper Fabrication –Hacksaw –File –Drill –Sandpaper/Steel Wool –Shears Assembly –Allen Key –Wrench and Adjustable Wrench –Screwdriver –Ratchet –Riveter –Tape –Ziptie
Caliper Used for precise measurement up to the ten- thousandths place Useful for measuring shaft and hole diameters Also use to figure out tolerances more precisely
Combination Square The combination square is used to measure to the the tenths and also used to make sure that surfaces are level Can be used to see if a surface is level.
Hacksaw Use when accuracy is not an issue Very “crude” cut and not used unless necessary Always push away from you. Never two directional motion.
File Smooth out edges Use to “make stuff fit” One directional motion similar to hacksaw
Cordless Drill Useful for drilling holes, removing rivets, and tightening screw. Use it when you don’t need accuracy as much. Use mostly for wood avoid for aluminum and never use for steel.
Sandpaper/Steel wool Used sandpaper on wood to smooth out edges Use steel wool to polish surfaces You can use it partially to “make things fit”
Shears Use these to cut polycarb There are three different types one to cut to the right one to cut to the left and one for a straight cut. Very rough cut Not for precision
Allen Key Used for socket cap screws or hex bolts. 5mm is the most common on our robot because it is used for Bosch. If you hold the longer end with your hand you get more torque.
Screwdriver Used to tighten flathead or “cross” screws.
Wrench/Adjustable Wrench Used to tighten nuts on bolts. Use the correct size when possible rather than using the adjustable wrench all the time.
Ratchet Ratchet has the same function as the wrench but easier in some situations. Use it when you don’t have too many degrees of freedom because it is easier to tighten.
Rivet A piece used to connect two pieces of metal by clamping them together. They are useful when they are properly done. Use aluminum rivets because they are easier to take out.
Rivet (cont.) Consists of several parts: the shank the “Head” and the pin.(seen on the previous slide)
Rivet (cont.) The metal pin is taken out and with it the other end of the rivet is crushed to clamp the pieces of metal together.
Riveter The tool used to take the pin out of a rivet and clamp it to an object. To take out a rivet you have to drill out the shank of the rivet. (see previous diagram)
Zipties Used to mainly keep wires in place. Use for short term if it is on a mechanical component, but switch it out for the long run.
Tape Use when prototyping Try not to have any tape on the final robot.
