Robotics edit

Because this wiki needs a page on robotics.

TCL code edit

CLARAty (Coupled Layer Architecture for Robotic Autonomy) is a robotic control and computer vision library developed by the [JPL], written in C++ with Tcl bindings.

A wish list for tcl packages for use in open source robotics projects. (This list was admittedly built by an amateur):

  • native installed Tcl/Tk on the most common Raspberry Pi distributions". Raspberry Pi3 updates includes TCL/Tk 8.6.
  • a tcllib-like library for manipulating GPIO (inputs, controllers, feedback display, etc.) and interacting with a standard set of peripheral devices. (Check out piio - is there a version that does not need compiling?)
  • a tcllib-like library that interfaces to RTIMULlib for interacting with raw magnetometer/gyro/accelerometer sensor data and calculated corrections to create an inertial measurement unit (IMU).
  • a tcllib-like library of algorithms for managing common robotic activities (movement, maze-solving, line-following, obstacle avoidance ,etc.)

Learning Resources edit

Robotics Competitions and Challenges edit

Does anyone know of Tcl being used in any competition projects?

Projects edit

Commercially available toys and hobby kits

  • Lego Mindstorms - Lego provides an EV3 programming software to connect and control components. Check out the TclRCX page for a Tcl development environment for Mindstorms. Note: the links here and here seem to be dying. Does anyone have a reference to the most current version and some examples?

DIY projects

Projects you can build at home from scratch. Any plans available out there?

Robotics projects and kits for teaching children about technology

  • littleBits - component-based educational kits that connect together with magnets which allow young children to assemble working devices in seconds, and experiment with modifications. There is an Arduino coding kit available.
  • OzoBlocky - Makers of Ozobot Bit (video here), a small, programmable robot used to teach block programming.
  • Circuit Playground - A small hardware board with integrated sensors and outputs (LED, MIDI and gpio) from Adafruit intended for introductory learning about electronics. It comes with a complete set of online tutorials amd libraries for Arduino only. Sigh.
  • http://www.vexrobotics.com/vexiq
  • Astro-Pi (now called SenseHat) - an add-on board for the Raspberry Pi with sensors and an rgb LED grid. Use to teach kids programming with an interface to the real world. Flew on the ISS. See https://astro-pi.org/resources/
  • micro:bit - A small, cheap microprocessor board with sensors, LED's, Bluetooth that was given to UK schoolchildren to learn coding. There are a number of ways to code and interact with the device. At the minimum, Yyou can code on a smartphone and send code to the micro:bit via Bluetooth. See: http://microbit.org/

Robot Building Blocks edit

Places where TCLers may find components.

Central Processors


Motors, Actuators and other Devices


Land mobility

Water mobility

PYK 2016-05-08: Do either of these companies employ Tcl?

  • Underwater Robotics - A new underwater robotics company specialized in underwater thrusters and actuators.
  • Blue Robotics - a relatively new company which recently launched its flagship T100 and T200 underwater thruster. They also now manufacture waterproof micro-controllers and actuators.

Air mobility


  • Lego Mindstorms - Lego provides an EV3 programming software to connect and control components.
  • Vision - opencv.org is an open source computer vision library. It does not appear to have a tcl API, though.

From the history File edit

  • This comp.lang.tcl post from 1994 reads like something that could have been posted last week: Tcl software to control a robot for a robot competition.
