Autonomous/RC Human Bot

intro:18+
I am a 24 yr old student at York Technical Institute studying electrical engineering and this is my robot that I have been building for a project and wanted to share with all students, educators, and hobbyists.

This  robot can be controlled via a PC, remote control or Microcontroller.

Building a robot is all about creativity, how it is controlled, and intelligence.

This robot is built from:

• 13 Parallax and hitec servos
• home made pan and tilt head camera system
• servo erector set brackets with ball bearings
• erector set parts as body
• lynx motion tank tread kit
• wireless camera for live video streaming
• parallax ping sensors
• LED light strips for headlights (24 LEDs)
• parallax Bs2 and bs2px microcontrollers
• parallax Propeller microcontroller
• 2 parallax HB-25 motor controllers
• parallax Propeller usb servo controller
• spektrum DX5e reciever and transmitter
• 2 12 volt 6mm shaft (50:1 gear ratio) motors
• parallax LCD screen
• Misc. sensors
• different software programs such as roborealm for object tracking and more.
• Reedy LiPo 7.4V 1800mAh lithium battery pack
• Reedy LiPo 14.8V 3600mAh lithium battery pack

If you would like to build a robot similar to this but would rather make something cheap and easy all you need is what I included in my last page. I started with something much smaller and not as complex as this and in time I advanced. You can modify and change anything you want but you have to be creative and willing to learn. Enjoy!.

 

Step 1 Building the base

The base of the robot consists of 6 very strong and durable lexan panels with a tri track tank tread kit that wraps around 6 sprockets on each side. The sprockets interlace with the treads like a timing chain  locking them in so that there is no slipping. The tracks replicate the real design and work very well even with higher speeds. Here is a step by step guide on how to build the base. After you assemble the base you can organize your electronics and make a plan on what to put onto the base. You can drill holes very easy to mount any extra parts if necessary. This base is fully customizable and can handle a good amount of weight.




Step 1.
Attach four 3" aluminum bars to the inside pair of lexan panels as shown. Use 4-40 x .375" hex screws. 
Step 2.
Attach 1.5" hex standoffs to the lexan panels as shown. Use 4-40 x .375" screws.
Step 3.
Attach the motors, using four 3mm x 8mm screws. Make sure the motor shafts and the hex standoffs are on the same side of the lexan panels.
 Step 4.
Install the hubs onto the motor shafts. Align the hub to be flush with the end of the motor shaft. Tighten the set screw down firmly.
Step 5.
Install the sprockets onto the hubs. Take your time to make sure teeth on the sprockets line up! Use two 4-40 x .625" screws per side.
Step 6.
Prepare the idler sprockets. Install the two sprocket halves back-to-back on the long end of the idler hub. Take care to make the teeth on the sprockets line up! Attach them with two 3mm x 8mm screws. Make four idler sprocket assemblies.
Step 7.
Attach ball bearings to the idler sprockets, depending on which version of the idler hub you have. Install the idler sprockets into the side panel. Slide twelve nylon bushings over the nylon standoffs.
Step 8.
Install the outer lexan panels to close up the assemblies. Use twelve 4-40 x .375" screws. 
Step 9.
Wrap the 21-segment track assembly around the sprockets, push the axel in and secure with two nylon snap rivet fasteners. These parts are included with the track kit, not the chassis kit.
Step 10.
Take a small  break.
Step 11.
Attach 1.5" hex standoffs to the bottom panel as shown. Use 4-40 x .375" screws.
Step 12.
Attach the top panel . Use six 4-40 x .375" screws.
Step 15.
Attach the track assemblies to the chassis. Use eight 4-40 x .375" screws.
You can install the  base rotate using the top screws from the standoffs.
Step 17.
Push the capacitor legs through the holes in the motor terminals. Bend the capacitor legs down onto the terminals.
Step 18.
Push the motor wire connectors onto the motor terminals. Make sure to put the red wires on (+) and the yellow wires on (-).

how much did it cost?

[axeman911]

awesome!!!!!!!!!!!!!!!

[headlessknight]

he looks like johnny 5 from short circuit

[rocket_man]

Alright now i understand electronics and really want to start in robotics and build a robot like this that i can control from my pc is there anyway you could help or at least point me in the right direction thank you

[pixarstudio]

AWESOME ROBOT!!!!!!!

[drakesword]

Is the raised center point on the tracks just for aesthetics or is there an actual functional reason for it?

[IAMTHEBOT]

It's raised because thats the tri track design but with the motor at that location it provides bot with more track ground clearence, stability and torque so it doesn't get stuck as easy
