If you are part of a class, mount paper panels on the tail and both sides of the
lead Boe-Bot as shown in Figure 8-6.
If you are not part of a class (and only have one Boe-Bot) the shadow vehicle
will follow a piece of paper or your hand just as well as it follows a lead Boe-
Bot.
Replace the 1 kΩ resistors that connect the lead Boe-Bot’s P2 and P8 to the IR
LEDs with 470 Ω or 220 Ω resistors.
Program the lead Boe-Bot for object avoidance using a modified version of
FastIrRoaming.bs2.
SlowerIrRoamingForLeadBoeBot.bs2.
Make these modifications to SlowerIrRoamingForLeadBoeBot.bs2:
The shadow Boe-Bot should be running FollowingBoeBot.bs2 without any
modifications.
With both Boe-Bots running their respective programs, place the shadow Boe-
Bot behind the lead Boe-Bot. The shadow Boe-Bot should follow at a fixed
distance, so long as it is not distracted by another object such as a hand or a
nearby wall.
