We've tried to give our robot a reasonable amount of ground clearance, but this has created a slight issue when it comes to mounting our VL53L0X Time-of-Flight ranging sensors, if we mount them to the body they'll sit too high and might end up looking over the walls in some of the challenges, this is clearly far from ideal.
Another possible issue that I foresee is damage to the little gearboxes on the micro metal gear motors that we use. These little gearboxes are pretty fragile at the best of times, but we've opted for larger wheels this year, putting even more strain on them. I don't think it would take many bumps into a wall to cause problems.
So, how do we solve these issues? Well, hopefully we've solved them with a single solution, Bumpers.
The thought process behind this is we install bumpers to protect the wheels and gearboxes against collision damage and we make end caps for the bumpers which we can then mount the sensors to.
Will they work as planned? Who knows, but there's only one way to find out.
