Google has no way of knowing when you hit your own site with your own bot. Google can't see anything that happens on your server.
Even if you use Google Analytics, your bot won't show up in it. Google Analytics relies on client side JavaScript to record hits. Most bots don't execute JavaScript. If your bot does execute JS, you should be able to configure it not to hit www.google-analytics.com
so that it doesn't execute the GA snippet. Alternately you could configure your web site not to include the GA tracking snippet when your bot hits.
Even if hits do show up in Google Analytics, Google says that it doesn't use GA data for ranking purposes.
Even if Google saw your bot hits in a place that it could use them for ranking purposes, it is unlikely that they would effect your rankings. Sites get crawled by bots all the time. In fact, more than half of all web traffic is bots, not actual users. There would be no reason for Google to adjust rankings based on whether or not a site is getting hit by a bot. I would just make sure that your bot uses a user-agent header that clearly identifies it as a bot.
The only way that this crawling could effect your SEO is indirectly. If this crawling were to slow down your site significantly to the point that users were getting frustrated, Google could notice that and adjust your rankings because of perceived performance problems or poor usability.
