In this video, Brian introduces you to TobyJnr, a bot that he uses in the next several videos to teach you many key things about IoT development.
TobyJnr is based on the TJBot open source project. To build your own TJBot, you can either download design files to print/cut your own or you can buy a kit from the TJBot site. Watch this video if you need help building your TJBot.
Documentation and instructions, including the list of hardware and Raspberry Pi configurations, can be found in the TobyJnr wiki.
