Connect a Memsic 2-axis accelerometer and XBee RF module to the BASIC Stamp HomeWork board and load some code, and you've got a wireless tilt controller. Connect a second XBee RF module to a BASIC Stamp SumoBot board (or Boe-Bot) and load some code into that, and you've got a tilt controlled robot! Since XBee modules can be configured to pair off in different networks, and even on different radio frequencies, you can have multiple pairs of wireless tilt controlled Boe-Bot or SumoBot robots in the same room without any radio interference or crosstalk.

Want to make a tilt controlled Boe-Bot robot instead? No problem, the SumoBot circuit works great on the Boe-Bot robot too.
For each wireless tilt controller + robot, you will need:
- (1) BASIC Stamp HomeWork Board (#555-28188) and a 9 V battery
- (1) Memsic2125 Dual-Axis Accelerometer (#28017)
- (2) XBee modules XB24-API 001 1mW with PCB antenna (#32404)
- (2) XBee adapters:
- (1) of these BASIC Stamp robots, fully assembled and tested
- (1) Piezospeaker (included with the Boe-Bot and SumoBot kits)
- (2) Stickers you can write on, and a pen
- Misc. jumper wires
