The logic behind this is to modify the IR transmitter and control two via an Arduino attached to a computer, while adding a ZigBee radio to the third for wireless control.Īfter examining the transmitter PCB, I noticed that there are exposed test points which can be used to attach wires for the forward, backward, left and right switches. HEXBUG is a brand of infrared and automaton toys developed and distributed by Innovation First International. Out of the three spiders that I have, I’ve left two robots untouched while the third one has been disassembled. Heroic Innkeeper, Heroic Strike, Heroic Strike, Hex, Hex, Hex Lord Malacrass, Hidden Cache. I’ve seen a lot of blog posts about hacking these spiders, but after trying to modify the robot’s control PCB to attach wires to the H Bridge driver directly (as in this blog post: ), I’ve decided that it’s easier to replace all the electronics rather than hack the surface mount board. Buccaneer, Buffet Biggun, Bug Collector, Build a Snowman. Both the hand held transmitter and the receiver in the robot are based around the AT8EB one chip microcontroller (Alpha Microelectronics Corp), with the robot itself also containing an ST1155A H Bridge driver. The way it walks is referred to as the Jamius walking mechanism after its inventor (see: ).Īfter taking the Hex Bug apart the construction is actually really good for a cheap toy. Hex Bug Spiders are relatively cheap hexapod robots that are controlled via an infra-red transmitter which has an A or B code so that you can control two simultaneously.
