A close-up on the corner of ALARM’s 2009 robot, pre-steering. The inside of the module has the right angle gearbox from a Dewalt grinder and a set of sprockets to drive the wheel. Steering belt attaches directly to the cog pattern on the outside.
These modules were made with generous help from Ramco, one of our machining sponsors.
