to put it nicely: if there is something dangerous you can get to, kids WILL get to it sooner or latter. chains and gears have to be accessible so they can be greased. chains and belts have to be accessible so they can be put back on if they come off or break. If you have to have these things, bolts with unusual heads (and maby a lock washer or lock nut or both) is a good idea to slow kids down.
also, stay away from small bolts as the heads strip faster the smaller they are and don't have wires within drill length of bolts... we don't want someone thinking they are being smart and drilling out a striped bolt and accidentally electrocuting themselves/shorting it out/ stopping the robot from working.

if you run the chain through aluminum box tubing then there is no way to get to it without making it un-dangerous
